Taglib OGG CoverArt

shahriar25

Hi,
I want to get coverart of ogg files with taglib. I want to be able to get a QImage from the coverart. I searched the internet but I couldn't find a good solution. Can someone help?

Hi
disclaimer: I dont know taglib.

he seems to get image this way
image.loadFromData((const uchar *) coverArt.data().data(),coverArt.data().size());
So I wonder if it works for ogg too?

No it does not. I tried to treat the ogg file like m4a or mp3 bu it didn't work. I got these to functions for getting images:

QImage Music::imageForTag(TagLib::ID3v2::Tag *tag)
{
TagLib::ID3v2::FrameList l = tag->frameList("APIC");

QImage image;

if(l.isEmpty())
    return image;

TagLib::ID3v2::AttachedPictureFrame *f =
    static_cast<TagLib::ID3v2::AttachedPictureFrame *>(l.front());

image.loadFromData((const uchar *) f->picture().data(), f->picture().size());

return image;

}

QImage Music::imageForTagMP4(TagLib::MP4::Tag *tag)
{
QImage image;

if (tag->isEmpty())
    return image;

TagLib::MP4::ItemListMap itemsListMap = tag->itemListMap();
TagLib::MP4::Item coverItem = itemsListMap["covr"];
TagLib::MP4::CoverArtList coverArtList = coverItem.toCoverArtList();
TagLib::MP4::CoverArt coverArt = coverArtList.front();

image.loadFromData((const uchar *) coverArt.data().data(),coverArt.data().size());

return image;

}

Hi
I dont think ogg files have cover art. ( not as default)

It says it is officially not supported. then I will set the default coverart icon for them.
One more problem:
I have a QMenu in my QMenuBar and it has an icon and a title. when I run the project it shows the icon but when I click on it it shows the title but I want it to show the icon. what should I do?

Hi, if I create a default project and create a menu item and set its icon.
the icon and text is displayed all the time so not sure what happens to your icon/text.

What happens if you don't set text for the menu item?

@jsulm
when you don't click on it it shows the icon and when you do it becomes empty
