This article describes the cookies used in connection with Brightcove's out-of-the-box Video Cloud players and describes how to disable the cookies, should you wish to do so. 

Video Cloud players use cookies for the following purposes:

Bandwidth detection cookie

When you use FMS Steaming or Progressive Download to deliver videos (not Akamai HD streaming), Video Cloud Flash players use a cookie to detect the initial bandwidth of a viewer's computer or device. This cookie helps to significantly improve initial rendition selection. If you disable this cookie, Video Cloud will still detect bandwidth by using the Brightcove Bootloader swf. Without the cookie, this must be done on each player load, consuming more bandwidth and possibly resulting in a poorer quality initial rendition.

If, in addition to disabling the bandwidth detection cookie, you add the parameter <param name="useClientSideBandwidthDetection" value="false" to the player publishing code, bandwidth detection will be disabled completely.

Characteristics of the bandwidth detection cookie

The cookie that detects bandwidth is enabled by default; to disable, or re-enable this cookie see Disabling Video Cloud Player Analytics Cookies below.

Video quality analytics cookies

Video Cloud players use cookies to collect information about the quality of Video Cloud video delivery. This information enables Brightcove support and development teams to monitor and improve the quality of service and to troubleshoot video quality issues. If you disable these video quality analytics cookies, Video Cloud will not collect these analytics on the quality of the delivery of your videos. If you are a Media Analytics customer, these cookies must be enabled or Media Analytics will not be operational.
