  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

  • Detection of virtual background on video using ffmpeg

    28 juillet 2021, par Marcos G

    I am trying with ffmpeg to detect the use of a virtual background on a video, like the ones used in Google Meet. I got some ideas, but none seem to work :

    


      

    • Egde color : When using a chroma key you can get shades of green/blue on the outline of the subject. This is called spill, and can be detectable, but gets discarded by the fact that you dont need a chroma key to fake a background (example : Google Meet).

      • 


    • Still image : Most of virtual backgrounds are a still image pasted behind the subject. The problem with detecting this is that most of the real backgrounds also are like still images, without much movement.

      • 


    • Blur : When faking a background without a chroma key the outline of the subject becomes very blurry (this is more noticeable when the subject moves), but I can't find a way to detect it using ffmpeg.

      • 


    


    How can I do this ? I'm open to trying other tecniques such as AI.

    


    Thanks in advance.

    


  • How to list all audio devices that are enabled and present for recording the output audio of the pc ?

    23 juin 2023, par Daniel Lip

    I want to record with ffmpeg later the entire desktop including audio.
I want to make that it will find for me automatic the recording audio device.

    


    I'm using MMDeviceEnumerator.

    


    all the other ways I tried returned empty list returned 0 audio devices. I tried with naudio and ffmpeg

    


    public Form1()
        {
            InitializeComponent();

            InitializeRecordingIndicator();

            MMDeviceEnumerator enumerator = new MMDeviceEnumerator();
            foreach (MMDevice device in enumerator.EnumerateAudioEndPoints(DataFlow.Capture, DeviceState.All))
            {
                StreamWriter w = new StreamWriter(@"d:\audiodev.txt", true);
                cmbAudioDevices.Items.Add(device.FriendlyName);
                w.WriteLine(device.FriendlyName + " " + device.State);
                w.Close();
            }
        }


    


    This is the list of all my audio deviceso n my system.
but they are all not present or disabled. and i have audio on my pc i can hear games videos anything.

    


    so what would i select from this list as audio device for recording the pc output audio ?
or maybe i need to find another way to find the right audio device ?

    this is how i tried with naudio but it didn't working it didn't find anything. :

    


    using NAudio.Wave;
...

// Enumerate and list audio input devices
var devices = WaveInEvent.DeviceCount;
for (int deviceId = 0; deviceId < devices; deviceId++)
{
    var deviceInfo = WaveInEvent.GetCapabilities(deviceId);
    Console.WriteLine($"Device ID: {deviceId}, Name: {deviceInfo.ProductName}");
}


    


    before that i tried with ffmpeg but also it didn't return anything :

    


    public static class FFmpegHelper
    {
        public static string[] GetAudioCaptureDevices()
        {
            string ffmpegPath = @"C:\path\to\ffmpeg.exe";
            Process process = new Process();
            process.StartInfo.FileName = ffmpegPath;
            process.StartInfo.Arguments = "-list_devices true -f dshow -i dummy";
            process.StartInfo.UseShellExecute = false;
            process.StartInfo.RedirectStandardError = true;
            process.StartInfo.CreateNoWindow = true;
            process.Start();
            process.WaitForExit();

            string output = process.StandardError.ReadToEnd();
            string[] lines = output.Split('\n');
            var devices = lines.Where(line => line.Contains("audio")).Select(line => line.Trim()).ToArray();
            return devices;
        }
    }


    


    using it :

    


    var audioDevices = FFmpegHelper.GetAudioCaptureDevices();
