Is it possible to stream in real-time a part of the screen for the local network? The ScreenCaptureJob can only stream to a file, and if a want to broadcast the file, it blocks because it's used by another process.
jobScreenCap = new ScreenCaptureJob();
// Creates a new job for encoding
job = new LiveJob();
var capRect = new System.Drawing.Rectangle(0, 0, 300, 200);
jobScreenCap.CaptureRectangle = capRect;
jobScreenCap.ScreenCaptureVideoProfile = new ScreenCaptureVideoProfile();
jobScreenCap.ScreenCaptureVideoProfile.Force16Pixels = true;
EncoderDevice device = jobScreenCap.VideoDeviceSource;
// -> the device is null
//var source = job.AddDeviceSource(device, null);
jobScreenCap.OutputPath = @"C:\output\ScreenCap";
var fileName = @"C:\output\ScreenCap\test1.ismv";
jobScreenCap.OutputScreenCaptureFileName = fileName;
jobScreenCap.Start();
LiveFileSource fileSource = job.AddFileSource(fileName);
// Makes this file the active source. Multiple files can be added
// and cued to move to each other at their ends
job.ActivateSource(fileSource);
var format = new PullBroadcastPublishFormat();
format.BroadcastPort = 8080;
job.PublishFormats.Add(format);
job.StartEncoding();
EDIT: New problem, it isnt running realtime.I'he got a delay of 10 seconds, I need real-time or at least 1second. It doesn't go through the Internet
Server code:
job = new LiveJob();
Collection<EncoderDevice> devices = EncoderDevices.FindDevices(EncoderDeviceType.Video);
EncoderDevice device = devices[0]; // maybe its somewhere else, so check for name ...
LiveDeviceSource source = job.AddDeviceSource(device, null);
source.ScreenCaptureSourceProperties = new ScreenCaptureSourceProperties
{
CaptureCursor = true,
CaptureLargeCursor = false,
FrameRate = 6,
CaptureLayeredWindow = true,
Height =600,
Width = 800,
Left = 0,
Top = 0,
};
job.ActivateSource(source);
// Finds and applys a smooth streaming preset
job.ApplyPreset(LivePresets.VC1256kDSL16x9);
// Sets up variable for fomat data
var format = new PullBroadcastPublishFormat {BroadcastPort = 8080};
job.PublishFormats.Add(format);
var data = job.BufferWindowSize;
job.StartEncoding();

Yes its possible since Encoder 4 SP1 (released this year)
Screen capture as a live source - Now you can select the screen as a device in Live projects to stream or archive.
(Source)
Programmatically:
The EncoderDevice
Collection returned by EncoderDevices.FindDevices(EncoderDeviceType.Video)
contains a device named "Screen Capture Source"
So something like this is what you would need:
LiveJob job = new LiveJob();
Collection<EncoderDevice> devices = EncoderDevices.FindDevices(EncoderDeviceType.Video);
EncoderDevice device = devices[0]; // maybe its somewhere else, so check for name ...
LiveDeviceSource source = job.AddDeviceSource(device, null);
source.ScreenCaptureSourceProperties = new ScreenCaptureSourceProperties(); // your Screen Capture settings here ...
