The audio finishes almost 3 second ahead of the video. I even used the sync=true option for the filesink element, but the result is the same. So, I want to ask an advice on how to get a synchronized video file. The following is the source and destination commands that I used: Source commands: for the audio channel gst-launch-0.10 -v alsasrc ! queue ! audio/x-raw-int,rate=8000,channels=1,depth=8 ! audioconvert ! alawenc !  rtppcmapay ! queue ! udpsink port=5002 for the video channel; gst-launch v4l2src ! video/x-raw-rgb,width=320,height=240 ! queue ! videorate ! video/x-raw-rgb,rate=15/1 ! ffmpegcolorspace! ffenc_h263p ! rtph263ppay ! udpsink port=5000 Output command: 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; Do you think the result will be different if I use a different file container (like mp4) instead of avi?
