如何使用 taglib-sharp 在 iTunes 中设置“编译”标签？

Question

Is it possible to set the COMPILATION tag in iTunes using taglib-sharp?

Unfortunately, there seems to be nothing similar to this:

TagLib.File tagFile = TagLib.File.Create(file);  //.m4a file
tagFile.Tag.IsComilation = true;
tagFile.Save();

If not natively supported, is it possible to add an custom tag? Possibly through the use of TagLib.Mpeg4.AppleTag or TagLib.Mpeg4.AppleAdditionalInfoBox ?

There are a lot of questions answered here on how to do this using Id3v2 tags, however not for iTunes tags. I also could not find any helpful documentation.

Any help very much appreciated!

Answer 1

Based on the official specifications of ID3, you seem to be searching for the TCMP (iTunes Compilation Flag) Text Frame . Set it to the appropriate value and iTunes will do the rest obviously. The TCMP Text Frame takes a boolean value.

This is a simple text frame that iTunes uses to indicate if the file is part of a compilation.

  1 if part of a compilation 0 or not present if not part of a compilation 

So you can set it like this:

TagLib.File tagFile = TagLib.File.Create(file);
Id3v2.Tag tag = (Id3v2.Tag)tagFile.GetTag(TagTypes.Id3v2, true);
tag.SetTextFrame(FrameType.TCMP, "1"); // Change value accordingly...
tagFile.Save();

To make Farhan's answer work in TagLibSharp v2.3.0 I had to implement it something like this:

var mp3File = TagLib.File.Create(destTrackFile);                        
TagLib.Id3v2.Tag tag = (TagLib.Id3v2.Tag)mp3File.GetTag(TagLib.TagTypes.Id3v2, true);
TagLib.ReadOnlyByteVector TCMP = "TCMP";
tag.SetTextFrame(TCMP, "1");
mp3File.Save();
