Do you know if it works with any previous versions of mp4v2 from here, like 
r355 or 1.9.1?

I first tried with 1.9.1 and had that very issue(thats why I tried with the 
latest trunk)

Okay, good to know.  a few other things you could try to help me get this fixed:

1. Could you try r355?
2. Could you attach the mp4 file and png to this thread so I can test?
3. Does it work with any other image types, like bmp or jpeg, or are they all 
broken?

Thanks!

I had some time to look into this today, and it turns out it was likely broken 
since r73.  In r73, File::Read() was changed to return false in the event of 
success, but this code in mp4tags.cpp was never updated to reflect the change:

                        File in( tags[i], File::MODE_READ );
                        if( !in.open() ) {
                            MP4TagArtwork art;
                            art.size = (uint32_t)in.size;
                            art.data = malloc( art.size );
                            art.type = MP4_ART_UNDEFINED;

                            File::Size nin;
                            if( !in.read( art.data, art.size, nin ) && nin == art.size ) {
                                if( mdata->artworkCount )
                                    MP4TagsRemoveArtwork( mdata, 0 );
                                MP4TagsAddArtwork( mdata, &art );
                            }

                            free( art.data );
                            in.close();

...the in.read() call will return false in the event of success, which means 
the artwork is never added.  So it just needs a "!".  This will be fixed in 
r394 (sorry, having some issues with source control at the moment, it's not 
cooperating...)

fixed in r394 - could you retest with trunk and let me know if it's fixed on 
your end?  Thanks!
