I am using the qtdemux and then I put the output into my onboard decoder.  However it is failing to find start codes in the data. > I checked by running qtdemux on my PC (FC10) by running the following: > gst-launch filesrc location=term.mov ! qtdemux name=demux  demux.audio_00 ! queue ! fakesink   demux.video_00 ! queue ! filesink location=gstreamer.h264 > qtdemux doesn't output an H.264 elementary stream, which is where you're having problems. Additional headers needed to initialise your decoder will be in the "codec_info" attribute in the caps. Depending on how your decoder is structured, perhaps you can supply this directly, or perhaps you need to rewrite the stream using that data to be a raw elementary stream.
