Webrtc vp8 codec iphone Now I am starting with VP8 codec. I can see that from DefaultVideoEncoderFactory supportedCodecs includes VP8, VP9, and H264 but I don't see how to set a preferred codec (as can be done in iOS WebRTC)? In particular I would like to be able to set VP9 as the preferred codec. I’m not having any luck getting the VP8 codec to work with WebRTC, I can replicate the problem with the Wowza WebRTC test client by simply selecting VP8 as the codec. Regarding different kinds of codecs, the hardware encoder uses H. Codecs supported: AV1, VP8, VP9, H264, H265. However, when my app responds with the 200 OK SDP, H264 is not included, and VP8/VP9 are negotiated instead.
