When attempting to decode VP9 SVC frames from an IVF or WebM file there is a difference when using the default “Google VP9” video codec as opposed to the “Libvpx VP9” codec. The former renders with the lowest spatial quality while the latter renders the highest. The “Libvpx” decoder detects the dimension change while “Google” does not. Is this a bug? I am able to force ffplay to render properly by specifying ‘-vcodec libvpx_vp9’. However, VLC and Chrome (WebM) appear to use the default codec and render the lowest spatial quality. _______________________________________________ Libav-user mailing list Libav-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/libav-user
