How to get video duration from mp4, wmv, flv, mov videos

Question

Alright. Actually i need mostly the mp4 format. But if it is possible to get for other types as well that would be nice. I just need to read the duration of the file. How ca

Answer 1

You could also use windows media player, although it don't support alle file types you requested

using WMPLib;

public Double Duration(String file)
    {
        WindowsMediaPlayer wmp = new WindowsMediaPlayerClass();
        IWMPMedia mediainfo = wmp.newMedia(file);
        return mediainfo.duration;
    }
}

Answer 2

I found the NReco.VideoInfo library to be the best option and far simpler than some of those above. It's a simple as giving the library a file path and it spits out the metadata:

var ffProbe = new FFProbe();
var videoInfo = ffProbe.GetMediaInfo(blob.Uri.AbsoluteUri);
return videoInfo.Duration.TotalMilliseconds;

I think you are looking for FFMPEG - https://ffmpeg.org/

there are also some free alternatives that you can read about them in this question - Using FFmpeg in .net?

   FFMpeg.NET
   FFMpeg-Sharp
   FFLib.NET

you can see this link for examples of using FFMPEG and finding the duration - http://jasonjano.wordpress.com/2010/02/09/a-simple-c-wrapper-for-ffmpeg/

        public VideoFile GetVideoInfo(string inputPath)
        {
            VideoFile vf = null;
            try
            {
                vf = new VideoFile(inputPath);
            }
            catch (Exception ex)
            {
                throw ex;
            }
            GetVideoInfo(vf);
            return vf;
        }
        public void GetVideoInfo(VideoFile input)
        {
            //set up the parameters for video info
            string Params = string.Format("-i {0}", input.Path);
            string output = RunProcess(Params);
            input.RawInfo = output;

            //get duration
            Regex re = new Regex("[D|d]uration:.((\\d|:|\\.)*)");
            Match m = re.Match(input.RawInfo);

            if (m.Success)
            {
                string duration = m.Groups[1].Value;
                string[] timepieces = duration.Split(new char[] { ':', '.' });
                if (timepieces.Length == 4)
                {
                    input.Duration = new TimeSpan(0, Convert.ToInt16(timepieces[0]), Convert.ToInt16(timepieces[1]), Convert.ToInt16(timepieces[2]), Convert.ToInt16(timepieces[3]));
                }
            }
       }

Answer 4

This answer about P/Invoke for Shell32 reminded me of the Windows API Code Pack to access common Windows Vista/7/2008/2008R2 APIs.

It was very easy, using the PropertyEdit demo in the included samples, to figure out the Shell32 API to get various media file properties, like duration.

I assume the same prerequisite applies for having the proper demultiplexers installed, but it was quite simple, as it only required adding references to Microsoft.WindowsAPICodePack.dll and Microsoft.WindowsAPICodePack.Shell.dll and the following code:

using Microsoft.WindowsAPICodePack.Shell;
using Microsoft.WindowsAPICodePack.Shell.PropertySystem;

using (ShellObject shell = ShellObject.FromParsingName(filePath))
{
    // alternatively: shell.Properties.GetProperty("System.Media.Duration");
    IShellProperty prop = shell.Properties.System.Media.Duration; 
    // Duration will be formatted as 00:44:08
    string duration = prop.FormatForDisplay(PropertyDescriptionFormatOptions.None);
}

Other stuff

Some common properties for an MPEG-4/AAC audio media file:

System.Audio.Format = {00001610-0000-0010-8000-00AA00389B71}
System.Media.Duration = 00:44:08
System.Audio.EncodingBitrate = ?56kbps
System.Audio.SampleRate = ?32 kHz
System.Audio.SampleSize = ?16 bit
System.Audio.ChannelCount = 2 (stereo)
System.Audio.StreamNumber = 1
System.DRM.IsProtected = No
System.KindText = Music
System.Kind = Music

It's easy to iterate through all properties if you're looking for the available metadata:

using (ShellPropertyCollection properties = new ShellPropertyCollection(filePath))
{
    foreach (IShellProperty prop in properties)
    {
        string value = (prop.ValueAsObject == null) ? "" : prop.FormatForDisplay(PropertyDescriptionFormatOptions.None);
        Console.WriteLine("{0} = {1}", prop.CanonicalName, value);
    }
}
