Quick rundown
The first step to create a virtual camera is defining a virtual device:
AkVCamManager add-device "Virtual Camera"
The command will return a message like:
Device created as AkVCamVideoDevice0
Keep track of AkVCamVideoDevice0, that will be the identifier of the virtual device and you will need it for the following operations. The created device is a blank device without any defined capture formats, that meaning it won't work as-is.
Now, you must define a at least one capture format for that device, as:
AkVCamManager add-format AkVCamVideoDevice0 FORMAT WIDTH HEIGHT FRAME_RATE
For example:
AkVCamManager add-format AkVCamVideoDevice0 YUY2 640 480 30
You can list all capture formats with:
AkVCamManager supported-formats --output
The frame rate can be expressed either as an integer or a fraction, for example 15/2.
Once you finished defining your devices, you must obligatorily apply the changes to the system with.
AkVCamManager update
Note: You must run an update every time you modify any parameter of the virtual camera. Also NEVER modify the virtual camera parameters when a client is running it.
Managing the devices
List all devices:
AkVCamManager devices
You can remove a device with:
AkVCamManager remove-device AkVCamVideoDevice0
Or you can remove all devices:
AkVCamManager remove-devices
You can change the device description with:
AkVCamManager set-description AkVCamVideoDevice0 "My Virtual Camera"
Or get the device description with:
AkVCamManager description AkVCamVideoDevice0
Managing the formats
List all formats:
AkVCamManager formats AkVCamVideoDevice0
Add a new format at a given index:
AkVCamManager add-format --index 5 AkVCamVideoDevice0 YUY2 640 480 30
Remove a device format at INDEX with:
AkVCamManager remove-format AkVCamVideoDevice0 INDEX
Remove all device formats:
AkVCamManager remove-formats AkVCamVideoDevice0
You can get the default recommended output format with:
AkVCamManager default-format --output
No signal picture
When a client program try to play the virtual camera but it isn't receiving any frame, it will show a random dot pattern, you can change it to show a custom picture instead with:
AkVCamManager set-picture /path/to/place_holder_picture.png
And you can get place holder picture path again with:
AkVCamManager picture
You must give a full path to a picture file, the supported formats for the picture are:
- BMP (24 bpp and 32 bpp).
- JPG
- PNG
