qmlplayer2 output when using videotestsrc through an rtsp server
Using gstreamer 1.2.0 git master HEAD, When using an RTSP server, the stride
looks fine for:
gst-launch-1.0 playbin uri=192.168.232.62:8554/test
but incorrect for:
./qmlplayer2 192.168.232.62:8554/test
See attached image of qmlplayer2 output. I see the same incorrect stride for my
own H264 live source. A handful of non-live H.264 videos seem to work fine. The
included http big-buck-bunny example in qmlplayer2 also works fine.
For the RTSP server, I am using the gst-rtsp-server/examples/test-netclock.c
example with the launch line:
gst_rtsp_media_factory_set_launch (factory, "(videotestsrc pattern=19
is-live=true horizontal-speed=1 ! video/x-raw, framerate=(fraction)60/1,
height=(int)1000, width=(int)1000 ! x264enc ! rtph264pay name=pay0 pt=96 )");
