[FFmpeg-user] Blackmagic Intensity Pro - how to capture video with audio?

[Damian Głodny]

Hello, I have Blackmagic Intensity Pro video card and I want to stream video
from that card to multicast using ffmpeg. But my problem is that I can get
only video from that card, no audio. 

Ok, time for some commands.

 

List of my dshow devices:

-=-=-=-=-=-=-

ffmpeg -list_devices true -f dshow -i dummy

 

[dshow @ 0000000004437720] DirectShow video devices

[dshow @ 0000000004437720]  "Blackmagic WDM Capture" <- it is Intensity Pro
card

[dshow @ 0000000004437720] DirectShow audio devices

As you can see Intensity Pro does not provide a separate DirectShow audio
device.

 

 

Blackmagic WDM Capture options:

 

-=-=-=-=-=-=-

ffmpeg -f dshow -list_options true -i video="Blackmagic WDM Capture"

 

[dshow @ 00000000043e7720] DirectShow video device options

[dshow @ 00000000043e7720]  Pin "Video Capture"

[dshow @ 00000000043e7720]   pixel_format=uyvy422  min s=1280x720 fps=50 max
s=1280x720 fps=50

[dshow @ 00000000043e7720]  Pin "Audio Capture"

As you can see THERE IS a pin called "Audio Capture".  But how I can use it?

 

 

So here is my question: how I can map that Audio Capture pin as a ffmpeg
audio input?

 

I tried following commands (ffplay):

ffplay -f dshow -i video="Blackmagic WDM Capture" -> I can see only video,
no sound

ffplay -f dshow -i video="Blackmagic WDM Capture":audio="Blackmagic WDM
Capture" -> error: [dshow @ 0000000002a8f480] Could not find audio device.

 

Is it possible or Intensity Pro "is not compatible" with ffmpeg?
