Hi,

I would to play a raw uncompressed video sent via RTP packets to PC. For
this, I use gstreamer 1.0 pipeline as:

gst-launch-1.0 *udpsrc* port="5200" caps = "application/x-rtp,
media=(string)video, clock-rate=(int)90000,
encoding-name=(string)RAW,sampling=(string)YCbCr-4:2:2, depth=(string)8,
width=(string)720, height=(string)576, colorimetry=(string)BT601-5,
payload=(int)96" ! *rtpvrawdepay* ! *autovideosink*

on Win7 and bandwidth for RTP packets is 170 Mbs. At first, playing the
stream is well but the problem is that RAM usage of system is increased
gradually and after few minutes it gets all free spaces on the RAM and from
this point the video playback will be jerky. Is there a mistake in the
pipeline options? If not, How can I fix this annoying problem?

Regards,
Mahdi
