标签库：如何编辑专辑艺术家？ [英] taglib : how to edit Album Artist?

问题描述

如何修改MP3文件的专辑艺术家字段与库标签库？
是否有类似的东西：

How to modify the "Album Artist" field of a MP3 file with the library TagLib ? Is there something similar to :

f.tag()->setArtist("blabla");

推荐答案

ID3v2的实际上并不支持所谓的专辑艺术家字段中。的iTunes使用TPE2帧，这被认为是：

ID3v2 doesn't actually support a field called "album artist". iTunes uses the TPE2 frame, which is supposed to be:

  在'乐队/乐团/伴奏'帧用于有关在录制表演的更多信息。

TPE2
The 'Band/Orchestra/Accompaniment' frame is used for additional information about the performers in the recording.

有关帧的完整列表，请参阅 http://id3.org/id3v2.3.0#Declared_ID3v2_frames

For a complete list of frames see http://id3.org/id3v2.3.0#Declared_ID3v2_frames.

要编写与标签库，这会做的伎俩：

To write that with TagLib, this would do the trick:

#include <mpegfile.h>
#include <id3v2tag.h>
#include <textidentificationframe.h>

int main()
{
    TagLib::MPEG::File file("foo.mp3");
    TagLib::ByteVector handle = "TPE2";
    TagLib::String value = "bar";
    TagLib::ID3v2::Tag *tag = file.ID3v2Tag(true);

    if(!tag->frameList(handle).isEmpty())
    {
        tag->frameList(handle).front()->setText(value);
    }
    else
    {
        TagLib::ID3v2::TextIdentificationFrame *frame =
            new TagLib::ID3v2::TextIdentificationFrame(handle, TagLib::String::UTF8);
        tag->addFrame(frame);
        frame->setText(value);
    }

    file.save();

    return 0;
}

如果你只是想删除的图像，你可以简单地做：

If you just want to remove the frames, you can simply do:

TagLib::MPEG::File file("foo.mp3");
TagLib::ID3v2::Tag *tag = file.ID3v2Tag();

if(tag)
{
    tag->removeFrames("TPE2");
    file.save();
}
