Our RIST implementation currently expect static payload only. All TV appliance
only implement MPEG TS payloaded as RTP (x265enc ! mpegtsmux ! rtpmp2tpay ! ..).
The rtpsrc element supports passing encoding-name or caps to let it use dynamic
payload type, feel free to port this code into ristsrc. Have been on my todo for
a while. Note that there is currently no activity around implementing the new
profiles. This implementation is perhaps less relevant since the arrival of
https://code.videolan.org/rist/librist . That being said, the result we had with
the GStreamer RTP stack was in general of very good quality compare to vendor
stack during interop testing. There is few optimization around multi-cast
retransmission missing, but otherwise it's quite compliant to the simple
