possibility to create "disabled" tracks in MP4/MOV container missing

[julian]

hello
i need to create an MP4 file with an "disabled" audio track for playback on the AppleTV. it seems MP4 and MOV containers have the option to toggle whether tracks are enabled or disabled.

i've searched the manpage and googled to no avail, it seems ffmpeg is currently missing this capability. only thing i found is someone else looking for this too ( ​http://stackoverflow.com/questions/14409194/how-to-disable-non-1st-audio-streams-tracks-in-ffmpeg-for-mp4-files ).

please add the option to specify which tracks ( -map ) should be enabled or disabled when creating MP4 files.

currently i have to post process the files created by ffmpeg using MP4Box ( ​http://blog.jdknight.me/2011/05/handbrake-playstation-3-and-51-surround.html ).

thanks in advance for considering to implement this (or pointing me to the documentation if it really is already possible).

Rereading your ticket, I am not sure if I understand it:
Afaict, FFmpeg by default makes the first audio track "enabled" and the remaining audio tracks "disabled" which may not match your ticket description.

Please add your command line together with the complete, uncut console output to make this a valid ticket and to allow to reproduce the issue.

[julian]

i'm not seeing the second audio track being "disabled", i have to post process the files in MP4Box

[Carl Eugen Hoyos]

Please provide your failing ffmpeg command line (the one that produces the output file that you have to post process) together with the complete, uncut console output to make this a valid ticket and to allow developers to reproduce the problem.

[julian]

you are right, 1.2.1 disables a second audio track by default, but v1.0 (which i did use previously) does not - there must have been a recent change here.

i'm not sure in which version the change occurred, and it doesn't seem to be documented here: https://ffmpeg.org/ffmpeg.html

is there any way to control this behavior to specify which audio tracks should be en/disabled? if not, i'd like to see this added ;)

[Carl Eugen Hoyos]

Please always test current git head before opening tickets, see ​http://ffmpeg.org/bugreports.html

If you are interested in this issue, please provide a failing command line including the complete, uncut console output and explain the incorrect behaviour.

[julian]

please read my comment again, there is no failing command line (anymore). i'm happy that recent ffmpeg already disables the second audio track.

however there are still two issues here (and still no failing command line):

• the current behavior is not documented at all, and the change wasn't even documented in the changelog
• there is no way to control the behavior. what about users that DON'T want the second audio track to be disabled?

Thank you for testing!

This was a user-reported bug, bug fixes generally do not make it into the Changelog

• there is no way to control the behavior. what about users that DON'T want the second audio track to be disabled?

Please feel free to contribute to ​http://thread.gmane.org/gmane.comp.video.ffmpeg.user/46316
I don't think my main question was answered yet.

[julian]

2.1 creates the second audio track as enabled again (and again without option to 'disable' it) so i'd like to have this bug-report re-opened

[julian]

​https://dl.dropboxusercontent.com/u/7221986/bla.aac
​https://dl.dropboxusercontent.com/u/7221986/bla.mkv

ffmpeg -i bla.mkv -i bla.aac -map 0:0 -map 1:0 -map 0:1 -acodec copy -vcodec copy bla.mp4

with 1.2.4 this produces a MP4 with the second (surround) audio track being disabled, with 2.1 its enabled

[julian]

would a git bisect speed up a fix of this?

[Carl Eugen Hoyos]

Sorry for forgetting about this issue.
A bisect will hopefully not be necessary but a failing command line (a command line that does not work as expected) together with complete, uncut console output is needed: I am unable to produce an output mov file where the second audio track is enabled.

provided in comment 10 but i'll write it up again

1. download ​

2. ffmpeg-1.2.1 -i bla.mkv -i bla.aac -map 0:0 -map 1:0 -map 0:1 -acodec copy -vcodec copy bla-old.mp4
3. ffmpeg-2.2.1 -i bla.mkv -i bla.aac -map 0:0 -map 1:0 -map 0:1 -acodec copy -vcodec copy bla-new.mp4
4. open bla-old.mp4, the second audio track is disabled as it should be. open bla-new.mp4, the second audio track is enabled

I hope you understand why the console output was needed...

I opened ticket #3622, thank you for the reminder!

[julian]

ok full output from now on ;) thanks for taking care of the issue

[julian]

i had to change the location of the uploaded file to reproduce the issue:
