I am working on receiving an udpsrc stream and publishing it as an rtsp stream. This gst-launch string works just fine to receive the stream:<div><br></div><div>gst-launch-0.10 -v udpsrc port=5000 caps="application/x-rtp, media=\(string\)video, clock-rate=\(int\)90000, encoding-name=\(string\)H264, payload=\(int\)96, ssrc=\(guint\)2396357661, clock-base=\(guint\)2297066863, seqnum-base=\(guint\)49439" ! rtph264depay ! decodebin ! ffmpegcolorspace ! videoscale ! xvimagesink sync=false</div> <div><br></div><div>but when I try to take that pipeline and put it into a test-launch, I get complaints about not being able to set the caps on udpsrc to application/x-rtp.</div><div><br></div><div>Like this:</div><div><br> </div><div><div>./test-launch "( udpsrc port=5000 caps="application/x-rtp, media=\(string\)video, clock-rate=\(int\)90000, encoding-name=\(string\)H264, payload=\(int\)96, ssrc=\(guint\)2396357661, clock-base=\(guint\)2297066863, seqnum-base=\(guint\)49439" ! rtph264depay ! decodebin ! ffmpegcolorspace ! videoscale ! x264enc ! rtph264pay name-pay0 pt=96 )"</div> <div><br></div><div>** (lt-test-launch:20772): CRITICAL **: could not parse launch syntax (( udpsrc port=5000 caps=application/x-rtp,): could not set property "caps" in element "udpsrc0" to "application/x-rtp,"</div> <div><br></div><div>** (lt-test-launch:20772): CRITICAL **: could not create element</div></div><div><br></div><div>I could not find any examples of udpsrc in a test-launch line or udpsrc in a gst-rtsp-server 'c' program so I am not at all sure if what I am trying to do is valid.</div> <div><br></div><div>Morris</div>
