VP9 is a new added codec support, not a new usage. So you can find in some SDK's codec setting API guide, VP9 codec is added as new a video codec choice. Now JS, Windows, Android SDKs can support VP9. Since now VP9 codec has no hardware acceleration, so its performance in Android mobile devices varies depending on the device capability.
I looked at the JS SDK and did not find any reference to codec setting.
What is the best way to force the web browser to use a given codec (VP8, VP9 or H.264) in your JS basic_example ?
And more generally, since CS is doing transcoding, could you describe a bit how the codec selection is working? Is there some type or capability exchange with priorities?
Thanks a lot for the help
