Hi Wim Thanks for the reply. 1. UDP: I executed the syntax you mentioned: gst-launch-0.10 -v filesrc location=foreman_422_vga._swap.yuv ! TIVidenc1 codecName=mpeg4enc engineName=encode contiguousInputFrame=FALSE iColorSpace=UYVY resolution=640x480 ! rtpmp4vpay ! udpsink The output is: Setting pipeline to PAUSED ... Pipeline is PREROLLING ... /GstPipeline:pipeline0/GstTIVidenc1:tividenc10.GstPad:src: caps = video/mpeg, mpegversion=(int)4, framerate=(fraction)30000/1001, width=(int)640, height=(int)480 /GstPipeline:pipeline0/GstRtpMP4VPay:rtpmp4vpay0.GstPad:sink: caps = video/mpeg, mpegversion=(int)4, framerate=(fraction)30000/1001, width=(int)640, height=(int)480 Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock It seems to me that the problem lies with the rtpmp4vpay element. It seems it is unable to allocate proper caps for the source pad. I have also attached the GST_DEBUG=3 output. I am currently using gst-plugins-good version 0.10.10. Should I upgrade it??? 2. RTSP: I used the updated version of gst-rtsp-server (with your today's patch), and I used the following syntax: ./test-launch "( filesrc location=foreman_422_vga._swap.yuv ! TIVidenc1 codecName=mpeg4enc engineName=encode contiguousInputFrame=FALSE iColorSpace=UYVY resolution=640x480 ! rtpmp4vpay pt=96 name=pay0 )" And I got this output (has errors): ** Message: listening on port 8554 ** Message: added new client 0x16cf0 ip 172.24.136.232:28426 ** Message: attaching to context 0x13e18 RTSP request message 0x8e2b4 request line: method: 'OPTIONS' uri: 'rtsp://172.24.190.40:8554/test' version: '1.0' headers: key: 'CSeq', value: '41' key: 'User-Agent', value: 'VLC media player (LIVE555 Streaming Media v2009.03.22)' body: ** Message: client 0x16cf0: received a request RTSP response message 0xbefff9f8 status line: code: '200' reason: 'OK' version: '1.0' headers: key: 'CSeq', value: '41' key: 'Public', value: 'OPTIONS, DESCRIBE, GET_PARAMETER, PAUSE, PLAY, SETUP, SET_PARAMETER, TEARDOWN' key: 'Server', value: 'GStreamer RTSP server' body: length 0 ** Message: client 0x16cf0: sent a message with cseq 41 RTSP request message 0x8e2b4 request line: method: 'DESCRIBE' uri: 'rtsp://172.24.190.40:8554/test' version: '1.0' headers: key: 'CSeq', value: '42' key: 'Accept', value: 'application/sdp' key: 'User-Agent', value: 'VLC media player (LIVE555 Streaming Media v2009.03.22)' body: ** Message: client 0x16cf0: received a request ** Message: found media 0x3e7c0 for url abspath /test ** Message: found stream 0 with payloader 0xce0d8 ** Message: constructed media 0xcd820 for url /test ** Message: preparing media 0xcd820 ** Message: enter mainloop ** Message: 0xcd820: got message type async-done ** Message: position query failed ** Message: duration query failed ** Message: stats: position 0:00:00.000000000, duration 99:99:99.999999999 ** Message: object 0xcd820 is prerolled ** (lt-test-launch:1173): WARNING **: ignoring stream 0 without media type RTSP response message 0xbefff9d8 status line: code: '200' reason: 'OK' version: '1.0' headers: key: 'CSeq', value: '42' key: 'Content-Type', value: 'application/sdp' key: 'Content-Base', value: 'rtsp://172.24.190.40:8554/test/' key: 'Server', value: 'GStreamer RTSP server' body: length 170 00000000 (0x107858): 76 3d 30 0d 0a 6f 3d 2d 20 31 31 38 38 33 34 30 v=0..o=- 1188340 00000010 (0x107868): 36 35 36 31 38 30 38 38 33 20 31 20 49 4e 20 49 656180883 1 IN I 00000020 (0x107878): 50 34 20 31 32 37 2e 30 2e 30 2e 31 0d 0a 73 3d P4 127.0.0.1..s= 00000030 (0x107888): 53 65 73 73 69 6f 6e 20 73 74 72 65 61 6d 65 64 Session streamed 00000040 (0x107898): 20 77 69 74 68 20 47 53 74 72 65 61 6d 65 72 0d with GStreamer. 00000050 (0x1078a8): 0a 69 3d 72 74 73 70 2d 73 65 72 76 65 72 0d 0a .i=rtsp-server.. 00000060 (0x1078b8): 65 3d 4e 4f 4e 45 0d 0a 74 3d 30 20 30 0d 0a 61 e=NONE..t=0 0..a 00000070 (0x1078c8): 3d 74 6f 6f 6c 3a 47 53 74 72 65 61 6d 65 72 0d =tool:GStreamer. 00000080 (0x1078d8): 0a 61 3d 74 79 70 65 3a 62 72 6f 61 64 63 61 73 .a=type:broadcas 00000090 (0x1078e8): 74 0d 0a 61 3d 72 61 6e 67 65 3a 6e 70 74 3d 30 t..a=range:npt=0 000000a0 (0x1078f8): 2e 30 30 30 30 30 30 2d 0d 0a .000000-.. ** Message: client 0x16cf0: sent a message with cseq 42 ** Message: added new client 0xe9350 ip 172.24.136.232:29194 ** Message: attaching to context 0x13e18 ** Message: client 0x16cf0: connection closed ** Message: finalize client 0x16cf0 ** Message: finalize media 0xcd820 Segmentation fault I have also attached the output corresponding to GST_DEBUG=2 and GST_DEBUG=3. I think the error in both the case lies in the rtpmp4vpay. Am I right??? Thanks in advance.

This is likely because the encoder did not set proper caps on the output buffers. Check this: gst-launch-0.10 -v filesrc location=foreman_422_vga._swap.yuv ! TIVidenc1 codecName=mpeg4enc engineName=encode contiguousInputFrame=FALSE iColorSpace=UYVY resolution=640x480 ! rtpmp4vpay ! udpsink And see what caps (if any) are set on udpsink. also, I solved the warnings in the rtsp server by ignoring streams that don't have a correct type.
