While testing pyclutter and gstreamer I got a problem: take a look on
the attached file, lines 26 and 27. If you try to comment line 27 and
decomment line 26 the sample will not work, still
$ gst-launch-0.10 souphttpsrc
location=http://www.warwick.ac.uk/newwebcam/cgi-bin/webcam.pl?dummy=garb
! multipartdemux ! jpegdec ! ffmpegcolorspace ! xvimagesink
this is working.
What am I doing wrong?
