            Bug ID: 771707
           Summary: gst-libav: h264 variant itu, regression from 0.10
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-libav
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: lists at svrinformatica.it
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

I have an avi with h264 variant itu, here are the caps:

video/x-h264, variant=(string)itu, framerate=(fraction)120/1, width=(int)320,
height=(int)240,
codec_data=(buffer)2000000127644014ac2b40a0fd8088000003000800000301e42000000128ee1f2c0000000000000000000000000000000000

this file works fine in 0.10 but in 1.0 give not negotiated, in 0.10 ffdec_h264
show sink caps as:

SINK template: 'sink'
    Availability: Always
    Capabilities:
      video/x-h264
                  width: [ 16, 4096 ]
                 height: [ 16, 4096 ]
              framerate: [ 0/1, 2147483647/1 ]

while in 1.0 the format are restricted:

SINK template: 'sink'
    Availability: Always
    Capabilities:
      video/x-h264
              alignment: au
          stream-format: { avc, byte-stream }


if I change avdec_h264 so that gst-inspect shows this:

SINK template: 'sink'
    Availability: Always
    Capabilities:
      video/x-h264

then the file plays fine,

is this acceptable? Do you have other suggestions for a better patch?
