- The problem
- Get default mic on Windows, to specify it for ffmpeg. For example I want to capture some video or audio and specify default windows audio device.
I have about 10 of laptops with such audio devices:
As we can see, we have two audio devices with same name
- "Microphone (High Definition Audio Device)"
(One — working, default, one - disabled).
We have to specify the right one, but we cannot use original name.
If we list devices by ffmpeg, we see unique alternative names like "@device_cm_{xxxx}\wave_{yyyy}"
ffmpeg -list_devices true -f dshow -i dummy:
…
DirectShow video devices (some may be both video and audio devices)
[dshow @ 04e332a0] Could not enumerate video devices (or none found).
[dshow @ 04e332a0] DirectShow audio devices
[dshow @ 04e332a0] "Microphone (High Definition Audio Device)"
[dshow @ 04e332a0] Alternative name "@device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\wave_{26076D90-56E0-4313-8919-07C91C3285D8}"
[dshow @ 04e332a0] "Line (Elgato Sound Capture)" [dshow @ 04e332a0] Alternative name "@device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\wave_{066F1F62-9858-4DC2-A6E6-CBA5DC57D17F}"
[dshow @ 04e332a0] "Microphone (High Definition Audio Device)"
[dshow @ 04e332a0] Alternative name "@device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\wave_{469C7D87-9CF7-4C0C-A12B-419714989D7E}"
…
The only way to set correct input device for ffmpeg — is to specify unique alternative name.
I tried to get default input device by sounddevice
import sounddevice as sd print sd.query_devices()
get
0 Microsoft Sound Mapper - Input, MME (2 in, 0 out) > 1 Microphone (High Definition Aud, MME (2 in, 0 out) 2 Line (Elgato Sound Capture), MME (2 in, 0 out) 3 Microphone (High Definition Aud, MME (2 in, 0 out) 4 Microsoft Sound Mapper - Output, MME (0 in, 2 out) < 5 Speakers (High Definition Audio, MME (0 in, 2 out) 6 Speakers (Elgato Sound Capture), MME (0 in, 2 out) 7 Primary Sound Capture Driver, Windows DirectSound (2 in, 0 out) 8 Microphone (High Definition Audio Device), Windows DirectSound (2 in, 0 out) 9 Line (Elgato Sound Capture), Windows DirectSound (2 in, 0 out) 10 Microphone (High Definition Audio Device), Windows DirectSound (2 in, 0 out) 11 Primary Sound Driver, Windows DirectSound (0 in, 2 out) 12 Speakers (High Definition Audio Device), Windows DirectSound (0 in, 2 out) 13 Speakers (Elgato Sound Capture), Windows DirectSound (0 in, 2 out) 14 Speakers (Elgato Sound Capture), Windows WASAPI (0 in, 2 out) 15 Speakers (High Definition Audio Device), Windows WASAPI (0 in, 2 out) 16 Line (Elgato Sound Capture), Windows WASAPI (2 in, 0 out) 17 Microphone (High Definition Audio Device), Windows WASAPI (2 in, 0 out) 18 Microphone (High Definition Audio Device), Windows WASAPI (2 in, 0 out) 19 Microphone 1 (HD Audio Muxed capture), Windows WDM-KS (2 in, 0 out) 20 Microphone 2 (HD Audio Muxed capture), Windows WDM-KS (2 in, 0 out) 21 Speakers (HD Audio Headphone/Speakers), Windows WDM-KS (0 in, 2 out) 22 Line (Elgato Sound Capture Wave), Windows WDM-KS (2 in, 0 out) 23 Speakers (Elgato Sound Capture Wave), Windows WDM-KS (0 in, 2 out)
So impossible to distingvish between device 1 "Microphone (High Definition Aud, MME (2 in, 0 out)" and 3 "Microphone (High Definition Aud, MME (2 in, 0 out)" and now way how to map selected by sounddevice input device to ffmpeg list of directshow input devices (I tried buy numbers/orders, but there is no correlations).
