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: https://bugzilla.gnome.org/show_bug.cgi?id=762509 https://bugzilla.gnome.org/show_bug.cgi?id=795783
