Comment (by Ferdi Scholten):
Done some more testing in 2pass transcoding:
Converting the input video to I420 (test2.y4m) rawvideo. Transcoding to
av1 with libaom to these containers:
webm -> transcodes fine
mkv -> transcodes fine
mp4 -> with every frame: ''[vost#0:0/libaom-av1 @ 0x55bf6e589540]
Overriding packet duration by frame rate, this should not happen'' Output
video is fine
Also used aomenc to transcode test2.y4m to webm with same parameters as
libaom, no problem and fast! (speed of this encode is about 150% of that
of FFmpeg).
Transcoding the original test2.mkv (h264 video) directly to av1 in these
containers:
mkv -> segfault at the end of the transcode
mp4 -> with every frame ''[vost#0:0/libaom-av1 @ 0x55bf6e589540]
Overriding packet duration by frame rate, this should not happen''
followed by segfault at the end of the transcode. Resulting file cannot be
played. [mov,mp4,m4a,3gp,3g2,mj2 @ 0x5579892b3840] moov atom not found
