Cover will removed by write data

[kanbekotori]

My mp3 has a cover and i run the code, the cover has removed.
ffmetadata.write(p, data, function(err) {
if (err) {
console.log(err);
} else {
ffmetadata.read(p, function(err, data) {
if (err) console.error("Error reading metadata", err);
else console.log(data);
});
}
});

I have the same problem - I am using ffmetadata to rewrite data to files which have cover images, but after writing, the cover no longer seems to be there.

Same with me.

The current ffmpeg option only copies the first stream from the input file:

node-ffmetadata/index.js

Line 143 in c6cb960

maps = ['-map', '0:0'], // set as the first

This will be just the audio stream and not any other data encoded in subsequent streams (e.g., cover art). To copy all streams from the input, the map option needs to be changed to -map 0 instead of -map 0:0. Can anyone try this and let me know if it works for them?

This would have to be an option, as in my own workflow I like to strip all extra data out of audio file and re-attach my own cover art.

Partial success! It worked for the mp3 file I chose, but not an m4a file. Here's the error that I received when trying the m4a:

And here's the code I have that invokes ffmetadata:

var data = {

}
ffmetadata.write(filepath, data, function(err) {
    if (err) console.error("Error writing metadata", err);
    else console.log("Data written");
})

Finally, just to be certain that I modified the right code in the package, I now have inside getWriteArgs() the line maps = ['-map', '0'] rather than maps = ['-map', '0:0']

[parshap]

Yep your change sounds right. Does that m4a file work without the change? I'm not sure what's going on and the ffmpeg output is not very helpful. Can you share your test file? If you want to keep it private my email is parshap@gmail.com.

[parshap]

From this thread it sounds like ffmpeg may not support cover art for m4a files. https://trac.ffmpeg.org/ticket/2798

3 years ago by jamal

mov/mp4/m4a muxer currently doesn't support cover art.
A patch that implements this was submitted to ffmpeg-devel a few weeks ago.

It's 3 years old though so I'm not sure if the status has changed since then.

[Shudrum]

The issue for the covers on m4a seems to be fixed.

[RenautMestdagh]

The problem is, the tag "comment: Cover (front)" isn't (correctly) set. Don't know how to fix it tho. When I put in a metadata extractor, the value of the field "comment" is "Other".
