request Sink pad of your avimux, link it to your audiobin. use gst-inspect "ELEMENT_TO_VIEW" to view your element pads, some of them aren't always available. some are dynamic. Hope that helps. <div class="gmail_quote">On Tue, Jun 23, 2009 at 1:00 PM, Zelalem Sintayehu <<a href="mailto:zelalems@hotmail.com">zelalems@hotmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div> Hi all, I had a command line command that copies video streams from a network into a file. When I try to change it to a code I face with problem. There is no error and the file is created but the content of the file is empty. I have also used sync=FALSE for the filesink element. I used two bins one for the audio and another for the video and then put the two bins and the avimux and filesink in the pipeline and started the pipepline. I even checked the state of the pipeline and it is in running state, but the file is empty. Pease help me. The following is the case: I wanted to change the following into a code: gst-launch-0.10 -v avimux name=mux ! filesink location=videoandaudio.avi sync=true {udpsrc port=5000 caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H263-1998" num-buffers=5000 ! queue ! rtph263pdepay ! 'video/x-h263,width=320,height=240,framerate=(fraction)25/1' ! queue} ! mux.video_0 {udpsrc port=5002 caps="application/x-rtp,media=(string)audio,payload=(int)96, rate=(int)8000, encoding-name=(string)PCMA" ! queue ! rtppcmadepay ! 'audio/x-alaw, rate=(int)8000, channels=(int)1' ! queue} ! mux.audio_0; And the following is what I did: gst_bin_add_many (GST_BIN (audbin), udpsource_audio, queue_audio, pcmadepay, NULL); gst_bin_add_many (GST_BIN (vidbin), udpsource_video, queue_video_1, h263depay, NULL); gst_bin_add_many (GST_BIN (pipeline), vidbin, audbin, avimuxer, filedes, NULL); gst_element_link_many (udpsource_video, queue_video_1, h263depay, NULL); gboolean link_ok_video = gst_element_link_filtered (h263depay, avimuxer, caps_video_2); gst_element_link_many (udpsource_audio, queue_audio, pcmadepay, NULL); gboolean link_ok_audio = gst_element_link_filtered (pcmadepay, avimuxer, caps_audio_2); gst_element_link_many (avimuxer, filedes, NULL); gboolean pipstate=gst_element_set_state (GST_ELEMENT (pipeline), GST_STATE_PLAYING); Thank you. - Zelalem S. <hr>Invite your mail contacts to join your friends list with Windows Live Spaces.
