[gst-devel] muxing and filesink

[sudarshan bisht]

In your first pipeline it should be udpsink , not udpsrc.


Another thing is that you are not properly setting up rtp packets of encoded
data.
So I think your pipelines should look like this;


gst-launch videotestsrc ! videoscale ! videorate !
video/x-raw-yuv,width=640,height=480,framerate=25/1 ! ffmpegcolorspace !
ffenc_mpeg4   ! rtpmp4vpay  ! udpsink host=127.0.0.1 port=5000

gst-launch  udpsrc port=5000   !
application/x-rtp,media=video,payload=100,clock-rate=100000000,encoding-name=MP4V-ES
! rtpmp4vdepay  !
video/mpeg,width=640,height=480,framerate=25/1,mpegversion=4,systemstream=false
! avimux  ! filesink location=test.avi

And I could  play this file using gst-launch playbin
uri=file:///home/maemo/test.avi
