Answer 1

I use MediaInfo with my C# apps, gives you a lot of information about media files.

Answer 2

These are the example class files for different languages found in the MediaInfo.dll zip

• MediaInfoDLL.cs
• MediaInfoDLL.def
• MediaInfoDLL.h
• MediaInfoDLL.java
• MediaInfoDLL.jsl
• MediaInfoDLL.pas
• MediaInfoDLL.py
• MediaInfoDLL.vb
• MediaInfoDLL_Static.h

You do have to use interop and I don't know if you can edit tags, I've never needed to do that but it's pretty much a swiss army knife at least for getting media information from files.

Answer 3

You can use free UltraID3Lib .NET library to read/write MP3 metadata.

Answer 4

I've been looking at the NTag project as well, which handles MP3/WMA/OGG. I don't know of a single library that handles audio and video files, so you might have to use a few.

Answer 5

I've recently used Tag Lib Sharp to write some C# apps for cleaning up and maintaining my music library. I found the library very easy to use and although i've only used it for MP3's, it appears to support a range of other music/video formats.

Answer 6

Looks like MediaInfo is read-only at this point, by the way: http://sourceforge.net/forum/message.php?msg_id=4241318&abmode=1

Very cool project, though. It's fun finding out about all this cool stuff here on SO.

Answer 7

I used COM interop to access DirectShow's Media Detector functionality.

This does work pretty well, but it's a right pain in the backside. You need to know lots about COM, win32 interop, and so on.

You can also use DirectShowNet which should handle most of that for you, I just didn't want to lug that whole thing around when I was only interested in the MediaDetector part

Answer 8

After struggling with NAudio (note that it can only run on Windows) and even TagLibSharp, I found out ATL .NET. What I love about it is it can work on Stream and it can detect formats as well.

1. Install z440.atl.core Nuget package:

dotnet add package z440.atl.core

2. Get the Track object and get as many information as you want:

var track = new Track(stream);

Console.WriteLine(track.Duration);
// More info
