Was this discussed as a patch and rejected? At least having it as a muxer or command line option seems to be a better solution than not having it at all in master as there are obviously use cases for it out there.

Hi Chris,

[FFmpeg-user] Enable all audio tracks for MOV container
Hi all -
I had been using a patch from this mailing list on the FFMPEG source code
to enable all audio tracks when encoding QuickTime MOV.
diff --git a/libavformat/movenc.c b/libavformat/movenc.c
index b6821d4..136adae 100644

However, it seems as though this no longer works as movenc has been
modified since it last worked for me with source code from March 25th 2016.
Is there a way to enable all audio tracks when encoding a MOV with the
current source or does anyone have an updated patch?
Thanks,
Chris
