[Ffmpeg-devel] H264 Parsing problem

I encounter something weird during stream copy :

wget ftp://ffmpeg:ffmpeg at ftp.smartjog.net/H264_GOP_125.mp4

take that sample, ffmpeg -i H264_GOP_125.mp4 -vcodec copy test.mp4

You will see that 2 frames are broken, I compared both packet sizes in
the demuxer and in the muxer and they get corrupted, of course, 2 times.
The corruption does not happen in nal reformating.

I think something weird is happening, maybe during codec parsing ?
