[vlc-devel] [PATCH] fix video playback on contextes with width and height differing from coded_width and coded_height

[Vittorio Giovara]

 This patch is needed when either container or bitstream impose some limitation on the final video size. Apparently it exposes a little problem with OSD in which text is rendered with the display aspect ratio instead of the orignal one. I'm not sure this problem is related to this patch but I can look at it I'm given some pointers.
 Also this brings a nice "Display resolution" entry in Codec Information.
 Thanks to courmisch for helping me with this contribution.
