 Summary of the bug:
 In reference to bug #2050

 The following clip:
  http://www.avenard.org/files/media/mediatest/11159%20HD-PVR%20sample.mpg

 Presents video corruptions when using VDPAU, where playback devolves into
 a weird backward-and-forward stuttering, with frames being displayed out
 of order

 git bisect point bfca35114ae174bbabd88526379d95d4022a98b1 as the commit
 introducing the regression:
 {{{
 commit bfca35114ae174bbabd88526379d95d4022a98b1
 Author: Michael Niedermayer <michaelni at gmx.at>
 Date:   Wed Nov 16 23:58:06 2011 +0100

     h264: rewrite has_b_frame calculation code,
     the previous implementation was too buggy.

     Signed-off-by: Michael Niedermayer <michaelni at gmx.at>
 }}}

 Reversal of that commit against release/1.0 is available at:

 Issue also occurs on master.
