            Bug ID: 788595
           Summary: h264parse: Maybe break stream further rather then
                    fixing it
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal

     GNOME version: ---

As found with this file in bug #787795, with the following FLV file:

https://bugzilla.gnome.org/attachment.cgi?id=360317

h264parse turns a slightly broken stream into an un-playable stream. As an
example, the display video will be gray with the parser:

filesrc location=test.flv ! flvdemux ! h264parse ! avdec_h264 ! autovideosink

But looks fine without:

filesrc location=/tmp/test.flv ! flvdemux ! video/x-h264,alignment=au !
avdec_h264 ! autovideosink
