save an rtp stream: aviheader issue
 
|
Hi,
I'm trying to save an rtp stream with the following pipeline: gst-launch-0.10 -e -v udpsrc port=6000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)JPEG, payload=(int)26" ! .recv_rtp_sink_0 gstrtpbin ! rtpjpegdepay ! queue ! avimux ! filesink location=test-gst.avi the resulting file miss some information in the headers, if I try to see it with mplayer I have this error: Playing test-gst.avi. AVI file format detected. [aviheader] Video stream found, -vid 0 AVI: No audio stream found -> no sound. VIDEO: [MJPG] 352x288 24bpp 0.000 fps 0.0 kbps ( 0.0 kbyte/s) FPS not specified in the header or invalid, use the -fps option. No stream found. to see the stream I have to manually specify the fps: mplayer -fps 3 test-gst.avi works fine, using: gst-launch-0.10 playbin uri=file:///home/nicola/test-gst.avi the video is played very slow, what modifications I have to do to the above pipeline to generate a standard aviheader? thanks Nicola P.S.

I added a videorate element so this pipeline works:
gst-launch-0.10 -e -v udpsrc port=6000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)JPEG, payload=(int)26" ! .recv_rtp_sink_0 gstrtpbin ! rtpjpegdepay ! videorate ! image/jpeg, width=352, height=288, framerate=3/1 ! avimux ! filesink location=test-gst.avi but if I don't know the framerate or the framerate is variable how can I tell to gstreamer to autodetect these infos?

Hi.
Can you write the transmission pipeline? Which board are you using?

Hi,
wouldn't it be easier to save the stream with e.g. tcpdump and then convert it with something like (this is for h264 video only but is extensible to audio as well): gst-launch filesrc location=capture.pcap ! pcapparse src-port=3378 ! "application/x-rtp, payload=97" ! rtph264depay ! "video/x-h264, width=320, height=240, framerate=(fraction)30/1" ! avimux ! filesink location=test.avi the capture command should be something like: tcpdump -ietho -s0 -w capture.cap you've to check the udp port and payload type you're interested in by using wireshark, but some automation is possible anyway.
