If you're really serious about writing MP4/MOV files, I would not use
Live555 code for that (Live555 is "Source-code libraries for standards-based
RTP/RTCP/RTSP/SIP multimedia streaming"; it is not an MP4/MOV container
library).  Rather, I'd consider something like mp4v2, or ffmpeg's container
code.
