No Sound recorded
Awesome but I tried everything to try to record sound video works great no sound? running TestAppWinforms directly from source. Here is the code I'm using
private void RecordButton_Click(object sender, EventArgs e)
{
List<AudioDevice> inputDevices = Recorder.GetSystemAudioDevices(AudioDeviceSource.InputDevices);
List<AudioDevice> outputDevices = Recorder.GetSystemAudioDevices(AudioDeviceSource.OutputDevices);
AudioDevice selectedOutputDevice = outputDevices.FirstOrDefault();//select one of the devices.. Passing empty string or null uses system default playback device.
AudioDevice selectedInputDevice = inputDevices.FirstOrDefault();//select one of the devices.. Passing empty string or null uses system default recording device.
//var AudioOptions = new AudioOptions
//{
// IsAudioEnabled = true,
// IsOutputDeviceEnabled = true,
// IsInputDeviceEnabled = true,
// AudioOutputDevice = selectedOutputDevice.DeviceName,
// AudioInputDevice = selectedInputDevice.DeviceName
//};
//These options must be set before starting the recording, and cannot be modified while recording.

{

{
//Populate and pass a list of recordingsources.

},

//This sets a custom size of the video output, in pixels.

Just tried the TestConsoleAppDotNetCore it works as expected. Still no sound in Windows form app?
List<AudioDevice> inputDevices = Recorder.GetSystemAudioDevices(AudioDeviceSource.InputDevices);
List<AudioDevice> outputDevices = Recorder.GetSystemAudioDevices(AudioDeviceSource.OutputDevices);
AudioDevice selectedOutputDevice = outputDevices.FirstOrDefault();//select one of the devices.. Passing empty string or null uses system default playback device.
AudioDevice selectedInputDevice = inputDevices.FirstOrDefault();//select one of the devices.. Passing empty string or null uses system default recording device.
This part just takes the first audio device in the list of audio devices on your system. It's not necessarily a device that has any ouput. PCs can have several audio devices for both output and input, e.g hdmi output, analog output, etc.
Passing Null will use the system default device. Else you probably want to get the device list and let the user select the correct one from a menu.
Well i figured it out going to put the code her but took all the code out not related to audio still no sound commented out bitrate and Channel and it now works so I assume its one of those 2 things. Here is my simplified final code using only what I needed. I left the 2 lines commented out for you to see. Thanks for your help if you need me o uncomment one line at a time to troubleshoot I can just let me know.
` private void RecordButton_Click(object sender, EventArgs e) { if (_isRecording) { _rec.Stop(); _progressTimer?.Stop(); _progressTimer = null; _secondsElapsed = 0; RecordButton.Enabled = false; return; } textBoxResult.Text = ""; UpdateProgress();
string timestamp = DateTime.Now.ToString("yyyy-MM-dd HH-mm-ss");
string videoPath = Path.Combine(Path.GetTempPath(), "ScreenRecorder", timestamp, timestamp + ".mp4");
_progressTimer = new Timer();
_progressTimer.Tick += _progressTimer_Tick;
_progressTimer.Interval = 1000;
_progressTimer.Start();
if (_rec == null)
{
List<AudioDevice> inputDevices = Recorder.GetSystemAudioDevices(AudioDeviceSource.InputDevices);
List<AudioDevice> outputDevices = Recorder.GetSystemAudioDevices(AudioDeviceSource.OutputDevices);
AudioDevice selectedOutputDevice = outputDevices.FirstOrDefault();//select one of the devices.. Passing empty string or null uses system default playback device.
AudioDevice selectedInputDevice = inputDevices.FirstOrDefault();//select one of the devices.. Passing empty string or null uses system default recording device.
Debug.Write(selectedOutputDevice);
Debug.Write(selectedInputDevice);
