Ok, perhaps I am just misunderstanding the purpose of no-more-pads.
I am using it to determine that both video and audio pads have been created, so
I can build the rest of the pipeline.
What I'm doing as a work-around is to listen on pad-added, determine for every
pad if it's a video our audio pad, and continue when I have both. That is a lot
more code than just these two lines in the no-more-pads handler:
gst_element_link_pads(qtdemux, "audio_00", fakesink, "sink");
gst_element_link_pads(qtdemux, "video_00", queue2, "sink");
> The thing is that the element cannot know when there are no more streams in the

Out of curiosity... if that is the case, then how can qtdemux and dvddemux
signal no-more-pads? Does a VOB file have an index that tells you exactly how
many audio and subpicture streams are available in the PS? Is
QuickTime/MPEG-4's system different from the MPEG-TS/PS stream concept?
