FFmpeg, how to embed cover art (image) to .m4a

Question

Is there any way to embed cover art to m4a files?

This one works well for mp3 but doesn\'t work for m4a

ffmpeg         


        

Answer 1

It is possible with ffmpeg by specifying the attached_pic attribute on the image source via the -disposition parameter.

ffmpeg -i input.m4a -i image.jpg -map 0 -map 1 -c copy -disposition:v:1 attached_pic output.m4a 

Tested with ffmpeg 4.2.2.

A similar command is also given as an example in the ffmpeg docs, however be careful that the example is for adding covers to videos but not audio files. The -disposition parameter fails silently if the wrong stream is selected.
