from email (some assisted by AI):
Steps to reproduce
- Keyframe cut enabled
- Cut a video
Only happens on some files.
Expected behavior
No corruption. Used to work in v3.64 (maybe?). Output file from v3.64 with ffprobe:
ffprobe -v error -show_entries stream=codec_name,duration,nb_frames:format=duration,size -of json ".\original-00.00.00.000-00.00.30.000_old.mp4"
{
"programs": [
],
"stream_groups": [
],
"streams": [
{
"codec_name": "hevc",
"duration": "30.046683",
"nb_frames": "1801"
},
{
"codec_name": "aac",
"duration": "30.004000",
"nb_frames": "1408"
}
],
"format": {
"duration": "30.046683",
"size": "222731273"
}
}
Actual behavior
Output is corrupted / unplayable (not sure what that means exactly). Output file from 3.67.1 gives error in ffprobe:
ffprobe -v error -show_entries stream=codec_name,duration,nb_frames:format=duration,size -of json ".\original-00.00.00.000-00.00.30.000_new.mp4"
{
[extract_extradata @ 0000029729fc4280] No start code is found.
.\original-00.00.00.000-00.00.30.000_new.mp4: Invalid data found when processing input
Cutting manually with ffmpeg to cut video works:
# WORKS:
ffmpeg -i "G:\vr\tocut\original.mp4" -t 30 -c:v copy -bsf:v hevc_metadata=aud=insert -c:a copy -tag:v hvc1 -movflags +faststart -y "G:\vr\tocut\test-aud.mp4"
Without the AUD part or HEV1 it usually would not play:
# DOES NOT WORK:
ffmpeg -i "G:\tocut\original.mp4" -t 30 -c:v copy -bsf:v dump_extra=freq=keyframe -c:a copy -tag:v hvc1 -movflags +faststart -y "G:\tocut\test-dump-extra.mp4"
Suggests AUD part is needed, and suspects this problem is about in-stream AUD handling and preserving. AI also initially sugested that old Losslesscut version is looking for keyframes to match more closely but I am not so sure.
