Description
Previous versions of ffmpeg (such as 1.2.4 - confirmed) disabled extra audio tracks in MP4 containers to avoid having multiple 'default' tracks in the container. Using the current version of ffmpeg (git-0062869 (2013-11-12) from zoranoes builds) fails to do so, thus resulting in multiple default tracks in the container.
In my case, it prevents the resulting MP4 being played on an Apple TV 3, which has no audio if multiple 'default' tracks are present in the container. Note that this issue has been mentioned in older versions of ffmpeg as well (see https://trac.ffmpeg.org/ticket/2626), but was fixed in the 1.2.x line of ffmpeg at least.
