What about AV1 codec support ? Encoding, decoding, no support at all ?
I have tried to load the demo file at without success : black screen, only few lines of random colours at the bottom. FourCC code for codec not shown in info dialog box. Also, I have not found an av1 codec option for encoding.
I use Avidemux 2.7.0 (not tested 2.7.1).
Thanks !



Any development on this front?
I figure it isn't yet implemented, do we know if it's being worked on?


Not that I were aware of. Not on my present todo list* either.

*) The todo list:

- evaluate options of fixing HEVC hw accel. decoding on Windows with Intel graphics;
- fix audio in fragmented mp4, currently not supported by the mp4 demuxer.

A luxury wish, probably out of reach: implementing a libvpx-based VP9 encoder.


I feel like VP9 is less of a priority than AV1 since big corps have already started pushing it as a successor to VP9... It is based on it after all.
Just need to be able to remux it in copy mode at the very least. Seems we can demux an MP4 with AV1, but can't use copy mode and remux it back into an MP4 for some reason.
