[gst-devel] webcam & mpegps

[Nicolas Bertrand]

I make it working by 'forcing' ffmpecolorspace with a filter
gst-launch -v v4l2src ! ffmpegcolorspace!  video/x-raw-yuv, width=320, 
height=240, framerate=\(fraction\)30/1, format=\(fourcc\)I420 ! 
ffenc_mpeg2video ! mpegpsmux ! filesink location=test.mpg
