Select video and audio capture devices in Video Capture SDK .Net
You can download sample project from
GitHub.
Select video source
1. Get list of available video capture devices, fill combobox
foreach (var device in VideoCapture1.Video_CaptureDevicesInfo)
{
cbVideoInputDevice.Items.Add(device.Name);
}
VideoCapture1.Video_CaptureDevice = cbVideoInputDevice.Text;
3. Get list of available video formats and frame rates, fill combobox
var deviceItem = VideoCapture1.Video_CaptureDevicesInfo.First(device => device.Name == cbVideoInputDevice.Text);
if (deviceItem == null)
{
return;
}
cbVideoInputFormat.Items.Clear();
foreach (string format in deviceItem.VideoFormats)
{
cbVideoInputFormat.Items.Add(format);
}
cbFramerate.Items.Clear();
foreach (string frameRate in deviceItem.VideoFrameRates)
{
cbVideoFrameRate.Items.Add(frameRate);
}
VideoCapture1.Video_CaptureDevice_Format = cbVideoInputFormat.Text;
or automatically choose best video format.
VideoCapture1.Video_CaptureDevice_Format_UseBest = true;
VideoCapture1.Video_CaptureDevice_FrameRate = Convert.ToDouble(cbVideoFrameRate.Text);
6. Select needed video input (configure crossbar) if needed
Select audio source
1. Use video capture device as audio source, enumerate formats, fill combobox
VideoCapture1.Video_CaptureDevice_IsAudioSource = true;
cbAudioInputFormat.Items.Clear();
cbAudioInputLine.Items.Clear();
var deviceItem = VideoCapture1.Video_CaptureDevicesInfo.First(device => device.Name == cbVideoInputDevice.Text);
if (deviceItem != null)
{
foreach (string format in deviceItem.AudioFormats)
{
cbAudioInputFormat.Items.Add(format);
}
}
VideoCapture1.Audio_CaptureDevice_Format = cbAudioInputFormat.Text;
or automatically choose best audio format
VideoCapture1.Audio_CaptureDevice_Format_UseBest = true;
VideoCapture1.Audio_CaptureDevice_Line = cbAudioInputLine.Text;
