I did not think that my ad-hoc hack was worthy of being proposed for
inclusion in ffmpeg. If someone here thinks otherwise, I'd be happy to
publish what I have done.

As Unix does not provide any API to split a big file or truncate it from the
beginning, I definitely need small fragments that can be moved
independently. And therefore either a new format or a new protocol so that
the video encoders and players see these fragments as a single vide.

The format of the packets in the fragments could indeed have been MPEG-PS or
MPEG-TS, and I hesitated, but in the end I decided they were too complex for
my needs, and used a custom simple header system.
