Sorry to resurrect this old thread, but I have started getting videos using AV1 from one of my correspondents and find Videoredo still can't read them. I note that there is now at least some support for AV1 in FFMPEG. Any later news on plans to incorporate support in VideoRedo?
(If I have missed another thread on this my apologies, but I find VideoRedo won't let me use "AV1" as a search term, I get told it is "too short").
