Examples of use
Network Camera (RTSP Stream)
var inputSource = new StreamInputSource("rtsp://videoserver.example/testvideo.mp4");
var cancellationTokenSource = new CancellationTokenSource();
var client = new VideoStreamClient();
client.NewImageReceived += NewImageReceived;
var task = client.StartFrameReaderAsync(inputSource, OutputImageFormat.Bmp, cancellationTokenSource.Token);
//wait for exit
Console.ReadLine();
client.NewImageReceived -= NewImageReceived;
void NewImageReceived(byte[] imageData)
{
File.WriteAllBytes($@"{DateTime.Now.Ticks}.bmp", imageData);
}Webcam
You can find out the name of your webcam in the Windows Device Manager in the section Cameras
var inputSource = new WebcamInputSource("HP HD Camera");
var cancellationTokenSource = new CancellationTokenSource();
var client = new VideoStreamClient();
client.NewImageReceived += NewImageReceived;
var task = client.StartFrameReaderAsync(inputSource, OutputImageFormat.Bmp, cancellationTokenSource.Token);
//wait for exit
Console.ReadLine();
client.NewImageReceived -= NewImageReceived;
void NewImageReceived(byte[] imageData)
{
File.WriteAllBytes($@"{DateTime.Now.Ticks}.bmp", imageData);
}Custom Input Source - Select manual attributes
var inputSource = new CustomInputSource("-rtsp_transport tcp -i rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4 -vf transpose=dir=1");
var cancellationTokenSource = new CancellationTokenSource();
var client = new VideoStreamClient();
client.NewImageReceived += NewImageReceived;
var task = client.StartFrameReaderAsync(inputSource, OutputImageFormat.Bmp, cancellationTokenSource.Token);
//wait for exit
Console.ReadLine();
client.NewImageReceived -= NewImageReceived;
void NewImageReceived(byte[] imageData)
{
File.WriteAllBytes($@"{DateTime.Now.Ticks}.bmp", imageData);
