title: gstreamer muxing with x264enc
body: <p>I am trying to convert a DVD to mkv file with gstreamer. The pipeline I use is:</p>
  
  <pre>
  gst-launch -evv multifilesrc location="VTS_01_%d.VOB" index=1 ! dvddemux name=demuxer \
   matroskamux name=mux ! filesink location=test.mkv \
   demuxer.current_video ! queue ! mpeg2dec ! x264enc ! mux. \
   demuxer.current_audio ! queue ! ffdec_ac3 ! lamemp3enc ! mux.
  </pre>
  
  <p>Unfortunately the pipeline does not go beyond prerolling. When I replace x264enc with for instance ffenc_mpeg4, then everything works fine..</p>
