BTW, the IVF file plays OK in MPC-HC albeit not seekable. Second, rav1e encoding succeeded but converting the resulting IVF file to the webm format via FFmpeg fails. (My FFmpeg build is the most recent one.) I faithfully followed the AV1 encoding guide on the FFmpeg site but it doesn't help. I didn't know why but I found out from your post that mkvmerge doesn't support muxing an AV1 IVF file as of yet. I'm a happy user of FFmpeg (CLI) on Windows 10 built by the media autobuild suite and recently I decided to try encoding an AV1 video in FFmpeg via libaom-av1 and in rav1e (since FFmpeg does not wrap rav1e yet) respectively.įirst off, FFmpeg encoding via libaom-av1 to an mkv file fails for no reason ― it simply stops encoding. + I'll ask Mosu whether the av1 inside webm specificaiton is finished.
