[gst-devel] save an rtp stream: aviheader issue

[Mailing List SVR]

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?
