推荐答案

我从来没有这样做之前，对于视频文件，但我有一个MP3文件。您可以访问这样的框架：

I've never done this for video files before but I have for mp3 files. You can get access to those frames like this:

TagLib.File file = TagLib.File.Create(mp3FileName);
file.Tag.Title = "some title"; // you've got this
TagLib.Id3v2.Tag tag = (TagLib.Id3v2.Tag)file.GetTag(TagTypes.Id3v2);
tag.SetTextFrame("WOAR", "some url"); // WOAR = Official artist/performer webpage
file.Save();

您可以在维基百科查找的文本框的标识符列表：
的 ID3v2的框架规范（2.3版）

You can find a list of the text frame identifiers at Wikipedia: ID3v2 Frame Specification (Version 2.3)

我不知道，如果视频文件，给你同样的框架范围内的那ID3确实，虽然公告称维基百科也说（的非MP3和替代实施的）

I don't know if video files give you the same range of frames that ID3 does, though notice that Wikipedia also says (Implementation in non-mp3s and alternatives)

MP4还允许ID3的嵌入标签，这是广泛的支持。

MP4 also allows the embedding of an ID3 tag, and this is widely supported.

所以我猜想这也适用于MP4文件像你想。

So I would guess this also works for mp4 files like you're trying.
