RE: mp4 (or m4a) editor

[Marcin Gondek <drixter%e-utp.net@localhost>]

Hi

AI is saying:

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

Or to show image before playing music:

ffmpeg -i input.m4a -i cover.jpg -map 0 -map 1 -c copy -disposition:v attached_pic -movflags +faststart output.m4a

Didn't tried.

Thanks,

Subject: mp4 (or m4a) editor

I've got about 1000 .mp4/.m4a files with no video, only audio.  Most of these files have embedded "album art" (presumably in .jpg format?).

But there are a few files that don't seem to have the .jpg

I can get .jpg from various sources, but (I think) I need some sort of editor to insert the .jpg into the .m4a files.

Any recommendations?
