Comment:
1. The very first byte_stream_nal_unit (verbiage from annex b of the H.264
standard) can contain an arbitrary amount of leading_zero_8bits, so the
position is actually correct.
2. Your ticket is missing the necessary information described
[https://www.ffmpeg.org/bugreports.html here].
3. I cannot reproduce your findings: The leading zero bytes are stripped
when muxing into mp4 and the resulting file plays fine in VLC.
So I'm closing this as invalid.
