           Summary: Fail to negotiate pipeline using rtph263ppay,
                    avenc_h263p and a fixed caps filter
    Classification: Platform
           Product: GStreamer
           Version: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-libav
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: gdesmott at gnome.org
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


The following pipeline works "gst-launch-1.0 videotestsrc ! avenc_h263p !
rtph263ppay ! udpsink" but this one doesn't:

$ gst-launch-1.0 -v videotestsrc ! avenc_h263p ! rtph263ppay !
application/x-rtp ! udpsink 
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

Setting pipeline to NULL ...

/GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0.GstPad:src: caps = NULL
Freeing pipeline ...

In the first pipeline, gst_ffmpeg_caps_with_codecid() is called with
"video/x-h263, variant=(string)itu" (1 struct) and so everything works fine.

But in the second one, it's called with "video/x-h263, variant=(string)itu,
h263version=(string)h263, annex-f=(boolean)false, annex-i=(boolean)false,
annex-j=(boolean)false, annex-t=(boolean)false; video/x-h263,
variant=(string)itu, h263version=(string)h263" (2 structs); this function only
use the first structure and so it fails to negotiate.
