See more:

C#

var player = new WindowsMediaPlayer();
var clip = player.newMedia(file.FullName);
lblLenght_.Text = (TimeSpan.FromSeconds(clip.duration)).ToString();       



ShellFile shellFile = ShellFile.FromFilePath(file.FullName);
lblFPS_.Text = (shellFile.Properties.System.Video.FrameRate.Value / 1000).ToString();

lblHeight_.Text = shellFile.Properties.System.Video.FrameHeight.Value.ToString() + " px";
lblWidth_.Text = shellFile.Properties.System.Video.FrameWidth.Value.ToString() + " px";
lblResolution_.Text = shellFile.Properties.System.Video.FrameWidth.Value.ToString() + "x" + shellFile.Properties.System.Video.FrameHeight.Value.ToString() + " px";
blBitrate_.Text = (shellFile.Properties.System.Video.TotalBitrate.Value / 1000).ToString() + " kb/s";

but the problem is that ShellFile supports only a few formats, so I found some FFMPEG or ffprobe uses but I don't know how to work with it. Can someone post the solution or some link to learn how to use it about my problem?

Do on simple step, look not at FFMPeg application, but at FFProbe. You can always download its source code and see what it does. Then, you can either start FFProbe as a separate process with appropriate command-line parameters, redirect its output stream StandardOutput (and StandardError) and pick it up with your applications.

Alternatively, use FFMpeg/Libavcodec library to do it in your process. Then you may need to use P/Invoke or C++/CLI. You can use some of available .NET wrappers.
