           Summary: mpeg2video decode path is broken
    Classification: Platform
           Product: GStreamer
           Version: 1.2.2
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major

I upgraded my gstreamer framework from 1.0.8 to 1.2.2 version. While performing
the sanity testing on the 1.2.2 version I found out that mpeg2 video decode
path is broken. I found the same issue in 1.2.1 version also. 

Initially I thought that the issue I found is similar to this
https://bugzilla.gnome.org/show_bug.cgi?id=721835 and applied the patch. But
the patch didn't help. 

Here is the input test file: http://goo.gl/O4cG3U
Pipeline to reproduce the issue:

gst-launch-1.0 filesrc location=airport_interview.ts ! decodebin ! video/x-raw
! filesink location=out.yuv

The output YUV is of 0 size. While same pipeline works perfectly fine in
gstreamer-1.0.8 version.

Please let me know if you require more information.
