As far as I know, WebM only recently added AV1 support to its container format. Before that, it was already supported in MP4 and Matroska.

- lukevp 6y agoThanks, I removed the reference to WEBM in that case. MP4 and MKV are very common container formats, so being supported in WEBM, MP4, MKV doesn't seem like a differentiator.
- m-p-3 6y agoWith how versatile the MKV container is, it seems odd that it isn't the de facto container out there.
- fireattack 6y agoNot to mention WebM is (was?) literally a subset of Matroska.
- namibj 6y agoAfaik WebM is just a royalty-free subset of MKV, maybe with some exotic features omitted.
- prvc 6y ago>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/ https://www.webmproject.org/docs/container/ shows only VP8 and VP9 as acceptable video codecs.
- dindresto 6y agoIndeed 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.
- prvc 6y ago>ffmpeg allows writing AV1 streams to WebM containers Any idea why they flipped the switch on that? Seems irresponsible when .mkv will do in all circumstances.
