Auto plugger for RTP Depay

[josh]

You are correct decodebin works but only if you set the specific caps i.e.

gst-launch-1.0 -v udpsrc port=10000 !
application/x-rtp,media=video,encoding-name=H264,clock-rate=90000,payload=96
! rtpjitterbuffer ! decodebin ! videoconvert ! queue max-size-buffers=3 !
autovideosink

However if I don't know whether it's H264 or H265 how do i set the caps? 

Using parsebin like this doesn't work...

gst-launch-1.0 -v udpsrc port=10000 !
application/x-rtp,media=video,clock-rate=90000,payload=96 ! rtpjitterbuffer
! parsebin ! decodebin ! videoconvert ! queue max-size-buffers=3 !
autovideosink

It gives fails with...
