autovideosink does not work in native Windows machine for RTP stream but works in VM

[Rigamonti Roberto]

Dear Tim,


I've managed to do the tests you've suggested (sorry for the delay, but the emitter is remote (>300km) and I have to wait for someone to turn it on for me...).

Using queue after udpsrc this is what I get: https://ibb.co/hBntcxg

Increasing the debug level, I get:

When using an rtpjitterbuffer, things seem to improve a bit (in the sense that at least gstreamer does not halt), but I'm still unable to get any image :(

Do you have any further test I could try?
Thanks a lot in advance and have a nice day!
Rob

What do you mean by "works perfectly" here? That it doesn't complain or
error out, or that the resulting mp4 file plays just fine afterwards?

It appears there's a problem with packet loss or reordered packets
here. Maybe nvh265dec has a start-up delay that blocks the udpsrc for a
bit too long (that's just speculation).

Have you tried putting a queue after udpsrc, like

 udpsrc ! queue max-size-time=0 max-size-buffers=0 max-size-bytes=0

or even better an rtpjitterbuffer like

 udpsrc ! rtpjitterbuffer latency=100 ! ..

Cheers
 Tim
