            Bug ID: 788563
           Summary: rtph264depay frequently introduces frame drops.
    Classification: Platform
           Product: GStreamer
           Version: 1.12.0
                OS: Windows
            Status: NEW
          Severity: major
          Priority: Normal
         Component: gst-plugins-good

     GNOME version: ---

Displaying a stream from an RTP h264 source, gstreamer frequently displays
video artifacts as if it drops frames. The same issue is not noticeable using
other (libav based) players.

gst-launch periodically throws the error:

WARNING: from element /GstPipeline:pipeline0/GstRtpH264Depay:rtph264depay0:
Could not decode stream.
Additional debug info:
gstrtpbasedepayload.c(466): gst_rtp_base_depayload_handle_buffer ():
/GstPipeline:pipeline0/GstRtpH264Depay:rtph264depay0:
Received invalid RTP payload, dropping

Tested with the following pipeline, with identical results:

    gst-launch-1.0 udpsrc port=15005 caps=application/x-rtp ! rtph264depay !
queue ! avdec_h264 ! videoconvert ! queue ! autovideosink sync=false
    gst-launch-1.0 udpsrc port=15005 caps=application/x-rtp ! rtph264depay !
queue ! avdec_h264 ! queue ! videoconvert ! autovideosink sync=false
    gst-launch-1.0 udpsrc port=15005 caps=application/x-rtp ! rtph264depay !
avdec_h264 ! videoconvert ! autovideosink sync=false
