Subject: [FFmpeg-devel] [PATCH] mov: fix bit_rate calculation for fragmented MP4

Hello FFmpeg developers,
This patch fixes the calculation of bit_rate for fragmented MP4 files,
ensuring
that the reported bit_rate covers the entire fragmented file instead of only
the first fragment.
This addresses GitHub issue: https://github.com/FFmpeg/FFmpeg/issues/20450
Changes include modifications in:
- libavformat/mov.c
- libavformat/isom.h
Tested using ffprobe on sample fragmented MP4 files (12.mp4 and 21.mp4), and
the bit_rate is now calculated correctly over the whole file.
Patch attached.
Best regards,
Nariman Sayed
