Video output from gstreamer getting stuck/green

[manickam palaniappan]

Typically I use a pipeline cmd as below, but half of the time when I open the stream url that gets generated by gstreamer, I find that the output video gets stuck either immediately or after some 2 minutes after opening.

And at certain attempts, the initial output for nearly 30 seconds is either all green or all gray. What could be going wrong here ? FYI, the input feed is 25 frames per sec, with a resolution of 320x280


gst-launch-1.0 rtspsrc location=rtsp://xxx.xxx.xxx/videoSub ! 'application/x-rtp,media=video' ! decodebin ! videoconvert ! deinterlace ! queue max-size-buffers=3 silent=true  ! videoconvert qos=true ! videoscale qos=true  ! videobalance ! 'video/x-raw,width=176,height=144' ! videorate ! 'video/x-raw,framerate=9/1' ! videoconvert ! 'video/x-raw,width=176,height=144,format=RGB' ! facedetect profile=/opencv-2.4.8/data/haarcascades/haarcascade_frontalface_default.xml ! faceblur profile=/opencv-2.4.8/data/haarcascades/haarcascade_frontalface_default.xml !  videoconvert ! x264enc ! 'video/x-h264,profile=baseline' ! rtph264pay ! udpsink port=5000

From gst-rtsp-server library examples

./test-launch '( udpsrc port=5000 ! capsfilter caps="application/x-rtp,payload=96,clock-rate=90000,encoding-name=H264,media=video" name=pay0 )' 8554

Pls help.

Thanks,
Manickam
