You are correct. There are only two bitstream formats: the NAL unit 
stream format and the byte stream format
(ISO 14496-10 Annex B).

I apologize for confusing you by misusing the term 'MP4-compliant 
stream'. The so called 'stream'
should be more precisely called 'AVC sample structure within MP4 file 
format (ISO 14496-12)', which is
part of the AVC file format (ISO14496-15) definition. That's why ffmpeg 
does the transformation in MOV muxer.

Regards,
