Enable WebRTC with VP9 Codec

jesper_lai · October 20, 2020, 1:46pm

i’m using https://www.wowza.com/developer/webrtc/dev-view-publish to POC webRTC on wowza
there’s some options under VIdeo codes that I can choose, including H264, VP8, VP9

for H264 & VP8 codec, can successfully publish and play
but while choosing VP9, an error msg pop-up

Failed to set remote answer sdp: Failed to set remote video description send parameters for m-section with mid=‘1’

May I know how to correctly enable VP9 on webRTC?

Would you please share with us what you are using?

VP9 works across a lot of platforms, but not all work so well Do you have Opus as the audio codec with the vp9?

encoder
= the website provided by Wowza itself (https://www.wowza.com/developer/webrtc/dev-view-publish), I just allow webpage to use the webcam

codec
= VP9, there’s no issues on using VP8 and H.264, while choosing VP9, pop-up Failed to set remote answer sdp

audio codex = Opus as well, i always choose Opus as audio codec no matter what video codes I am using

brower
= Chrome (version 86.0.4240.111)

Yes, always use Opus as audio codec no matter what video codec I was using, never change to another audio codec
