Bug#757185: libavformat55: missing support for 3D video tags in mkv decoder

[Sebastian Reichel]

Package: libavformat55
Version: 6:10.3-1
Severity: wishlist
Tags: upstream
Control: affects -1 xbmc

Hi,

libav is missing support for 3D video tags in mkv files, which
cripples libav using applications to autodetect 3D video files.

If I understand the situation correctly there is support to pass along
the stereo_mode from the mkv container to video applications in ffmpeg
[0], but the same support is missing in libav [1]. ffmpeg's support
seems to be originating from commits [3] and [4].

Please add support for the stereo mode tag in Debian's (and possibly
upstream's) libav.
