> The fix proposed and executed in this ticket works for a specific
workflow. However there are other workflows that require all audio tracks
to be enabled upon the MOV being created such as delivery to iTunes, or
Netflix, or professional post production facilities internal workflows. I
would like to propose (if it's possible) to have some type of switch in
the code allowing someone to tell FFMPEG to either make only track 1
enabled or to make all tracks enabled.
I work with many people facing this same issue. It's surprising to me that
the FFmpeg developers would introduce a behavior like this without any
mechanism of control, to satisfy one user's request:
https://trac.ffmpeg.org/ticket/2626
That said, per the attached screen shot, the issue here is that the audio
tracks are being created as alternates to each other, so there is no way
to enable all created audio tracks, and save, unless you remove the
Alternate assignment in QuickTime Player 7 (Pro). This behavior makes a
major assumption that your audio content is alternative ie. languages that
need to be switched, instead of perhaps stereo, 5.1, and M&E across 3
audio tracks of the QuickTime file. Is there any plan to fix this?
