            Bug ID: 749058
           Summary: Sending large video frames over RTSP loses some data
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: All
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: documentation
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: vivia at ahiru.eu
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

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"
