[gst-devel] saving rtsp stream tracks

[gather bzbz]

Hi, I try to use gstreamer to receive rtsp stream to files. The stream contains a track1 for audio and track2 for video. VLC works very well with the stream. When I use the following command pipeline
" gst-launch rtspsrc location=rtsp://<ip> debug=true ! fakesink ", I can see that gstreamer actually gets the SDP part right. See following info.

How can I save the audio track1 to a file and video track2 to another so I can do some post-processings? Thanks a lot for your help!!!
