So the pipeline I am using is: gst-launch-0.10 filesrc location=MY_MOVIE ! qtdemux name=t ! queue ! mpeg4dec ! MY_VIDEO_SINK t. ! queue ! faad ! alsasink This pipeline will hang and after CTRL-C the mpeg4dec will show the message that is the result of calling gst_push_pad. This gst_push_pad will return GST_FLOW_WRONG_STATE. If I run gst-launch-0.10 filesrc location=MY_MOVIE ! qtdemux name=t ! queue ! mpeg4dec ! MY_VIDEO_SINK the video will play just fine If I run: gst-launch-0.10 filesrc location=MY_MOVIE ! qtdemux name=t ! queue ! faad ! alsasink the audio from the audio will play just fine. I am not sure which code would be helpful since I have a lot of it. Thanks for the GST_DEBUG info.

FLOW_WRONG_STATE is what you get when a pad is flushing, which may be normal (happens during a flushing seek, to make the old streaming thread stop) or because you forgot to set an element into PAUSED/PLAYING state (e.g. because you added it from a pad-added or new-decoded-pad callback or so). The GST_DEBUG=*:5 log might give you more information (just grep for wrong-state and read the lines before that).
