Encoding format string

[amindfv at mailbox.org]

Hi Thibault - I tried the encoding string you advised but I still see a similar error:

    $ ges-launch-1.0 --track-types=video +clip /home/foo/bar0.MOV inpoint=16.0 duration=2.0 +clip /home/foo/bar1.MOV inpoint=15.0 duration=3.0 --outputuri file:///home/foo/out.mp4 --format 'video/quicktime,variant=iso:video/x-raw,width=4096,height=2160->video/x-h264|element-properties,target-bitrate=200000'

    [...]

    ERROR from element qtdemux27: Internal data stream error./>

    Debugging info: ../gst/isomp4/qtdemux.c(6545): gst_qtdemux_loop (): /GESPipeline:gespipeline0/GESTimeline:gestimeline0/GESVideoTrack:gesvideotrack0/NleComposition:video_nlecomposition0/GstBin:current-bin/NleSource:GESVideoUriSource:nlesource1/GstBin:videosrcbin/GstURIDecodeBin:uridecodebin1/GstDecodeBin:decodebin56/GstQTDemux:qtdemux27:
    streaming stopped, reason not-negotiated (-4)

Any help would be very appreciated - I'm on the last day of a later deadline (first one missed) and the output file is incrediby low-quality at the moment.

Thanks!
Tom
