Description dizieg 2010-08-06 15:22:18 UTC 
For example it doesn't work with
startx=311
starty=433
endx=679
endy=700

and works with

startx=100
starty=100
endx=200
endy=200

Both parameter combinations work probably here. What exactly is the failure you get from using the first combination?

I am just creating app with gstreamer pipeline: ximagesrc ! ffmpegcolorspace ! queue ! videorate ! xvidenc ! avimux ! filesink and when I used first combination gstreamer created only empty avi file.

I use archlinux packages gstreamer(0.10.29-1) and base-plugins(0.10.29-1).

Are you sure this is an issue with ximagesrc and not just xvidenc not supporting 'odd' widths/heights?

I get this:


tpm@zingle:~/gst/git/gst-plugins-good/gst/avi$ GST_DEBUG=xvid*:5 gst-launch-0.10 ximagesrc startx=311 starty=433 endx=679 endy=700  ! ffmpegcolorspace ! queue ! videorate ! xvidenc ! fakesink -v

While it works fine with ffenc_mpeg.
