Hi.

Thanks for the reply.
I have already checked out the pipeline before and used it to encode the video in m4v format. It works fine. I have looked into the errors and now I have fewer errors than before. The problem was that elements input-selector weren't installed.

Note: I have gst-rtsp-server-0.10.3 installed.

For the test-launch:
./test-launch --gst-debug-no-color --gst-debug=0 "( filesrc location=foreman_422_vga._swap.yuv ! TIVidenc1 codecName=mpeg4enc engineName=encode contiguousInputFrame=FALSE iColorSpace=UYVY resolution=640x480 ! rtpmp4vpay pt=96 name=pay0 )"

Output is: (GST_DEBUG=5)

Hi,

  Try to find out if it's in your launch pipeline first before sending it
through the RTSP server test-launch app.  For instance, do a quick RTP
session to a host using the same launch line to a linux/windows machine.  It
may help to narrow your problem as I'm not sure it's the RTSP server.  I
could be wrong though.
