It seems like we are on a good path. after I tried the pipeline: gst-launch-0.10 filesrc location=MY_MOVIE ! qtdemux name=t ! queue max-size-time=0 max-size-bytes=0 ! mpeg4dec ! MY_VIDEO_SINK t. ! queue ! faad ! alsasink (so I only give time and bytes for video side) the video and audio worked just fine. Unfortunately this trick does not work for the other decoder I have which decodes h264 videos. Even with the pipeline: gst-launch-0.10 filesrc location=MY_MOVIE ! qtdemux name=t ! queue max-size-time=0 max-size-bytes=0 ! h264dec ! MY_VIDEO_SINK t. ! queue ! faad ! alsasink The pipeline is stuck. This all has nothing to do with GST_FLOW_WRONG_STATE since this error pops up all the time after CTRL-C operation. Any idea why would h264 get stuck? Another question is if I am giving too much memory to gstreamer with max-size-time=0 max-size-bytes=0?

(b) high latency at the your video decoder (mpeg4dec). Hence the streaming thread is blocked & one of the sinks is not able to commit the state to PAUSED. (because it has not received a buffer yet). Yo can also set async=FALSE on the sinks and see. (not recommended) You can try disabling the the max time & max bytes properties of the queue. Try the following pipeline <div> gst-launch-0.10 filesrc location=MY_MOVIE ! qtdemux name=t ! queue </div>max-size-time=0 max-size-bytes=0 ! mpeg4dec ! MY_VIDEO_SINK t. ! queue max-size-time=0 max-size-bytes=0 ! faad ! alsasink -v Note that this will increase the mem usage.. and even more if u set max-size-buffers=0 as well. (queue without any limits!)
