[vlc-devel] [PATCH] Properly fix HDTV height for H.264 streams

[Marian Ďurkovič]

Hi,

  attached please find the patch which ensures proper fixing for
broken H.264 HDTV-1080 streams. Unfortunately, even with H.264,
some broadcasters still transmit 1088 lines :-(

   With kind regards,

         M.
