This topic describes the cookies used in connection with Video Cloud Smart Players and describes how to disable the cookies, should you wish to do so. 

Note: For information on the use of cookies in Brightcove Players, see Brightcove Player Cookies.

Video Cloud uses cookies for the following purposes:

Bandwidth detection cookie

When you use FMS streaming or progressive download to deliver videos (not Akamai HD streaming, Akamai uses its own bandwidth detection), 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.

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