Changes
Context
As announced last month, VP9 is now supported and should provide the same video quality with less bandwidth / data transfer required:
https://getstream.io/blog/vp9-enhanced/
We saw lots of quality drops during NO-THING and from my initial testing, VP9 seems to help a good amount. Note that this currently only helps Chrome and Android devices — Safari and IOS still use h264 because of hardware acceleration, and Firefox has some "intermittent" issues for now when not streaming using vp8.
GetStream/stream-video-js#1434
Testing
Verified locally that viewing my stream in Firefox looks the same, and viewing in Chrome looks better overall (still drops sometimes, but it basically shifts the quality window up and prevents the stream from looking like a baked potato when I open it up.)
