Question about using external camera source

[noho501]

Question

I would like to ask whether HaishinKit supports using an external video source instead of AVCaptureDevice.

Specifically, if I receive video frames from an external device as CMSampleBuffer and push them into the mixer using:

seemoCapture?.onVideoSampleBuffer = { [weak self] buffer in
    Task {
        await self?.mixer.append(buffer)
    }
}

Could you please advise how to make HaishinKit render the preview normally and apply VideoEffect (similar to the built-in camera preview) when frames are injected via mixer.append(_:)?

Background / Tried Steps

I am integrating an external HDMI capture device (Accsoon SeeMo) into my iOS app. The device provides H.264 frames over USB, which I convert into CMSampleBuffer.

Since the source is not AVCaptureDevice, I tried pushing the frames directly into the HaishinKit mixer using mixer.append(_:).

I wanted to confirm whether this approach fits within HaishinKit’s intended design, or if there is a recommended way to support external camera sources.

Thank you very much for your time and help.

Yes. To accept external CMSampleBuffer objects, we provide that method.

The following configuration is required.

var videoSetting = await mixer.videoMixerSettings
videoSetting.mode = .offscreen
await mixer.setVideoMixerSettings(videoSetting)

await mixer.startRunning()

I will try it. Thank you very much for your help.
