            Bug ID: 104731
           Summary: UVD lockup on MPEG2 missing Field
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: bugzilla77 at free.fr

We have some broken MPEG2 samples causing lockup in UVD (not only, and also
crashing some libs).

At least happens with Radeon 6450 / UVD 3.

Content and not properly packetize and causes video players to send samples
containing reference to a missing previous iframe field.
