Does it happen for any file? If so, can you provide some sample file?
This library is used in https://github.com/nazar-pc/CleverStyle-Music and I never seen this happening.

Same here, got the same file in "picture" property, for all files tested.
But i'm not sure if i use it correctly, Can you provide some exemple ?

Thanks

Here is an example in CoffeeScript in mentioned project: https://github.com/nazar-pc/CleverStyle-Music/blob/master/html/cs-music-player/script.coffee#L229
Better show your example so that I can suggest something.

Thanks for your reply,

Here is how i use it, i work on a ionic project, and browse audio file across an android device, for each audio file, i fetch some data, the parser work very well and fast, but "picture" return the same File object.

`getFile: function (fileEntry) {

        var deferred = $q.defer();

        fileEntry.file(function(file) {

            if ( file.type !== null && file.type.indexOf('audio') < 0 ) return deferred.resolve(false);

            // Create media object
            var media = new Media(fileEntry.fullPath);

            // Get meta and stuff
            parse_audio_metadata(file, function (tag) {

                console.log(tag);

                var result = {
                    coverUrl: tag.picture ? tag.picture.localURL : false,
                    description: '',
                    id: media.id,
                    provider: 'device',
                    score: '',
                    title: tag.title,
                    artist: tag.artist,
                    album: tag.album,
                    genre: tag.genre,
                    url: file.fullPath,
                    media: media,
                };

                deferred.resolve(result);

            }, function parseError(error) {
                console.log(error);
                deferred.resolve(false);
            })

        })

        return deferred.promise;

    },

Did you try to show that image on screen?
Because it is actually taken from that file, I think this might be a reason why you got such result. Also compare size of picture with size of source file whether they differ anyhow.
It should be fine, since other tags were extracted properly.

[Fabiencdp]

Thanks again, the size of File and Picture are the same, start and end looks good.
But how can you display an image with that kind of blob ?

[nazar-pc]

url = URL.createObjectURL(metadata.picture) and you'll get something you can use as URL to add it on the page. Also if you work with multiple such objects do not forget to call URL.revokeObjectURL(url) afterwards to avoid memory leaks.

[Fabiencdp]

It fail too with message :

Failed to execute 'createObjectURL' on 'URL': No function was found that matched the signature provided.

I think something dont work with the Cordova File Plugin, i'll try to find a solution.
