(Asked by: username_0 on 2020-07-27)

I have a set of media where I'm trying to strip an audio track and copy everything else over. My command is like so:
ffmpeg -i input.m4v -dn -map 0 -map -0:a:2 -c copy output.m4v

The source file has the following metadata:

Without the -dn flag I get an error when running the command:

Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input

When I use the -dn flag I can't select a chapter on my Apple TV which leads me to believe the metadata is incorrect.
When I try and run ffprobe on the produced file I get:
[m4v @ 0x7f966880b800] Format m4v detected only with low score of 1, misdetection possible!
[m4v @ 0x7f966880b800] Could not find codec parameters for stream 0 (Video: mpeg4, none): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options

I also tried adding -map_chapters and -map_metadata but I get an error:
[ipod @ 0x7f93a0026400] Tag text incompatible with output codec id '100359' ([0][0][0][0])
Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input

The command that resulted in the above is:
ffmpeg -i input.m4v -map 0 -map -0:a:2 -map_metadata 0 -map_chapters 0 -c copy output.m4v

What's the proper command to copy everything over EXCEPT the track I want to exclude?

A command like the following seemed to do the trick.
