gstreamer x264enc matroskamux issue

[paul.praet at telenet.be]

I am trying to convert a DVD to mkv file with gstreamer. The pipeline I use is: 


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. (I cannot use dvdreadsrc because I get another error on the iso file) Unfortunately the pipeline does not go beyond prerolling. When I replace x264enc with for instance ffenc_mpeg4, then everything works fine.. Some people suggested adding byte-stream=1 to x264enc but it did not change anything.
