            Bug ID: 752186
           Summary: gst-libav: avaudenc: fails at 2 channel wmav2 file
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: All
            Status: NEW
          Severity: blocker
          Priority: Normal
         Component: gst-libav
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: thiagossantos at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Fails because the file has 2 channels but no channel layout was provided.

>From a quick look between the differences in libav and ffmpeg it seems that
libav had a default channel layout function that would provide a LEFT|RIGHT
layout as default for stereo audio while ffmpeg just returns 0 (no layout
defined).

I can host the file somewhere if anyone is interested in taking a deeper look
at the issue.
