 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.
