           Summary: [h264parse] Reduce latency and cpu usage for
                    packetized input
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: bilboed at gmail.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


When the input is packetized (stream-format=avc), we know the size of the NALU.
We can therefore avoid:
* Expensive code for looking for the next start code (we already know the size)
* Extra latency (we don't need to wait for the next packet)
