>WebM only recently added AV1 support to its container format

I was unable to find any evidence of this anywhere I looked. For instance this webpage: https://www.webmproject.org/docs/container/ shows only VP8 and VP9 as acceptable video codecs.

Indeed you are right, my mistake! While ffmpeg allows writing AV1 streams to WebM containers, it's not officially supported by the spec. I'd be interesting to know whether Firefox and Chrome support playback of these WebM AV1 streams though.

Any idea why they flipped the switch on that? Seems irresponsible when .mkv will do in all circumstances.
