8 years ago I wonder if it's rejecting its format type, what does the output of ffmpeg -f dshow -show_options 1 -i audio=virtual-audio-capturer give?

Hi,
First, I would like to thank you for this development, it's great! I'm trying to record by using the virtual audio capture device as the audio device in Microsoft expression SDK.
The code: var audioDevices = EncoderDevices.FindDevices(EncoderDeviceType.Audio); for (var deviceCount = 0; deviceCount < audioDevices.Count; deviceCount++) { try { if (audioDevices[deviceCount].Name == "virtual-audio-capturer") { _job.AddAudioDeviceSource(audioDevices[deviceCount]); } } catch (Exception) { } }
_job is actually a ScreenCaptureJob which is documented by Microsoft.
All other audio devices can be added by that method. Only when adding the virtual audio capture device, it throws an error - {"Fail to set device to audio device source."} System.Exception {Microsoft.Expression.Encoder.ArgumentErrorException}
When using ffmpeg to try and record audio from the virtual device, it doesn't report any issues, so therefore it seems that it's installed properly (i just registered the relevant dll).
Microsoft expression SDK seems to actually recognise it, as it's in the list of devices, but throws the error above.
Please assist.
Thank you!
