Sources Refresh
Brightcove video sources have a Time To Live (TTL) timestamp associated with it which, once expired, video playback will not be possible through that source. The bcPlayer automatically checks for sources TTL expiration in the following situations:
- When starting a video playback for the first time.
- When switching to a previous or next video in a playlist.
If a Brightcove video source is detected to be expired, it’ll be automatically refreshed by:
- Retrieving updated source URL from the Playback API.
- Reset the video
urlContentNode field. Keep in mind this step may trigger anybcPlayer.contentobserving functions.
Once the video sources are updated, bcPlayer will resume the requested action (next/previous, play the requested video, load CSAI/SSAI handlers, complete the ongoing metadata loading process) with the updated sources in place.
Voice Controls
Allows users to control the video playback through voice commands. These voice commands are captured by a supported Roku Remote Control as well as the Roku mobile app and sent to the Roku app. With the OOTB Roku UI most of these commands are handled natively. With a custom UI experience the Brightcove SDK will automatically handle the commands. Learn more.
OOTB UI/UX
- Basic Commands.
- play - Start playback if paused or stopped / resume playback if paused.
- pause - Pause playback.
- ok - Pause / resume playback.
- replay - Rewind playback 10 to 25 seconds (time depends on application's implementation).
- rewind - Rewind playback until another command is received and processed.
- forward - Fast forward playback until another command is received and processed.
- Enhanced commands.
- start over - Start playback from the beginning.
- seek - Skip playback forwards or backwards by the specified time.
- next - Play next video when having a playlist.
Brightcove Generic Stream Concurrency
The Generic Stream Concurrency allow users to limit stream concurrency using a heartbeat mechanism without the need for DRM. Generic Stream Concurrency allows you to specify the maximum number of video streams a particular user can watch simultaneously. Limiting stream concurrency will help the user to prevent their content being stolen or illegally watched through the theft or inappropriate sharing of credentials.
In order for the Generic Stream Concurrency feature to work, a JWT must be provided in the bcPlayer.credentials.auth_token property and the bcPlayer.enableGsc flag must be enabled.
Brightcove Analytics
The following events and their respective fields will be sent automatically to Brightcove by the SDK. The end user can provide the information for most of the fields in each event. Alternatively, the SDK will attempt to build it and include it in the events. Otherwise, some fields won't be sent. Learn more.

Sample App
The Roku SDK Sample App provides a set of Roku SDK application examples to help you learn about the Roku SDK components and features in a practical environment.
The README.md file provides all the details on how to set it up, configure, customize and launch
Setup
To setup Brightcove Roku SDK in a Roku channel you first need to request access to the SDK package file. Since Roku’s ComponentLibrary allows packages to be imported and loaded both locally and remotely into a Roku channel, Brightcove provides two different ways for developers to gain access to the SDK package file.
Package Sources
The Roku SDK library package sources can be obtained from https://players.brightcove.net/roku-sdk. Since Roku SDK releases use Semantic Versioning, the URL endpoint will vary depending on what release version of interest. It’s possible to obtain specific versions of the Roku SDK package like so:
https://players.brightcove.net/roku-sdk/{MAJOR-VERSION}.{MINOR-VERSION}.{BUILD-VERSION}/roku-sdk.pkg
Where MINOR-VERSION and BUILD-VERSION are optional, but MAYOR-VERSION is always required.
A full list of available Roku SDK versions is included in the changelog.
Brightcove always recommends the latest Roku SDK version, but if you have specific need of a version, you can specify version numbers in the URL.
For example, if we assume that these versions were available:
- 1.0.0
- 1.0.1
- 1.2.0
- 1.2.1
- 1.2.2
- 1.2.3
- 2.0.0
The following examples specify how the Roku SDK packages could be retrieved based on the requested version:
https://players.brightcove.net/roku-sdk/1/roku-sdk.pkg- refers to the most recent version in the v1 major release. In this example, it would refer to the v1.2.3 release.- Keep in mind that if the v1.2.4 or v1.3.0 versions were released, this endpoint would retrieve those packages instead.
https://players.brightcove.net/roku-sdk/1.0/roku-sdk.pkg- refers to the most recent version in the v1.0 minor release. In this example, it refers to the v1.0.1 release.https://players.brightcove.net/roku-sdk/1.2.3/roku-sdk.pkg- in this case, refers to the v1.2.3 release.
It’s also possible to retrieve the most recent version of the Roku SDK library package from the following endpoint:
Changelog
The changelog can be retrieved from the following endpoint. A full list of available Roku SDK versions is included.
Loading the library directly from the source
In this case the Roku SDK package URL can be set directly into the ComponentLibrary uri field. The ComponentLibrary node will handle the package file download and loading process automatically. For example, to load the latest v1 major release into a Roku channel, you can follow these steps:
In the scene XML component, create the
ComponentLibrarynode and set itsidandurifields.The
urifield contains the SDK package URL.The
idfield is used during the library components initialization.
<?xml version="1.0" encoding="utf-8" ?> <component name="MainScene" extends="Scene"> <interface> <!-- your mainscene fields here --> </interface> <script type="text/brightscript" uri="MainScene.brs"/> <children> <ComponentLibrary id="bcLib" uri="https://players.brightcove.net/roku-sdk/1/roku-sdk.pkg" /> </children> </component>- In the
init()function of the Scene's brightscript file, set up the ComponentLibrary reference and an observer for theloadStatusfield so you can detect when the SDK library is successfully downloaded and ready to be referenced.sub init() m.bcLib = m.top.findNode("bcLib") m.bcLib.observeField("loadStatus", "onLoadStatus") end sub sub onLoadStatus(ev) status = ev.getData() if status = "ready" then ' bcLib was successfully downloaded and all its components are now accessible else if status = "loading" then ' bcLib package is currently being downloaded else if status = "failed" then ' Something went wrong with the bcLib download/load process. ' Please check if the package URL was properly set. end if end sub
Loading the library locally
In this case, you should manually download the Roku SDK package file from Brightcove sources and embed it into a Roku channel. In this process the library is simply loaded from the internal channel’s file structure at runtime. This is the recommended approach as it’s much faster and efficient than letting ComponentLibrary download and load the SDK package. For this approach, the following steps can be taken:
- Download the SDK package manually.
- Place the SDK package in the Roku channel file structure (feel free to rename the file, in this case we named it bcLib.pkg). The exact location doesn't matter. In the following example, it was placed in the lib directory.
- In the scene XML component, create the
ComponentLibrarynode and set theidandurifields.- The
urifield contains the bcLib.pkg file local path. - The
idfield is used during the library components initialization.
<?xml version="1.0" encoding="utf-8" ?> <component name="MainScene" extends="Scene"> <interface> <!-- your mainscene fields here --> </interface> <script type="text/brightscript" uri="MainScene.brs"/> <children> <ComponentLibrary id="bcLib" uri="pkg:/lib/bcLib.pkg" /> </children> </component> - The
- In the scene's
init()function of the Scene's brightscript file, set up the ComponentLibrary reference and an observer for theloadStatusfield so you can detect when the SDK library is successfully loaded.sub init() m.bcLib = m.top.findNode("bcLib") m.bcLib.observeField("loadStatus", "onLoadStatus") end sub sub onLoadStatus(ev) status = ev.getData() if status = "ready" then ' bcLib was successfully downloaded and all its components are now accessible else if status = "loading" then ' bcLib package is currently being downloaded else if status = "failed" then ' Something went wrong with the bcLib download/load process. ' Please check if the package URL was properly set. end if end sub
Loading the library dynamically
It’s recommended to set the ComponentLibrary in the scene’s children section with the proper package URL so that the library loading process starts immediately during the Scene initialization, but depending on the use case, it could also be useful to be able to dynamically load the library anywhere in the channel. This can be done by initializing the ComponentLibrary node in the brightscript code as such:
sub init()
' this can be placed anywhere in the Scene node code,
' although usually we want it to load as soon as possible so we can immediately access its components
m.bcLib = createObject("roSGNode", "ComponentLibrary")
m.bcLib.observeField("loadStatus", "onLoadStatus")
m.bcLib.id = "bcLib"
m.bcLib.uri = "<path_or_url_to_the_pkg_file>"
end sub
This allows you to control where and when exactly they want to load the Roku SDK library package into their Roku channel.
Accessing Roku SDK components
Once the SDK library is successfully loaded (ie, the ComponentLibrary loadStatus field is ready), an instance of any of its components can be created like so:
' creating an instance of the bcPlayer component from the bcLib library
' 1 - create an instance of the bcPlayer node
' This won't make the bcPlayer node visible in the app, it still needs to be added to the node tree list after this step
m.bcPlayer = createObject("roSGNode", "bcLib:bcPlayer")
' 2 - create an instance of the bcPlayer node and append it to the parentNode node.
' If parentNode is already in the node tree list and is visible, this will also make the bcPlayer node visible in the app
m.bcPlayer = parentNode.createChild("bcLib:bcPlayer")
In place of the usual SGNode component name (in the createObject and createChild functions), an external library component must be referred as: “
<ComponentLibrary-id>
:
<component-name>
".
bcPlayer component
The bcPlayer component is the main SDK node as it enables both Brightcove sources and external sources video playback in Roku channels. This node essentially extends Roku’s native Video node, allowing all its fields to be easily accessed for further customization options. It is possible to configure the appearance of some elements in the node as well as some behaviors and flows by customizing the node fields values.
An instance of this node can be created like so:
m.bcPlayer = createObject("roSGNode", "bcLib:bcPlayer")
Once an instance of the node is available, it’s possible to customize it by setting up its fields. All the fields default values are listed below.
m.bcPlayer = createObject("roSGNode", "bcLib:bcPlayer")
m.bcPlayer.observeField("on", "onEvent") ' read-only field
m.bcPlayer.observeField("adPlaying", "onAdPlaying") ' read-only field

Fields
The bcPlayer node is configured through a set of fields. Since it extends the native Video node, all native fields are also accessible; these can be checked out in Roku documentation.
The following tags are used in this section to make the identification of the different types of fields easier.
<VALUE_TYPE>Specifies the expected type of a field value or ASSOCIATIVE ARRAY key value (e.g., string, float, integer…).OPTIONALSpecifies an optional field or ASSOCIATIVE ARRAY key. If an optional field isn’t specifically set, theDEFAULTvalue is be used.REQUIREDSpecifies that a field or ASSOCIATIVE ARRAY key is required (write-only properties) or is always present (read-only properties). If a required field is not set, an error message will be presented in the built-in logger.DEFAULTSpecifies the default value of a field or ASSOCIATIVE ARRAY key.NATIVEIdentifies a native field. These fields are aliases or references of a native Roku node fields. Roku documentation should be consulted for a more detailed description of these fields.CONTROLIdentifies fields that can control the video playback in any way.
Credentials
ASSOCIATIVE ARRAY OPTIONAL
Configures Brightcove API credentials. It should contain the account ID as well as the policy key. These are used to retrieve video metadata from the Brightcove Playback or EPA API.
If the credentials aren’t provided, the bcPlayer node will only be able to playback videos from external sources through the bcPlayer.loadCustom function.
Possible Values:
An ASSOCIATIVE ARRAY containing the following keys:
account_idSTRINGREQUIREDSpecifies Brightcove API user account ID.
-
policy_keySTRINGOPTIONALSpecifies the user policy key required to access the Playback API.

auth_token: "<brightcove_user_auth_token>"
}
})
watermarkToken
STRING OPTIONAL
Configures the Forensic Watermarking token, which is required when playing watermarked encoded Brightcove sources.
Playing a watermarked video without the watermarkToken field properly set will result in a playback error.
Please check Videocloud documentation for more information on Forensic Watermark.
Possible Values:
A string containing the Forensic Watermarking token.
""DEFAULT
Code Snippet
m.bcPlayer = createObject("roSGNode", "bcLib:bcPlayer")

' ...other fields here...
watermarkToken: "<forensic_watermarking_token>"
})
streamPreference
ARRAY OPTIONAL
Configures sources types/containers preferences ordered by the priority each type/container will have when filtering the available video sources.
This allows you to setup the bcPlayer so that only certain stream types/containers are used or ignored, and the order in those sources will be filtered.
Playing a video in which no sources are listed in the streamPreference field will result in an error.
Find more information on how the sources are parsed and filtered in the Sources Selection section.
Possible Values:
An array containing any combination of the following values:
hlsdashmp4DEFAULT["hls", "dash", "mp4"]
Code Snippet
m.bcPlayer = createObject("roSGNode", "bcLib:bcPlayer")
m.bcPlayer.streamPreference = ["dash"] ' will only playback DASH sources
' or
m.bcPlayer.setFields({
' ...other fields here...
streamPreference: ["dash", "mp4"] ' will play DASH sources. If no DASH source is availble, will play MP4 sources
})
drmPreference
ARRAY OPTIONAL
Configures DRM encryption systems preferences ordered by the priority each DRM system will have when filtering the available video sources.
This allows developers to setup the bcPlayer so that only certain DRM encrypted sources are used or ignored and the order in which the sources will be filtered through.
Playing a video in which no DRM encrypted sources are listed in the drmPreference field will result in an error. The none value forces the selection of sources with no DRM encryption.
Find more information on how the sources are parsed and filtered in the Sources Selection section.
Possible Values:
An array containing any combination of the following values:
widevineSupported on HLS and DASH sources only.playreadySupported on DASH sources only, ignored on HLS sources.noneDEFAULT["widevine", "playready", "none"]

})
logLevel
INTEGER OPTIONAL
Configures the logging level on the bcPlayer node. Only the specified messages will be triggered.
If set to -1 no logging messages will be triggered. In a production environment it's recommended to set it to -1 to avoid the execution of the logging internal functions.
Possible Values:

spinnerConfig
ASSOCIATIVE ARRAY OPTIONAL
Configures the custom loading spinner appearance.
When using Roku’s native Video node UI/UX, this spinner is only visible during the execution of API requests, as the native Video node contains its non-customizable loading spinner, which is visible during buffering operations.
Possible Values:
An Asociantive Array with the following optional keys:
URLSTRINGOPTIONALSpecifies the spinner image path
DEFAULTInternal PNG image path which looks like so:
sizeINTEGER/FLOATOPTIONALSpecifies the size (width and height values) of the spinner image.

opacity: 0.8 ' sets an opacity of 80%
}
})
loading
BOOLEAN OPTIONAL
Controls the custom loading spinner visibility. This field is used by internal functions but it also allows the custom spinner to be controller externally if needed.
Keep in mind that
- The OOTB UI has its own loading spinner. This field is independent from the OOTB UI built in loading spinner.
- Internal bcPlayer functions will automatically toggle the loading field value depending on what operations are being executed.
The appearance of the loading spinner can be customized through the spinnerConfig field.
Possible Values:
falseDEFAULTHide the custom loading spinner.trueShow the custom loading spinner.
Code Snippet
m.bcPlayer = createObject("roSGNode", "bcLib:bcPlayer")
m.bcPlayer.loading = true
' or
m.bcPlayer.setFields({
' ...other fields here...
loading: true
})
retryOnError
BOOLEAN OPTIONAL
Toggles the retry on error feature which, when enabled, allows bcPlayer to automatically retry video playback with a different video source if a playback error is triggered during the initial video buffering process.
If all the available video sources fail to play an error will be triggered.
The retry on error flow follows the sources type and DRM encryption preferences/priorities set in the bcPlayer.streamPreference and bcPlayer.drmPreference fields.
This flow is only relevant at the initial source loading, ie, a playback error triggered mid-playback will not trigger the retry on error flow.
This feature is not applicable to CSAI videos.
Possible Values:
falseDisables the retry on error flow.trueDEFAULTEnables the retry on error flow.

retryOnBufferTimeout
BOOLEAN OPTIONAL
Configures the retry on buffer timeout feature which, when enabled, allows bcPlayer to automatically retry video playback with a different video source when a buffering timeout error occurs.
If the bcPlayer.bufferTimeout configuration is disabled (ie, is set to 0), this feature is ignored.
The bcPlayer.on.timeout event data contains a retry flag which indicates if bcPlayer is going to retry the playback with a different source.
Possible Values:
falseDEFAULTDisables the retry on buffer timeout feature.trueEnables the retry on buffer timeout feature, ifbcPlayer.bufferTimeoutis enabled.

retryOnBufferTimeout: true
})
...
sub onTimeout(ev)
' ev.getData() -> {contentIndex: Integer, bufferingStatus: AssociativeArray, retry: Boolean}
end sub
closeOnBack
STRING OPTIONAL
Configures the back key press action.
It’s set to hard by default, which means that when the user presses the back key, it’ll completely terminate/kill the bcPlayer instance.
Setting it to soft causes the bcPlayer to do a soft close, which means that the current playback session is stopped and terminated but the bcPlayer node instance is kept alive and ready to receive other commands.
This behavior can be disabled (by setting this field to off), in which case developers could capture the back key press through the bcPlayer.on.keyEvent event listener and handle it manually. This also means that the bcPlayer node will let the back key event bubble up, so the app should be prepared to capture and handle it in a onKeyEvent function.
If an invalid value is set, it’ll automatically be reset back to hard.
Possible Values:
offDisables the close on back action.softSoft closes the bcPlayer when the user presses the back key.hardDEFAULTHard closes the bcPlayer when the user presses the back key.
Code Snippet
m.bcPlayer = createObject("roSGNode", "bcLib:bcPlayer")
m.bcPlayer.closeOnBack = "off" ' disable the close on back action

' somewhere in a bcPlayer parent node...
function onKeyEvent(key as string, press as boolean) as boolean
handled = false
if key = "back" then
closePlayer() ' developers should handle the back key press here since the closeOnBack action was disabled
handled = true
end if
return handled
end function
closeOnFinished
BOOLEAN OPTIONAL
Configures the bcPlayer behavior at the end of video playback.
When enabled (i.e., set to soft or hard), the bcPlayer will automatically close once the video playback reaches the end. In a playlist, this behavior depends on the following playback configurations:
bcPlayer.playback.autoPlayNext- if theautoPlayNextflag is enabled, once a video reaches the end, it'll play the next video in the playlist, if available.bcPlayer.playback.loop- if theloopflag is enabled, once the last video in the playlist finishes, it'll loop the playlist and play the first video.
When disabled (i.e., set to off), developers should handle the finished event manually through the bcPlayer.on.finished or the bcPlayer.csai close event.
If an invalid value is set, it'll automatically be reset back to hard.
Keep in mind that the close action will trigger a bcPlayer.on.close event, where the close type (soft or hard) can be checked.
Possible Values:
off: Disables the close on finish action.soft: Soft closes the bcPlayer when video playback finishes (depending on whether it’s playing a playlist or not and on the autoPlayNext and loop configuration values).hardDEFAULT: Hard closes the bcPlayer when video playback finishes (depending on whether it’s playing a playlist or not and on theautoPlayNextandloopconfiguration values).

enableDialogs
BOOLEAN OPTIONAL
Configures bcPlayer to show error dialogs when an error occurs.
It’s enabled by default; you can disable it and capture the errors through the bcPlayer.on.error event.
These dialogs appearance can be customized through the dialogTheme field.
Possible Values:
falseDisables error dialogs.trueDEFAULTEnables error dialogs.

enableGSC
BOOLEAN OPTIONAL
Toggles Brightcove Generic Stream Concurrency (GSC) feature on and off in bcPlayer.
Generic Stream Concurrency allows developers to define the number of video streams that a specific user can watch concurrently. Limiting stream concurrency helps preventing content being stolen or illegally watched through the theft or inappropriate sharing of credentials. Learn more.
Possible Values:

bufferTimeout
INTEGER OPTIONAL
Configures the buffering timeout period, in seconds. This configuration allows developers to setup a timer which is initiated once the initial video buffering begins and at the end of which a timeout error will be triggered if the video playback hasn’t yet initiated.
Setting it to 0 disables the buffering timeout timer.
When the video buffering times out, a bcPlayer.on.timeout event is triggered. Additionally, if the bcPlayer.retryOnBufferTimeout configuration flag is enabled, the bcPlayer will retry the playback with a different source, if available. Otherwise, a dialog window is shown (if bcPlayer.enableDialogs is enabled).
Possible Values:
- A positive integer value (seconds).
DEFAULT0buffering timeout disabled.

A native message triggered by RokuOS is presented to the app user informing that the network connection was lost. An error is eventually triggered but it’s not immediate as the player waits for the conditions to resume video playback. We provide this event in case developers need to implement custom behaviors/workflows to handle this situation. |

ssai
NODE
Allows to configure SSAI support in the bcPlayer.
Live video streams only support SSAI service provided by Brightcove.
When setting up SSAI in a Brightcove video, the bcPlayer will automatically set the adsData field in the video ContentNode node. This field stores all the SSAI details, including the parsed VAST/VMAP data and it’s required to initialize RAF. Currently Brightcove SSAI sources will automatically create the adsData field, but it should also be possible to adapt it to work with custom metadata and other SSAI providers (VOD sources only), like so:
m.bcPlayer = createObject("roSGNode", "bcLib:bcPlayer")
' enable SSAI handling
m.bcPlayer.ssai.enabled = true
' setup the custom metadata you wish to load through the loadCustom function and add the adsData property
' this function should start video playback automatically
m.bcPlayer.callFunc("loadCustom", {
... ' add the custom metadata properties
Url: "https://my.ssai.video.url" ' make sure to set the video URL. This should be a stitched video, containing both the ads and the content
StreamFormat: "hls/dash" ' set the stream format
adsData: { ' adsData should be an AssociativeArray object
type: "ssai", ' specifies that this is a SSAI enabled video
adBreaks: < adBreaks-ad-structure> ' provide the Ad Structure array as requested by Roku. This information is usually parsed from a VAST/VMAP document
}
})
Through the bcPlayer.ssai.macros field it’s possible to specify a set of macros that will get replaced in the ad tag (please check the bcPlayer.ssai.macros field description in the table below for more details), but it’s also possible to add custom macros into the ad tag as well, by setting up the vmapMacros field in the video ContentNode node. vmapMacros should be an Associative Array object and all the key-value pairs provided will be added into the ad tag (please be aware that it doesn’t check if the macro is already present in the ad tag, if it is, it’ll add it anyway).
sub init()
m.bcPlayer = createObject("roSGNode", "bcLib:bcPlayer")
' enable SSAI handling
m.bcPlayer.ssai.enabled = true
' request the SSAI ready video metadata through PAPI and disable the autoload flag so that the metadata can be adjusted before loading it into bcPlayer
' if you already have the metadata, you can skip this step and move on to the onVideoResponse() logic where the vmapMacros property is added.
rNode = m.bcPlayer.callFunc("getVideo", SSAIVideoID, { autoload: false })
if rNode <> invalid then rNode.observeField("response", "onVideoResponse")
end sub
sub onVideoResponse(ev)
data = ev.getData()
if data.code <> 200 then
' handle the error
return
end if
metadata = data.body

|
| adMeasurements |
Allows to specify custom ad measurement properties. These properties are usually retrieved for the video ContentNode, but their values can be overridden through this setting. Be aware that these properties have to be set and/or reset for each video individually.
|
| bcovToken |

csai
Allows to configure CSAI support in the bcPlayer.
bcPlayer employs Roku's Client-Side Ad Stitching (CSAS) solution for CSAI handling.
When playing videos with CSAS, RAF creates its own internal Video nodes to seamlessly stitch video content and ad content together. This means that the bcPlayer native Video fields won't be able to control video playback or get the usual playback events. Alternatively, while playing CSAS videos, the following options are available:
RAFContentRendererThis node is created and handled by RAF and replaces
bcPlayeras the playback controller. It contains most of the Video node fields so they can be observed and updated as required (such as the Videocontrol,stateandpositionfields). This node is added as a child of bcPlayer and its reference can be obtained through thestartCSAI event (available inbcPlayer.csai.event).bcPlayer.playbackThe
playbackfunction should automatically detect CSAS video playback and is able to control the video playback (if RAF allows it).bcPlayer.csai.eventThe
playbackTheeventproperty is specially important for CSAS video playback because this is where all the video content and ads playback events can be accessed. Check the table below for this list of all the supported events.
To setup CSAS in a video, the adsData property should be manually added into the metadata before loading it into the bcPlayer, like so:

Functions
The bcPlayer node also provides some functions to interact with the Video content and playback.
Load
Loads Brightcove Playback API video or playlist metadata into the bcPlayer asynchronously. Usually the data entered in the load function comes from the bcAPI component available in the Brightcove SDK which retrieves videos data from the Playback API, but it’s also used internally by the getVideo, getVideos, getPlaylist and getRelated functions.
The load function triggers a bcPlayer.on.load event reporting on the success or failure of the load process.
Parameters:
dataDYNAMICREQUIREDBrightcove videos data to load into the bcPlayer for playback. This data can represent a single video or multiple videos. The possible values are:A single video object
ASSOCIATIVE ARRAYVideo by ID/ReferenceExpected metadata object structure:
{ account_id: "<papi-video-account_id>" sources: [<papi-video-sources>], <...> },Any other properties in this object (besides
account_idandsources) are automatically set as fields of thebcPlayer.contentContentNode, taking into account the following custom specifications:If the
titleproperty isn't provided and anameproperty is,titleis set toname.titleis a native field of a ContentNode and it defines the title text shown in the top left corner of the player when using Roku's OOTB UI/UX.If the
lengthproperty isn’t provided and adurationproperty is,lengthis set toduration / 1000.lengthis a native field of a ContentNode and it specifies the length of a video in seconds. Thedurationproperty should contain the length of the video in milliseconds, if provided.If the
SDPosterUrl,HDPosterUrlandFHDPosterUrlproperties aren’t provided and a poster property is, these three properties are set to theposterproperty value.postershould provide the video poster image URL.SDPosterUrl,HDPosterUrlandFHDPosterUrlare native fields of a ContentNode and, although not required in the bcPlayer node, they might be useful in a MarkupGrid, RowList or similar Roku components.If the
liveproperty isn't provided,liveis set based on the value of thedurationproperty.liveis a native field of a ContentNode and it identifies a live video, which may impact the behavior of Roku’s OOTB UI/UX.If
durationis not provided or its value is0or below:liveis set totrue.If
durationvalue is above0:liveis set tofalse.
If the video is considered a live stream (
live=true) and the playstart property isn't provided, playstart is set to2147483647. This forces the player to start playback from the live stream position.
A playlist object
ASSOCIATIVE ARRAYPlaylist by ID/ReferenceExpected metadata object structure:
{ videos: [ { account_id: "<papi-video-account_id>" sources: [<papi-video-sources>], <...< }, <...< ], <...< }This metadata is loaded into a Video playlist ContentNode structure.

close
Initiates the close action, which depending on the parameter provided, terminates/kills bcPlayer completely (hard close) or just stops and clears the current playback session (soft close). By default, if no parameter is provided, it executes a hard close.
The hard close is an asynchronous process, at the end of which it triggers a bcPlayer.on.closed event to confirm that the close process is complete.
Once the close action is called, the bcPlayer.on.close event is also triggered specifying the type of close action that was called (soft or hard).
The close process can also be triggered internally by the closeOnBack and closeOnFinished configurations, if configured to do so.
Be aware that a hard close completely kills the bcPlayer node instance and it’s not possible to access/use its functions afterwards.
Parameters
-
killBOOLEANOPTIONAL-
trueDEFAULTTriggers a hard close action, which terminates/kills the bcPlayer instance completely.
-
falseTriggers a soft close action, which stops the current playback session and clears the content. The bcPlayer node remains on standby waiting for other commands.

Video Sources Selection
When playing a Videocloud video or playlist in the bcPlayer node through the load, playVideo, playVideos, playPlaylist and playRelated functions, the video/videos metadata is parsed and the video sources are filtered through the following stages:
| Step | Description |
|---|---|
| 1 | Sources go through an initial filtering process where one source is selected per stream type (HLS and DASH), DRM system (Widevine, Playready and no DRM) and protocol (HTTP/HTTPS). Sources are added to the mapping object according to the following prioritization rules:
Sources mapping object
|
| 2 | Once the sources mapping object is set, a single source is selected based on the values of the streamPreference and drmPreference bcPlayer config fields. This process iterates through the streamPreference array and for each stream type/container the following steps are executed until one source is selected:
|
| 3 | Once a Videocloud video source has been selected, it’s then converted into the required Video ContentNode fields. At this stage the selected source URL is also verified for any supported query parameters we might need to set, such as the Forensic Watermarking token or JWT. |
bcAPI component
This component allows for independent access to Brightcove’s Playback API without having to initialize a bcPlayer component. bcAPI extends a Task node, and as such, is controlled through the controlcontrol field.
bcAPI is able to handle multiple requests at the same time (configurable through the maxRequests field) and it also provides an interface that enables any HTTP request to be triggered.
It’s up to developers to choose the best workflow for this node, but we recommend one instance to be created somewhere during the app launch process and then referenced throughout the app.
An instance of this node can be created like so:
m.bcAPI = createObject("roSGNode", "bcLib:bcAPI")
Once an instance of the node is available, it’s possible to customize it by setting up its fields. All the fields default values are listed below.
sub init()
' create a bcAPI node reference
m.bcAPI = createObject("roSGNode", "bcLib:bcAPI")
' observe the response field to access the API responses
m.bcAPI.observeField("ready", "onAPIready")
' configure bcAPI node fields
m.bcAPI.setFields({
credentials: invalid,
logger: invalid, ' optional: provide a bcLib:Logger node instance
maxRequests: 5,
control: "run" ' initialize bcAPI task imediately
})
m.bcAPI.getVideo = {id: "<my-video-id>"}
end sub
sub onAPIResponse(ev)
response = ev.getData()
end sub
Config Fields
Credentials
ASSOCIATIVE ARRAY OPTIONAL
Configures Brightcove API credentials. It should contain the Account ID as well as the Policy Key or Authentication token. These are used to retrieve videos metadata from Brightcove’s Playback API.
If valid Brightcove credentials aren’t provided in this field, the bcAPI node will only be able to trigger HTTP requests through the request function.
Possible Values:
An ASSOCIATIVE ARRAY containing the following keys:
account_idSTRINGREQUIREDSpecifies Brightcove user account ID.
-
policy_keySTRINGOPTIONALSpecifies the user policy key required to access the Playback API.
-
auth_tokenSTRINGOPTIONALSpecifies the JSON Web Token required to:
- Provide Playback Restriction rules (Playback Rights) through Edge Playback Authorization (EPA).
- To specify License Keys Protection for HLSe content playback.
Code Snippet
m.bcAPI.credentials = {account_id: "my-account-id", policy_key: "my-policy-key"}
' OR
m.bcAPI.setFields({
' ...
credentials: {account_id: "my-account-id", policy_key: "my-policy-key"},
' ...
})
maxRequests
INTEGER OPTIONAL
Specifies the number of simultaneous requests that can be executed at the same time. If the number of requests surpass the value defined in maxRequests, these requests are put on hold until the ongoing requests are completed. It follows a FIFO approach.
Possible Values:
5DEFAULTA positive integer value.
Code Sinippet
m.bcAPI.maxRequests = 3
' OR
m.bcAPI.setFields({
' ...
maxRequests: 3,
' ...
})
logger
Specifies the Logger node reference to be used for logging purposes.
Possible Values:
bcLib:Loggerreference.
Code Snippet
logger = createObject("roSGNode", "bcLib:Logger")
m.bcAPI.logger = logger
' OR
m.bcAPI.setFields({
' ...
logger: logger,
' ...
})
Action Fields
Since bcAPI is a Task node, it's not feasible to interact with it through Functions so all the actions requested to this node are initiated through its fields. Check below the list of all possible actions this node provides.
request
Allows for the execution of any HTTP request. Brightcove credentials are not required.
Request responses can be obtained through one of two ways:
- By providing a response Node with a
responseAssociativeArray field, bcAPI will set the request response data into that field, which will then be available on any observing function. - By observing the response bcAPI output field if no response Node is provided.
This structure is exactly the same whether it’s set through the response Node or the bcAPI response field.
Possible Values:
An AssociativeArray object containing the following properties:
dataASSOCIATIVE ARRAYREQUIREDContains the request data. The following properties are possible:
idSTRINGOPTIONALA custom request ID so it can then be identified when processing the response data. Specially useful when parsing responses from the response field instead of a response Node. If not provided, defaults to “request“.
requestDEFAULT
urlSTRINGREQUIREDThe request URL.
headersASSOCIATIVE ARRAYOPTIONALRequest headers in a key-value Associative Array object. Roku’s
x-roku-reserved-dev-idheader is automatically set.methodSTRINGOPTIONALRequest method. The possible values are:
getDEFAULTpostdeleteputpatch
bodySTRING / ASSOCIATIVE ARRAYOPTIONALRequest body. If an Associative Array object is provided, it’s automatically parsed into a string before sending the request.
gzipBOOLEANOPTIONALEnables the GZIP encoding through EnableEncodings. Disabled by default.
cookiesBOOLEANOPTIONALEnables cookies through EnableCookies. Disabled by default.
http2BOOLEANOPTIONALEnables HTTP/2 support through SetHttpVersion. Disabled by default.
forceFormatSTRINGOPTIONALSpecifies how the response body should be formatted. The possible values are:
autoDEFAULTChecks for the
content-typeresponse header and if it’s set toapplication/jsonthe response body is parsed into an Associative Array object. If not, the response body is set as a string.jsonForces the parsing of the response body into an Associative Array object. This may result in unwanted results if the response content is not a valid JSON string.
stringThe request response body is set as a string.
optionsAssociative ArrayOPTIONALCustom parameters that will be passed along to the response object as is.
nodeNODEOPTIONALResponse Node with a
responsefield where the request response will be set into. If not provided (default), the response data can be accessed through bcAPI response output field.

abort
BOOLEAN
Aborts currently ongoing requests.
If a response Node was provided in the request configuration, its response field is set to the following value: {aborted: true}. This allows the response handler to be notified that the request was aborted.
Possible Values:
falseno action.trueaborts currently ongoing requests.
Code Snippet

kill
BOOLEAN
Aborts all ongoing requests and completely terminates the bcAPI Task. Once kill is requested there is no way to bring bcAPI functionality back on, so a new bcAPI node instance would need to be created.
Since this process is asynchronous, once the bcAPI is completely terminated the ready field is set back to false to notify eventual observing functions about the Task termination.
Possible Values:
falseno action.trueaborts ongoing requests and terminates the bcAPI Task.

match
Search for matching substrings in a String through a regex pattern. If the matching pattern contains N parenthetical substrings, the relevant substrings are returned as an array of length N+1, where array[0] is again the entire match and each additional entry in the array is the match for the corresponding parenthetical expression.
Uses Roku’s roRegex component internally.
Parameters:
stringSTRINGREQUIREDThe string to be searched for matching substrings.
patternSTRINGREQUIREDThe regex pattern.
flagSTRINGOPTIONALSpecifies the behavior flags. Empty string if not provided. Any combination of the following flags is supported:
iCase insensitive match.mMultiline mode. The start of line^and end of line$constructs match immediately following or before any newline in the subject string as well as the very start and end of the string. Normally, just the start and end of the string would match.sSets dot-all mode that includes newline in the.*regular expression. This modifier is equivalent to Perl's/smodifier.xSets extended mode that ignores whitespace characters except when escaped or inside a character class. Characters between an unescaped#outside a character a character class and the next newline character, inclusive, are also ignored. This modifier is equivalent to Perl's/xmodifier.
