mplex issue

Hello All !
I am starting to play with gstreamer as a replacement for many tools I used for a while. As my first post on this list I would like to thank and congratulate you all for this amazing software ! I hope this is the right place for asking end-user/developper questions ... I have an issue with mplex while trying to extract a video and audio from a DVD and put them into a single mpeg file, without any transcoding. Here is the gst-launch pipeline I use : gst-launch -v dvdreadsrc ! dvddemux name=demuxer demuxer.current_audio ! queue ! mplex name=muxer ! filesink location=test.mpeg demuxer.current_video ! queue ! muxer. The pipeline is in preroll status but never goes to playing : [chicha@grogro Bureau]$ LC_ALL=C gst-launch -v dvdreadsrc ! dvddemux name=demuxer demuxer.current_audio ! queue ! mplex name=muxer ! filesink location=test.mpeg demuxer.current_video ! queue ! muxer. (gst-launch-0.10:2396): GLib-WARNING **: g_set_prgname() called multiple times Setting pipeline to PAUSED ... libdvdread: Using libdvdcss version 1.2.10 for DVD access libdvdread: Attempting to retrieve all CSS keys libdvdread: This can take a _long_ time, please be patient libdvdread: Get key for /VIDEO_TS/VIDEO_TS.VOB at 0x00000157 libdvdread: Elapsed time 0 libdvdread: Get key for /VIDEO_TS/VTS_01_0.VOB at 0x000001d9 libdvdread: Elapsed time 0 libdvdread: Get key for /VIDEO_TS/VTS_01_1.VOB at 0x0001350e libdvdread: Elapsed time 0 ...... libdvdread: Found 12 VTS's libdvdread: Elapsed time 0 Pipeline is PREROLLING ... /GstPipeline:pipeline0/GstDVDDemux:demuxer.GstPad:current_video: caps = video/mpeg, mpegversion=(int)2, systemstream=(boolean)false /GstPipeline:pipeline0/GstDVDDemux:demuxer.GstPad:current_audio: caps = audio/x-ac3 /GstPipeline:pipeline0/GstDVDDemux:demuxer.GstPad:current_subpicture: caps = video/x-dvd-subpicture /GstPipeline:pipeline0/GstDVDDemux:demuxer.GstPad:sink: caps = video/mpeg, mpegversion=(int)2, systemstream=(boolean)true /GstPipeline:pipeline0/GstQueue:queue1.GstPad:sink: caps = video/mpeg, mpegversion=(int)2, systemstream=(boolean)false /GstPipeline:pipeline0/GstQueue:queue1.GstPad:src: caps = video/mpeg, mpegversion=(int)2, systemstream=(boolean)false /GstPipeline:pipeline0/GstMplex:muxer.GstPad:src: caps = video/mpeg, systemstream=(boolean)true /GstPipeline:pipeline0/GstMplex:muxer.GstPad:video_0: caps = video/mpeg, mpegversion=(int)2, systemstream=(boolean)false /GstPipeline:pipeline0/GstQueue:queue0.GstPad:sink: caps = audio/x-ac3 /GstPipeline:pipeline0/GstQueue:queue0.GstPad:src: caps = audio/x-ac3 /GstPipeline:pipeline0/GstMplex:muxer.GstPad:audio_0: caps = audio/x-ac3 What I do not understand is that when I extract just the video or just the audio it works. Also playing the dvd sound + video to a pulsesink + xvimagesink works like a charm. I am sure I am missing something, but what ? Thank you very much for your help !

IIRC, the mplex backend library performs some moderately large initial (audio?) buffering, which might cause a deadlock. Have you already tried setting some larger limits on the queue's (e.g. queue max-size-buffers=0 max-size-bytes=0 max-size-time=4000000000). There is a more or less cryptic comment regarding this in the mplex element documentation.

Thank you Mark for your answer.
I tried to use the queue settings below. It some how worked since I finally went in playing mode but I quickly got some mplex errors : Too many frame drops -exiting. Some research on the web mention bit rate issues. I am going to look deeper into this issue, but if any body has an idea thank you in advance for your help !
