TagLib

(aka Taglib-sharp) is a .NET platform-independent library (tested on Windows/Linux) for reading and writing metadata in media files, including video, audio, and photo formats. This is a convenient one-stop-shop to present or tag all your media collection, regardless of which format/container these might use. You can read/write the standard or more common tags/properties of a media, or you can also create and retrieve your own custom tags.

It supports the following formats (by file-extensions):

Video: mkv, ogv, avi, wmv, asf, mp4 (m4p, m4v), mpeg (mpg, mpe, mpv, mpg, m2v)
Audio: aa, aax, aac, aiff, ape, dsf, flac, m4a, m4b, m4p, mp3, mpc, mpp, ogg, oga, wav, wma, wv, webm
Images: bmp, gif, jpeg, pbm, pgm, ppm, pnm, pcx, png, tiff, dng, svg

It is API stable, with only API additions (not changes or removals) occuring in the 2.0 series.

Examples

Read/write metadata from a video

var tfile = TagLib.File.Create(@"C:\My video.avi");
string title = tfile.Tag.Title;
TimeSpan duration = tfile.Properties.Duration;
Console.WriteLine("Title: {0}, duration: {1}", title, duration);

// change title in the file
tfile.Tag.Title = "my new title";
tfile.Save();

Read/write metadata from a Audio file

var tfile = TagLib.File.Create(@"C:\My audio.mp3");
string title = tfile.Tag.Title;
TimeSpan duration = tfile.Properties.Duration;
Console.WriteLine("Title: {0}, duration: {1}", title, duration);

// change title in the file
tfile.Tag.Title = "my new title";
tfile.Save();

Read/write metadata from an Image

var tfile = TagLib.File.Create(@"C:\My picture.jpg");
string title = tfile.Tag.Title;
var tag =  tfile.Tag as TagLib.Image.CombinedImageTag;
DateTime? snapshot = tag.DateTime;
Console.WriteLine("Title: {0}, snapshot taken on {1}", title, snapshot);

// change title in the file
tfile.Tag.Title = "my new title";
tfile.Save();

Read/write custom tags from a specific format

var tfile = TagLib.File.Create(@"C:\My song.flac");
var custom = (TagLib.Ogg.XiphComment) tfile.GetTag(TagLib.TagTypes.Xiph);

// Read
string [] myfields = custom.GetField("MY_TAG");
Console.WriteLine("First MY_TAG entry: {0}", myfields[0]);

// Write
custom.SetField("MY_TAG", new string[] { "value1", "value2" });
custom.RemoveField("OTHER_FIELD");
rgFile.Save();
