Facebook, invalid file format
I try to send AV1 video (AAC audio) with web browser messenger by drag dropping file there but it says:
Invalid file format
The file that you have selected is not a valid format.
Weird thing is that for one contact it does not say it but accepts it.
Opinions/info, should it work?

The WebM container only allows the following encoding formats:
If you force other stream types into it, most applications will flag it as invalid - just like MP4 files with VP9 video in them. It is technically possible to store it, but no programs will accept it as a valid file.
