Unfortunately we don't provide any 'demultiplexor' for Transport Streams, so
you can't do this using our software.

You could do this using our software by
1/ Creating a "MPEG2TransportStreamFromESSource" object
2/ Calling "addNewVideoSource()" on this
"MPEG2TransportStreamFromESSource" object, with the input MPEG-4 video source
as parameter, and with a "mpegVersion" parameter of 4.
(If the MPEG-4 video comes from a MPEG-4 Video Elementary
Stream file - *not* an AVI file - then you must first pass this file through a
"MPEG4VideoStreamFramer" object. Unfortunately, however, we don't support
reading from AVI files.)
3/ Creating a "FileSink" object (for the output Transport Stream file)
4/ Calling "startPlaying()" on the "FileSink" object, with the
"MPEG2TransportStreamFromESSource" object as source.
5/ Call "doEventLoop()" to enter the LIVE555 event loop (if you're not
already in it).
In short, if your input file is a MPEG-4 Video Elementary Stream file - *not*
an AVI file - then you could use the code for the
"testH264VideoToTransportStream" demo application (in the "testProgs"
directory), except that
- You would use "MPEG4VideoStreamFramer" rather than
"H264VideoStreamFramer".
- The "addNewVideoSource()" call would use a "mpegVersion" parameter of
4 rather than 5.
