I'm trying to read the image size of a WMV file in C#.
I've tried using what is described here:
How do I get the duration of a video file using C#?
but the only attribute that has a value is Duration.
Any ideas ?
Thanks.
Only way I've seen it done is by playing it and attaching to the open event:
static WindowsMediaPlayerClass player;
static void Main()
{
player = new WindowsMediaPlayerClass();
IWMPMedia mediaInfo = player.newMedia("test.wmv");
player.OpenStateChange += new _WMPOCXEvents_OpenStateChangeEventHandler(player_OpenStateChange);
player.currentMedia = mediaInfo;
//...
Console.WriteLine("Done.");
Console.ReadKey();
}
private static void player_OpenStateChange(int state)
{
if (state == (int)WMPOpenState.wmposMediaOpen)
{
Console.WriteLine( "height = " + player.currentMedia.imageSourceHeight);
Console.WriteLine( "width = " + player.currentMedia.imageSourceWidth);
}
}
You'll want to dispose of any resources before exiting.
You use the code from the linked example, but you explicitly do a function call to get the height and width.
Example:
using WMPLib; // this file is called Interop.WMPLib.dll
WindowsMediaPlayerClass wmp = new WindowsMediaPlayerClass();
IWMPMedia mediaInfo = wmp.newMedia("myfile.wmv");
long height, width;
mediaInfo.get_imageSourceHeight(height);
mediaInfo.get_imageSourceWidth(width);
I prefer to use the free NReco.VideoInfo.dll. Mainly because I hate Windows Media Player. I have found that WMP is unreliable.
Here is the download link: http://www.nrecosite.com/video_info_net.aspx It's useful for other stuff too.
var ffProbe = new NReco.VideoInfo.FFProbe();
var videoInfo = ffProbe.GetMediaInfo(pathToFile);
Int32 tmpHeight = videoInfo.Streams[0].Height;
Int32 tmpWidth = videoInfo.Streams[0].Width;

Is there a way to play two sounds at the same time?
I know that SoundPlayer isn't able to do this.
I can't use SoundEffect as I believe it's only part of XNA.
The two required sounds will be called at unknown and random times. The sound needs to be be controlled after it is played. i.e., the sound must be able to be stopped before it has finished playing.
Reference PresentationCore and WindowsBase and try this...
var p1 = new System.Windows.Media.MediaPlayer();
p1.Open(new System.Uri(#"C:\windows\media\tada.wav"));
p1.Play();
// this sleep is here just so you can distinguish the two sounds playing simultaneously
System.Threading.Thread.Sleep(500);
var p2 = new System.Windows.Media.MediaPlayer();
p2.Open(new System.Uri(#"C:\windows\media\tada.wav"));
p2.Play();
EDIT
I received a downvote probably because at first glance this looks like it will play the second sound after the first is finished. It doesn't, they are played by windows asynchronously. The sleep is there so if you test this code verbatim you can hear the sounds play together, it wouldn't be noticeable without the delay since they are the same sound.
This code demonstrates the two sounds playing on separate threads on top of each other, which is sort of pointless since the playback doesn't block anyway
new System.Threading.Thread(() => {
var c = new System.Windows.Media.MediaPlayer();
c.Open(new System.Uri(#"C:\windows\media\tada.wav"));
c.Play();
}).Start();
System.Threading.Thread.Sleep(500);
new System.Threading.Thread(() => {
var c = new System.Windows.Media.MediaPlayer();
c.Open(new System.Uri(#"C:\windows\media\tada.wav"));
c.Play();
}).Start();
http://msdn.microsoft.com/en-us/library/system.windows.media.mediaplayer.stop.aspx
The class also has the control you need to stop playback
The "MediaPlayer" object will not let you play two sounds at once, even if you create two instances. You will need to bring in the native windows API "mciSendString".
[DllImport("winmm.dll")]
static extern Int32 mciSendString(string command, StringBuilder buffer, int bufferSize, IntPtr hwndCallback);
public Form1()
{
InitializeComponent();
mciSendString(#"open C:\Users\Jono\Desktop\applause.wav type waveaudio alias applause", null, 0, IntPtr.Zero);
mciSendString(#"play applause", null, 0, IntPtr.Zero);
mciSendString(#"open C:\Users\Jono\Desktop\foghorn.wav type waveaudio alias foghorn", null, 0, IntPtr.Zero);
mciSendString(#"play foghorn", null, 0, IntPtr.Zero);
}
check PlaySound method here http://msdn.microsoft.com/en-us/library/aa909766.aspx, and its flag SND_ASYNC .
Solution :
Hi,
I was developing a WP8 App and i needed multiple sounds to play simultaneously, the solutions mentioned above didnt work for me, So i used the XNA framwork. here is the link
http://msdn.microsoft.com/en-us/library/ff842408.aspx
and then play ur sound files like this...
SoundEffect Sound = SoundEffect.FromStream(Application.GetResourceStream(new Uri("Assets/Sounds/wav/sound.wav", UriKind.Relative)).Stream);
Sound.Play();
For looping...
SoundEffectInstance Sound = SoundEffect.FromStream(Application.GetResourceStream(new Uri("Assets/Sounds/wav/sound.wav", UriKind.Relative)).Stream).CreateInstance();
Sound.IsLooped = true;
Sound.Play();
Note: the files must be in ".wav" (PCM, 8 or 16-bit, 8KHz to 48KHz, mono or stereo) format
From http://alvas.net/alvas.audio,samples.aspx#sample7 and http://alvas.net/alvas.audio,samples.aspx#sample6
Player pl = new Player();
byte[] arr = File.ReadAllBytes(#"in.wav");
pl.Play(arr);
Player pl2 = new Player();
pl2.FileName = "123.mp3";
pl2.Play();
or mix audio data before playing How to mix to mix two audio file..
private void Mix(string outfile, string infile1, string infile2, int shiftSec)
{
WaveReader wr1 = new WaveReader(File.OpenRead(infile1));
WaveReader wr2 = new WaveReader(File.OpenRead(infile2));
IntPtr format1 = wr1.ReadFormat();
WaveFormat wf = AudioCompressionManager.GetWaveFormat(format1);
WaveWriter ww = new WaveWriter(File.Create(outfile), AudioCompressionManager.FormatBytes(format1));
byte[] data0 = wr1.ReadData(0, shiftSec);
byte[] data1 = wr1.ReadData(shiftSec);
byte[] data2 = wr2.ReadData();
byte[] mixData = AudioCompressionManager.Mix(format1, data2, data1);
ww.WriteData(data0);
ww.WriteData(mixData);
ww.Close();
wr2.Close();
wr1.Close();
}
The accepted answer didn't work for me.
Here is what worked:
Make sure you add references to PresentationCore and WindowsBase dlls.
private void Form1_Load(object sender, EventArgs e)
{
System.Media.SoundPlayer player = new System.Media.SoundPlayer(#"C:\Users\me\source\repos\TacticalIslandSurvival\sounds\blazer rail.wav");
player.PlayLooping();
}
private void button1_MouseEnter(object sender, EventArgs e)
{
var p1 = new System.Windows.Media.MediaPlayer();
p1.Open(new System.Uri(#"C:\Users\me\source\repos\TacticalIslandSurvival\sounds\click.wav"));
p1.Play();
}
I need a way to take screenshots of my functional tests. Right now I'm using Selenium 2 with C# bindings. I pretty much want to take a screenshot at the end of the test to make sure the desired page is displayed. Are there any particular tools you guys know of that I can incorporate into my C# code that will trigger a screenshot? I couldn't find a built-in Selenium 2 solution (without looking it over).
To do screenshots in Selenium 2 you need to do the following
driver = new FireFoxDriver(); // Should work in other Browser Drivers
driver.Navigate().GoToUrl("http://www.theautomatedtester.co.uk");
Screenshot ss = ((ITakesScreenshot) driver).GetScreenshot();
//Use it as you want now
string screenshot = ss.AsBase64EncodedString;
byte[] screenshotAsByteArray = ss.AsByteArray;
ss.SaveAsFile("filename", ImageFormat.Png); //use any of the built in image formating
ss.ToString();//same as string screenshot = ss.AsBase64EncodedString;
That code should work, as I quickly tested it in IronPython Repl. See the IronPython code below
import clr
clr.AddReference("WebDriver.Common.dll")
clr.AddReference("WebDriver.Firefox.dll")
from OpenQA.Selenium import *
from OpenQA.Selenium.Firefox import *
driver = FirefoxDriver()
driver.Navigate().GoToUrl("http://www.theautomatedtester.co.uk")
s = driver.GetScreenshot()
s.AsBaseEncodedString
# HUGE string appears in the REPL
var driver = new InternetExplorerDriver();
driver.Navigate().GoToUrl("http://www.google.com");
var ss = driver.GetScreenshot();
ss.SaveAsFile("ss.png", System.Drawing.Imaging.ImageFormat.Png);
I don't know if it matters, but I ended up having to cast the driver when i was writing in c#.
something like:
Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();
Just use the extension method TakeScreenshot() in one line of code.
IWebDriver driver = new InternetExplorerDriver();
driver.Navigate().GoToUrl("Your_Homepage_Url");
driver.TakeScreenshot().SaveAsFile("file_name_string", ImageFormat.Jpeg);
Add a reference of System.Drawing in your solution/project.
Use System.Drawing.Imaging namespace in your test.

This code will help you to take screen shot
JAVA
protected void fullPageScreenshot(String testname) {
String timeStamp = new SimpleDateFormat("dd_MM_yyyy_HH_mm_ss").format(Calendar.getInstance().getTime());
String imageName = testname + "-" + timeStamp + ".png";
Screenshot screenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(2000))

try {
ImageIO.write(screenshot.getImage(), "PNG", new File("./FullPage_Screenshots/" + imageName));
} catch (Exception e) {
System.out.println("Capturing FullPage Screenshot failed");
}
}
use Ashot library to take fullpage screenshots - even where pages needs to be scrolled
https://mvnrepository.com/artifact/ru.yandex.qatools.ashot/ashot/1.5.4
Use System.Drawing.Imaging reference.
Following code can be used for taking screenshot.
IWebDriver driver = new FirefoxDriver();
ITakesScreenshot screenshotDriver = driver as ITakesScreenshot;
Screenshot screenshot = screenshotDriver.GetScreenshot();
String fp = "D:\\" + "snapshot" + "_"+ DateTime.Now.ToString("dd_MMMM_hh_mm_ss_tt") + ".png";
screenshot.SaveAsFile(fp, ImageFormat.Png);
Notes:
Timestamp has two advantages:
1) You'll get to know the perfect DateTime when screenshot is taken.
2) SaveAsFile function overwrites the existing file. So, DateTime can help for different file creation.
ScreenCaptureJob scj;
scj = new ScreenCaptureJob();
// Specify the path & file name in which you want to save
scj.OutputScreenCaptureFileName = #"C:\Users\jpavankumar\Desktop\Screencaptuere\ScreenRecording4.wmv";
// Start the Screen Capture Job
scj.Start(); scj.Stop();
Try this code out here ... hope it will be useful to you .... !
Define this in global code :
var counter = DateTime.Now.Ticks.ToString();
((ITakesScreenshot)driver).GetScreenshot().SaveAsFile((snap +counter + ".jpg").ToString(), OpenQA.Selenium.ScreenshotImageFormat.Jpeg);
test.Log(LogStatus.Fail, "Snapshot below: " + test.AddScreenCapture(snap + counter + ".jpg"));
driver.Url = "https://www.amazon.in/";
//Store image in bin folder
((ITakesScreenshot)driver).GetScreenshot().SaveAsFile("CurrentPage.png");
//Store image in D drive
((ITakesScreenshot)driver).GetScreenshot().SaveAsFile(#"D:\CurrentPage.png");
Best way to take screenshot and store in the file location in a generic way in python :
def screenShots(self):
fileName= NewFile + "." + str(round(time.time() * 1000)) + ".png"
screenshotDirectory = "../screenshot/" #Move to that directory where you want ot store the screenshot
relativeFileName = screenshotDirectory + fileName
currentDirectory = os.path.dirname(__file__)
destinationFile = os.path.join(currentDirectory,relativeFileName)
destinationDirectory = os.path.join(currentDirectory,screenshotDirectory)
try:
if not os.path.exists(destinationDirectory):
os.makedirs(destinationDirectory)
self.driver.save_screenshot(destinationFile)
self.log.info("Screenshot saved to directory" + destinationFile)
except:
self.log.error("Exception Occured")
print_stack()
Using selenium there were two calls I was familiar with: captureEntirePageScreenshot and captureScreenshot. You might want to look into those calls to see if they'll accomplish what you're after.
I am using NAudio for a screen recording software I am designing and I need to know if it's possible to not only control the specific application's volume but also display a VU Meter for the application's sound.
I've Googled all over the place and it seems I can only get a VU Meter for the devices currently on my computer and set the volume for those devices.
Even though I am using NAudio, I am open to other solutions.
I asked the question in more detail after this question. I have since found the answer so I will leave the answer here for those who stumble upon it. Trying to use NAudio & CSCore has gotten me quite familiar with so please ask if you need further assistance.
This block of code uses CSCore and is a modified and commented version of the answer found here:Getting individual windows application current volume output level as visualized in audio Mixer
class PeakClass
{
static int CurrentProcessID = 0000;
private static void Main(string[] args)
{
//Basically gets your default audio device and session attached to it
using (var sessionManager = GetDefaultAudioSessionManager2(DataFlow.Render))
{
using (var sessionEnumerator = sessionManager.GetSessionEnumerator())
{
//This will go through a list of all processes uses the device
//the code got two line above.
foreach (var session in sessionEnumerator)
{
//This block of code will get the peak value(value needed for VU Meter)
//For whatever process you need it for (I believe you can also check by name
//but I found that less reliable)
using (var session2 = session.QueryInterface<AudioSessionControl2>())
{
if(session2.ProcessID == CurrentProcessID)
{
using (var audioMeterInformation = session.QueryInterface<AudioMeterInformation>())
{
Console.WriteLine(audioMeterInformation.GetPeakValue());
}
}
}
//Uncomment this block of code if you need the peak values
//of all the processes
//
//using (var audioMeterInformation = session.QueryInterface<AudioMeterInformation>())
//{
// Console.WriteLine(audioMeterInformation.GetPeakValue());
//}
}
}
}
}
private static AudioSessionManager2 GetDefaultAudioSessionManager2(DataFlow dataFlow)
{
using (var enumerator = new MMDeviceEnumerator())
{
using (var device = enumerator.GetDefaultAudioEndpoint(dataFlow, Role.Multimedia))
{
Console.WriteLine("DefaultDevice: " + device.FriendlyName);
var sessionManager = AudioSessionManager2.FromMMDevice(device);
return sessionManager;
}
}
}
}
The following code block will allow you to change the volume of the device using NAudio
MMDevice VUDevice;
public void SetVolume(float vol)
{
if(vol > 0)
{
VUDevice.AudioEndpointVolume.Mute = false;
VUDevice.AudioEndpointVolume.MasterVolumeLevelScalar = vol;
}
else
{
VUDevice.AudioEndpointVolume.Mute = true;
}
Console.WriteLine(vol);
}
I have code from two different libraries only to answer the question I posted directly which was how to both set the volume and get VU Meter values (peak values). CSCore and NAudio are very similar so most of the code here is interchangeable.
I am developing a voice recorder app for Windows Phone 8.1 that stores the recordings on the local storage and a cloud storage service.
Everything's almost done except the fact that being able to pause an ongoing recording is a strong requirement for this app and I have to get it done.
Now, since PauseRecordAsync() and ResumeRecordAsync() are not available for Windows Phone 8.1 in the MediaCapture class but they will be available in Windows 10, I had to make a workaround: Every time the pause button is pressed, an audio chunk is saved in the temp folder and that file is stored in an array. When the stop button is pressed, the last chunk is stored in the array and the following Concatenation function is called and a final audio temp file is created:
public async Task<IStorageFile> ConcatenateAudio([ReadOnlyArray]IStorageFile[] audioFiles, IStorageFolder outputFolder, string outputfileName)
{
IStorageFile _OutputFile = await outputFolder.CreateFileAsync(outputfileName, CreationCollisionOption.ReplaceExisting);
MediaComposition _MediaComposition = new MediaComposition();
MediaEncodingProfile _MediaEncodingProfile = MediaEncodingProfile.CreateM4a(AudioEncodingQuality.High);
foreach (IStorageFile _AudioFile in audioFiles)
{
if(_AudioFile != null)
{
BackgroundAudioTrack _BackgroundAudioTrack = await BackgroundAudioTrack.CreateFromFileAsync(_AudioFile);
MediaClip _MediaClip = MediaClip.CreateFromColor(Windows.UI.Colors.Black, _BackgroundAudioTrack.TrimmedDuration); // A dummy black video is created witn the size of the current audio chunk.
// Without this, the duration of the MediaComposition object is always 0.
// It's a messy workaround but it gets the job done.
// Windows 10 will dirrectly support PauseRecordAsync() and ResumeRecordAsync() for MediaCapture tho'. Yay! :D
_MediaClip.Volume = 0;
_BackgroundAudioTrack.Volume = 1;
_MediaComposition.Clips.Add(_MediaClip);
_MediaComposition.BackgroundAudioTracks.Add(_BackgroundAudioTrack);
}
}
TranscodeFailureReason _TranscodeFailureReason = await _MediaComposition.RenderToFileAsync(_OutputFile, MediaTrimmingPreference.Fast, _MediaEncodingProfile);
if (_TranscodeFailureReason != TranscodeFailureReason.None)
{
throw new Exception("Audio Concatenation Failed: " + _TranscodeFailureReason.ToString());
}
return _OutputFile;
}
The problem is that when I play the file, all the audio chunks are played from the beginning of the final audio file at the same time instead of playing the second one right after the first one ended and so on. They are all playing one over the other. The length of the file on the other hand is correct and after all audio files finished playing, it's total silence.
I figured it out. I had to manually set the delay for BackgroundAudioTrack.
Here is the working code:
public async Task<IStorageFile> ConcatenateAudio([ReadOnlyArray]IStorageFile[] audioFiles, IStorageFolder outputFolder, string outputfileName)
{
IStorageFile _OutputFile = await outputFolder.CreateFileAsync(outputfileName, CreationCollisionOption.ReplaceExisting);
MediaComposition _MediaComposition = new MediaComposition();
MediaEncodingProfile _MediaEncodingProfile = MediaEncodingProfile.CreateM4a(AudioEncodingQuality.High);
TimeSpan totalDelay = TimeSpan.Zero;
foreach (IStorageFile _AudioFile in audioFiles)
{
if (_AudioFile != null)
{
BackgroundAudioTrack _BackgroundAudioTrack = await BackgroundAudioTrack.CreateFromFileAsync(_AudioFile);
MediaClip _MediaClip = MediaClip.CreateFromColor(Windows.UI.Colors.Black, _BackgroundAudioTrack.TrimmedDuration); // A dummy black video is created witn the size of the current audio chunk.
// Without this, the duration of the MediaComposition object is always 0.
// It's a messy workaround but it gets the job done.
// Windows 10 will dirrectly support PauseRecordAsync() and ResumeRecordAsync() for MediaCapture tho'. Yay! :D
_MediaClip.Volume = 0;
_BackgroundAudioTrack.Volume = 1;
_MediaComposition.Clips.Add(_MediaClip);
_MediaComposition.BackgroundAudioTracks.Add(_BackgroundAudioTrack);
_BackgroundAudioTrack.Delay = totalDelay;
totalDelay += _BackgroundAudioTrack.TrimmedDuration;
}
}
TranscodeFailureReason _TranscodeFailureReason = await _MediaComposition.RenderToFileAsync(_OutputFile, MediaTrimmingPreference.Fast, _MediaEncodingProfile);
if (_TranscodeFailureReason != TranscodeFailureReason.None)
{
throw new Exception("Audio Concatenation Failed: " + _TranscodeFailureReason.ToString());
}
return _OutputFile;
}
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 can i do that with C# 4.0 ?
So the thing i need is like this video is like : 13 minutes 12 seconds
I can use 3 third party exes too. Like they save the information about the file to a text file. I can parse that text file.
Thank you.
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);
}
}
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;
}
}
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).
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.
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]));
}
}
}
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.
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.
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 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;
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);
