It is possible to put a vp9 video stream and a aac audio stream into a mp4 container. Firefox and Chromium play such a mp4, too.

Can you add support for this?

    P.S.

    An example mp4 file can be played at the bottom of this web page (video has annoying noise)
    Direct link to that mp4 file
    According to mediainfo the video stream has the format "VP9" and the audio stream has the format "AAC LC".

    Yeah, this shouldn't be an issue. I'm just busy with a roadtrip until after the first week September
