Build report:

Getting error "av.codec.codec.UnknownCodecError: libvpx" in below line of code:

self.container = av.open("test.webm", mode="w") self.stream = self.container.add_stream("libvpx", rate=round(frame_rate))

I tried with "vp8"/"vp9" as well but it still showing same error.

When i change the codec to "h264" =>

self.stream = self.container.add_stream("h264", rate=round(frame_rate)),

it's start working, But i need to write webm file.

I also checked av.codecs_available and its shows "vp8" and "vp9" in the available codecs list
