• Merge commit ’3176217c60ca7828712985092d9102d331ea4f3d’

  Merge commit ’3176217c60ca7828712985092d9102d331ea4f3d’
  * commit ’3176217c60ca7828712985092d9102d331ea4f3d’ :
  
    h264 : decouple h264_ps from the h264 decoder
  Main changes :
   a local GetBitContext is created for the various
  
    ff_h264_decode_seq_parameter_set() attempts
   just like the old code, remove_sps() is adjusted so it doesn’t remove
  
    the pps.
    Fixes decode with Ticket #631
  
    http://ffmpeg.org/pipermail/ffmpeg-user/attachments/20111108/dae58f17/attachment.mp4
  
    but see next point as well.
   ff_h264_update_thread_context() is updated to work even when SPS
  
    isn’t set as it breaks current skip_frame code. This makes sure we
  
    can still decode the sample from ticket #631 without the need for
  
    -flags2 +chunks. (Thanks to Michael)
   keep sps,pps_ref pointers that stay alive even when the active
  
    pps/sps get removed from the available lists (patch by michaelni with
  
    additionnal frees in ff_h264_free_context() from mateo)
   added a check on sps in avpriv_h264_has_num_reorder_frames() to fix
  
    crashes with mpegts_with_dvbsubs.ts from Ticket #4074
  
    http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket4074/mpegts_with_dvbsubs.ts
   in h264_parser.c:h264_parse(), after the ff_h264_decode_extradata() is
  
    called, the pps and sps from the local parser context are updated with
  
    the pps and sps from the used h264context. This fixes fate-flv-demux.
   in h264_slice.c, "PPS changed between slices" error is not triggered
  
    anymore in one condition as it makes fate-h264-xavc-4389 fails with
  
    THREADS=N (Thanks to Michael)
