Problem in using mpegtsmux

[Peter Maersk-Moller]

Hi Sina.

MPEG TS can not handle MJPEG/JPEG. No standards for that I'm afraid. Also
no standard for PSI
<http://en.wikipedia.org/wiki/Program-specific_information> description for
such a stream exist. You'll need something like MPEG-4 part 2 (XviD),
MPEG-4 part 10 (H.264) or MPEG-2. 720p MJPEG really needs a lot of
bandwidth for a somewhat decent quality. If you don't have the CPU or
hardware encoder sufficient for encoding, you could use a webcam with
built-in support for H.264 encoding such as Logitech C920 and others.

While MPEG-TS does not support MJPEG, RTP streams can. With some
limitations, Matroska can as well I think, but no UDP for the latter.
