           Summary: missing support for 3D video tags in matroska decoder
           Product: Libav
           Version: 10
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: libavformat
        AssignedTo: bugzilla at libav.org
        ReportedBy: sre at ring0.de


Hi,

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