[gst-devel] Problem with changing command line command to code

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
num-buffers=5000 ! queue ! rtph263pdepay !
'video/x-h263,width=320,height=240,framerate=(fraction)25/1' ! queue} !
mux.video_0 {udpsrc port=5002
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.
