WTF is that supposed to mean? If you want people to help you, you're going to
have to learn to write coherently.

Ditto.

Yes, probably, provided that the receivers can decode this OK. (A Transport
Stream is just that - a container for 'transporting' data, in any form.)
However, you will need to prepend each H.264 frame with 0x00 0x00 0x00 0x01 (if
those 4 bytes are not already there).

Perhaps you're not looking at a proper H.264-in-Transport-Stream file? If you
want to see a good one, look at
http://www.live555.com/liveMedia/public/h264-in-mp2t/
(BTW, the file there ("bipbop-gear1-all.ts"), along with its index file, can
also be used to test HTTP LIve Streaming.)

No! Note that "MPEG2TransportStreamFromPESSource" is a subclass of
"MPEG2TransportStreamMultiplexor".
I've already told you what you need to do: Feed your encoded H.264 data
directly to a "MPEG2TransportStreamFromESSource", by calling
"MPEG2TransportStreamFromESSource::addNewVideoSource()", with "mpegVersion" ==
5.
(Also, make sure that your H.264 data source generates proper presentation
times for each generated frame - by setting "fPresentationTime" properly.)
But, as I noted above, you may need to prepend each H.264 frame with 0x00 0x00
0x00 0x01 before feeding it to the "MPEG2TransportStreamFromESSource"
(Sigh... You're much too 'high maintenance' for my taste :-)
