I am using default media receiver on Chromecast and am am adding the Google Cast sender app support to chrome/web videoplayer. I need to know which bitrate stream Chromecast is rendering at a given moment for instrumentation purposes. Is there any listener that I could attach to listen for bitrate change events? Or can I poll current selected bitrate?
You cannot do that in the default/styled receiver; you need to have your own custom receiver and if you do that and use MPL (MediaPlayerLibrary), you can get that information through getQualityLevel() method. Note that you can grab the Cast-Player-Sample which is the reference receiver and update that based on your needs; that is the best starting point for a comprehensive UX-compliant custom receiver.
