H.264 / AVC video tracks are written to H.264 elementary streams which
can be processed further with e.g. MP4Box from the GPAC package.

So I expect it writes it out with NAL start codes, check the result
for 0x000001 markers to confirm.

The H264 elementary stream format is available from ISO at www.iso.org
