Hi guys.

I get that when viewing an AV1 file's properties in Gnome's Files - Gnome Video would not playback such a file.
I am asking here for I wonder if this is Gnome-specific issue for... other popular media players, in Fedora, play such file just fine.
Or, perhaps it's OBS issue when records into AV1 ?  I've tried both FFmpeg VAAPI and QuickSync for video encoder, which result in the same issue.

many thanks, L.
