    msdk:dec: Add new propery to dump frames in decoded order · 54482a54
    Sreerenj Balachandran authored
    The new property "output-order" can be set to either "display" order
    which is the default where frames will be outputting in display order,
    or "decoded-order" which will be outputting the frames in decoded order.
    
    The "decoded order" output is generally useful for debugging. But there
    are few
    customers who use it for low-latency streaming. For eg if the customer
    already knows that the stream doesn't have b-frames (which means no
    algorithm requires for display order calculation), then they can use
    "decoded-order"
    output to skip some of the DPB logic to avoid the frame accumulation at
    start-up.
    
    The root cause of the above issue is a bit of unclarity in h264 spec +
    lazy implementation of many H264 encoders; This is well handled in
    gstreamer-vaapi using "low-latency" property:
