input-selector pixelation when changing active-pad on RTSP stream

[Peter Körner]

Hi

the input-selector will switch in the middle of the compressed h265
stream. I'd recommend decoding each of the two streams individually and
then feed tgem into a compositor element. there you can set the opacity
of one of the two streams to 1 and the oter to 0.

Something like

rtspsrc location=rtsp://10.64.0.5:554/stream0  is-live=true latency=0 !
  rtph265depay ! libde265dec ! mix.
rtspsrc location=rtsp://10.64.0.5:554/stream1  is-live=true latency=0 !
  rtph265depay ! libde265dec ! mix.
compositor name=mix ! x265enc ! rtph265pay name=pay0 pt=96
