G.726 streaming using MPEG-TS Muxer

[Chuck Crisler]

You don't need the RTP with the MP2T, they are redundant. Just route the
encoder output to the MPEGTSMUX and then UDPSINK. You may need a queue or
ffmpegcolorspace, but other than that it is simple. MP2T can multiplex
several stream types into one logical stream, so you should be able to
multiplex all three. However, from my experience, RTP is much more
efficient in terms of CPU usage and network bandwidht usage. You might want
to question the requirement to use MP2T.
