Description Vivia Nikolaidou 2015-05-07 09:01:50 UTC
I try playing back this pipeline using gst-play-1.0 :
./test-launch "videotestsrc pattern=snow ! video/x-raw,width=1920,height=1080 ! jpegenc quality=100 ! rtpjpegpay name=pay0"
and it doesn't play with UDP. TCP works (until it explodes), but it lags.

Trying some more pipelines that can send huge frames results to corrupted frames, e.g.
./test-launch "videotestsrc pattern=snow ! video/x-raw,width=1920,height=1080 ! avenc_mpeg2video bitrate=9900000 ! rtpmpvpay name=pay0"
./test-launch "videotestsrc pattern=snow ! video/x-raw,width=1920,height=1080 ! rtpvrawpay name=pay0"

What is the size of your udp send buffer? (check log)

You will have to make sure it's sufficiently large (ie. as large as possible).

Duplicate of bug #673794 IMHO, unless you have specific suggestions how to remedy this in gst-rtsp-server.

This might've become worse with the sendmmsg() changes btw, but I also think it's a duplicate of that other bug.
