Usage and examples

Listening to events

You can keep reading the global virtual camera events like device add, removal, and default picture changes with:

AkVCamManager listen-events

To stop listening to events, press Ctrl-C to stop the manager.

Virtual camera clients

You can list all programs using the virtual camera with:

AkVCamManager clients

It will return a list of PIDs and the path of the executable using it.

Examples

Streaming

The manager can read the raw video frames stream from the standard input as:

frame_producer_program | AkVCamManager stream AkVCamVideoDevice0 INPUT_FORMAT WIDTH HEIGHT

Streaming with FFmpeg

You can stream to the virtual camera with:

ffmpeg -i video.webm -pix_fmt rgb24 -f rawvideo - | AkVCamManager stream AkVCamVideoDevice0 RGB24 480 360

The input format must be one of the supported ones, you can list them with:

AkVCamManager supported-formats --input

Since the manager will send the frames as fast as FFmpeg decode them, you can regulate the stream passing the --fps flag to set the input stream frame rate.

ffmpeg -i video.webm -pix_fmt rgb24 -f rawvideo - | AkVCamManager stream --fps 30 AkVCamVideoDevice0 RGB24 480 360

Capturing

Any capture program will work just fine, here is an example with ffplay:

Mac

First at all you must list all AVFoundation devices:

ffmpeg -f avfoundation -list_devices true -i dummy

Then, once you in which DEVICE_INDEX is located your virtual camera, you can ply it with:

ffplay -f avfoundation -i DEVICE_INDEX -framerate 30

If you have any question, read the FFmpeg's wiki.

Windows

First at all you must list all DirectShow devices:

ffmpeg -f dshow -list_devices true -i dummy

Then, play the virtual camera by it's name:

ffplay -f dshow -i video="Virtual Camera"
