tsdemux & ffec_h264: ffmpeg :0:: non-existing PPS referenced

[Chuck Crisler]

The problem is in the server pipeline. It looks like you are generating
straight MP2T but your client is decoding MP2T encapsulated in RTP, which
gives the error. Since you seem to want to multiplex (mux) the audio and
video, use straight MP2T.  Your server pipeline might be ok. Your client
will be receiving something like application/x-MP2T (not sure of the exact
syntax), no payload, no ssrc, timestamp or seqno. Use the MP2T demuxer and
'T' for the audio and video. I use 0.10 so the element names have changed.
You will have to use gst-inspect | grep -i mp2t to find the proper element
name for the MP2T demuxer. There are examples of this but most are for
0.10, not the 1.x code.
