Example
uEye.Streaming.Stream stream = new uEye.Streaming.Stream(); // initialized stream
uEye.Streaming.SessionInfo sessionInfo = new uEye.Streaming.SessionInfo(); // created session
uEye.Streaming.VideoConfiguration videoConfiguration = new uEye.Streaming.VideoConfiguration();
videoConfiguration.srcWidth = 1920;
videoConfiguration.srcHeight = 1080;
videoConfiguration.dstWidth = 1920;
videoConfiguration.dstHeight = 1080;
videoConfiguration.srcPixelformat = uEye.Streaming.Defines.PixelFormat.RGB24;
videoConfiguration.dstPixelformat = uEye.Streaming.Defines.PixelFormat.RGB24;
videoConfiguration.srcCodec = uEye.Streaming.Defines.Codec.None;
videoConfiguration.dstCodec = uEye.Streaming.Defines.Codec.MJPEG;
videoConfiguration.framerate = 30;
videoConfiguration.bitrate = 3000000; // = 3000 kbit/s
// create stream
uEye.Streaming.VideoStreamInfo streamInfo = new uEye.Streaming.VideoStreamInfo();
streamInfo.idSession = sessionInfo.idSession;
streamInfo.videoConfiguration = videoConfiguration;
uEye.Streaming.Defines.Status nRet = stream.AddStream(ref streamInfo);

// streamInfo.idStream is now set
