[vlc-devel] [PATCH] Support for rotated MP4 Movies (bug #2882)

[Matthias Keiser]

What follows is a series of patches so that rotated mp4's are correctly displayed. I tested it with the files found here:

http://streams.videolan.org/issues/2882/

Note: These patches currently only work if the mp4 gets demuxed with the MP4 demuxer or with FFMpeg libavformat, but NOT with libav libavformat (because it doesn't set the rotation information). Since currently libav is the default, this means you might have to make sure that it plays via the MP4 demuxer, which in turn means you probably have to download the examples to disk, and not simply stream them (else MP4 demuxer will bail out).
