Answer 1

FFMPEG project has a tool, called ffprobe which can provide you the information you need about your multimedia files and ouput the information in a nicely formated JSON.

Take a look at this answer for an example.

Answer 2

Using Windows Media Player Component also, we can get the duration of the video.
Following code snippet may help you guys :

using WMPLib;
// ...
var player = new WindowsMediaPlayer();
var clip = player.newMedia(filePath);
Console.WriteLine(TimeSpan.FromSeconds(clip.duration));

and don't forget to add the reference of wmp.dll which will be present in System32 folder.

Answer 3

I had the same problem and we built a wrapper for ffprobe Alturos.VideoInfo. You can use it simply by installing the nuget package. Also the ffprobe binary is required.

PM> install-package Alturos.VideoInfo

Example

var videoFilePath = "myVideo.mp4";

var videoAnalyer = new VideoAnalyzer("ffprobe.exe");
var analyzeResult = videoAnalyer.GetVideoInfo(videoFilePath);

var duration = analyzeResult.VideoInfo.Format.Duration;

Answer 4

IMHO you could use MediaInfo which gives you a lot of information about media files.
There is a CLI for it so you can use it from your code and get info you need.
You can take a look at this link.

Answer 5

StreamReader errorreader;
string InterviewID = txtToolsInterviewID.Text;

Process ffmpeg = new Process();

ffmpeg.StartInfo.UseShellExecute = false;
ffmpeg.StartInfo.ErrorDialog = false;
ffmpeg.StartInfo.RedirectStandardError = true;

ffmpeg.StartInfo.FileName = Server.MapPath("ffmpeg.exe");
ffmpeg.StartInfo.Arguments = "-i " + Server.MapPath("videos") + "\\226.flv";


ffmpeg.Start();

errorreader = ffmpeg.StandardError;

ffmpeg.WaitForExit();

string result = errorreader.ReadToEnd();

string duration = result.Substring(result.IndexOf("Duration: ") + ("Duration: ").Length, ("00:00:00.00").Length);

You can use DirectShow API MediaDet object, through DirectShow.NET wrapper library. See Getting length of video for code sample, get_StreamLength gets you the duration in seconds. This assumes Windows has MPEG-4 demultiplexer installed (requires third party components with Windows prior to 7, I believe the same applies to another answer by cezor, there are free to redistribute components though).
