           Summary: gst-ffmpeg video decoders don't clear DELTA_UNIT
                    buffer flags after decoding the delta
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-ffmpeg
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: leio at gentoo.org
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


It seems that most or all gst-ffmpeg video decoders are passing buffers
downstream with the GST_BUFFER_FLAG_DELTA_UNIT flag set on most buffers, and
only a few don't have that flag set - probably those where keyframes happened
in the coded buffers.
I believe that because the buffers presumably contain raw decoded data of full
frames, none of them should be having the DELTA_UNIT flag set anymore once
passed on downstream.
