H265 UDP streaming problem

[mp]

Hello!

I have a problem with streaming H.265 video on UDP as it works only when the
receiver starts listening BEFORE the sender starts streaming. It is the same
for MPEG-TS and RTP protocol. With H.264 there is no such problem.

Exemplary sender pipeline:
gst-launch-1.0 v4l2src device=/dev/video0 ! decodebin ! videoconvert !
"video/x-raw, format=(string)I420" ! x265enc name=encoder  ! 'video/x-h265,
stream-format=(string)byte-stream, alignment=(string)au' ! rtph265pay
mtu=1400 ! udpsink host=127.0.0.1 port=1234

Exemplary receiver pipeline:
gst-launch-1.0 -v udpsrc port=1234 do-timestamp=true !
application/x-rtp,encoding-name=H265,payload=96 ! rtph265depay ! h265parse !
queue ! avdec_h265 ! xvimagesink

Does anyone have any idea how to solve this problem?

Thanks, best regards,
Matevz
