IP cameras and network sources

Products: Video Capture SDK .Net

Engines: VideoCaptureCore, VideoCaptureCoreX

The SDK supports IP cameras as a source. You can use the following types of IP cameras:

• ONVIF cameras
• RTSP cameras
• HTTP MJPEG cameras
• UDP cameras and streams
• NDI cameras
• SRT servers and cameras
• VNC servers

Universal source for RTSP, RTMP, HTTP and other protocols

VideoCaptureCore

// Set source
VideoCapture1.IP_Camera_Source = new IPCameraSourceSettings
{
    URL = "url",
    Login = "login",
    Password = "password",
    AudioCapture = true, // true to capture audio, false to ignore audio
    Type = VFIPSource.Auto_VLC
};

The type of the source can be set to:

• Auto_VLC - use the VLC engine
• Auto_FFMPEG - use the FFMPEG engine
• Auto_LAV - use the LAV engine

Custom FFMPEG settings

Using the FFMPEG source, you can set custom parameters using the FFMPEG_CustomOptions property. The avformat_open_input call will use these parameters in the dictionary when opening a stream.

The sample below shows how to set the rtsp_transport and timeout parameters.

VideoCapture1.IP_Camera_Source.FFMPEG_CustomOptions.Add("rtsp_transport", "tcp");
VideoCapture1.IP_Camera_Source.FFMPEG_CustomOptions.Add("timeout", "3000000");

VideoCaptureCoreX

// Add login and password to the address if necessary
var uri = new Uri("some URL");
if (!string.IsNullOrEmpty(login) && !string.IsNullOrEmpty(password))
{
    uri = new UriBuilder(uri) { UserName = login, Password = password }.Uri;
}

// Create a universal source object. Set renderAudio to true to capture audio, false to ignore audio.
var source = await UniversalSourceSettings.CreateAsync(uri, renderAudio: audio, ignoreMediaInfoReader: true);

// Set the source to the VideoCaptureCoreX object
VideoCapture1.Video_Source = source;

Low-latency MJPEG source

SDK has a special mode for low latency MJPEG streaming. Typically, the latency is less than 100ms.

VideoCaptureCore

// Create settings object
var settings = new IPCameraSourceSettings

// Specify URL and credentials
// ...

// Set HTTP MJPEG Low Latency mode
settings.Type = IPSourceEngine.HTTP_MJPEG_LowLatency;

// Set settings to the VideoCaptureCore object
VideoCapture1.IP_Camera_Source = settings;

VideoCaptureCoreX

 // Create HTTP MJPEG source settings object
 var mjpeg = await HTTPMJPEGSourceSettings.CreateAsync(new Uri(cbIPURL.Text), edIPLogin.Text, edIPPassword.Text);

 // Apply settings to the VideoCaptureCoreX object
 VideoCapture1.Video_Source = mjpeg;

SRT source

You can play video from SRT server or camera using the SRT source.

VideoCaptureCoreX

// Create SRT source settings object
var srt = await SRTSourceSettings.CreateAsync("SRT server URL");

// Set the source to the VideoCaptureCoreX object
VideoCapture1.Video_Source = srt;

Network disconnect event

VideoCaptureCore

The SDK can detect network disconnects and reconnects. To enable this feature, set DisconnectEventInterval to 5 seconds or more.

Use the OnNetworkSourceDisconnect event to handle disconnects.

private void VideoCapture1_OnNetworkSourceDisconnect(object sender, EventArgs e)
    {
        Invoke((Action)(
            async () =>
                {
                    await VideoCapture1.StopAsync();

                    MessageBox.Show(this, "Network source stopped or disconnected!");
                }));
    }

VNC source

You can connect to VNC servers and capture video from them.

VideoCaptureCoreX

// Create VNC source settings object
var vncSettings = new VNCSourceSettings();

// Set the source URL or host and port
if (useHostAndPort)
{
    vncSettings.Host = "host";
    vncSettings.Port = port;
}
else
{
    vncSettings.Uri = "vnc://something";
}

// Set the password
vncSettings.Password = "password";

// Set the source to the VideoCaptureCoreX object
videoCapture.Video_Source = vncSettings;
