[gst-devel] How to save a stream from a network into a file

[Zelalem Sintayehu]

Hi, I was trying to transfer video and audio using network. I used teh examples from the net to do that and succeeded. But now I wanted to save the stream into file and faced with some problem. Please look at the following command:

gst-launch-0.10 udpsrc port=5000 caps="application/x-rtp, media=(string)video,clock-rate=(int)90000, encoding-name=(string)H263-1998" num-buffers=5000 ! queue ! rtph263pdepay ! ffdec_h263 ! xvimagesink   ----- this is what i used to accept and display a video stream. 

So, to save the stream into a file I changed the last two elements (the ffmpeg decoder and xvimake sink). I thought that since the packet coming from the other machine is already encoded in h263p codec, replacing these two elements  with the following elements would solve my problem: I used these elments: avimux ! filesink location=testnet.avi . That is, i connected the rtph263pdepay element to the avimux element and to the file sink element sequentially as follows. 

 gst-launch-0.10 udpsrc port=5000 caps="application/x-rtp, media=(string)video,clock-rate=(int)90000, encoding-name=(string)H263-1998" num-buffers=5000 ! queue ! rtph263pdepay ! avimux ! filesink location=test.avi

But I got an error, that says: streaming task paused, reason not-negotiated (-4)

Please help me on how I can save a stream. 

Thank you.
