I&#39;ve been working with gstreamer in Debain Wheezy testing, I don&#39;t think ximagesink is working, although the rest of gstreamer seems to work. <br><br>For example this script:<br>gst-launch-0.10 dv1394src num-buffers=500 ! dvdemux ! dvdec ! ffmpegcolorspace ! x264enc ! matroskamux ! filesink location=video.mkv<br>
<br>Creates a file just fine, <br><br>If I want to output the stream to the screen (which is a very similar script):<br>gst-launch-0.10 -v dv1394src ! dvdemux ! dvdec ! ffmpegcolorspace ! ximagesink<br><br>I get:<br>Setting pipeline to PAUSED ...<br>
