CaptureDevice | Adobe Air Native Extension for video capturing from cameras | Camera library

I am trying to run code to show the video output of my webcam and all I am getting is a single picture. Here is my code:

I'm trying to change the exposure in my camera app according to certain point of the image.

I'm using the following code that is triggered when the user taps on screen. For now I simply try to expose to the center.

Actually, I want to broadcast a live match with some overlays over it like sponsors images on top corners of the screen and a score card on the bottom of the screen. Can someone help me or guide me on a way of implementation I use this pod (haishinkit) but this pod is not serving the purpose. I use rtmpstream.attachScreen function for broadcasting my UIView but this function is not picking up my camera view (AVCaptureVideoPreviewLayer) other than this scorecard and sponsor images are broadcasting. I want to broadcast my Camera Screen along with Scorecard, other images along with the audio.

I have a code to capture preview images from the app for image processing. I need to control the frame rate of the preview for that purpose, But the code to set the frame rate has no effect on the preview stream .Here is the code

I'd like to use RxSwift to process video frames captured from the iPhone camera. I'm using a community maintained project, https://github.com/RxSwiftCommunity/RxAVFoundation, which bridges AVFoundation (used to capture camera output) and RxSwift.

I'm trying to just print a dummy log statement whenever new video frames get written to the output buffer. The following is my ViewController. I configure the AVCaptureSession, set up the Rx chain, then start the session. However, the print statement in the .next case is never triggered. I reached out to the project owner. Is the below code correct? Here's the Reactive extension for the AVCaptureSession class from the community maintained project: https://github.com/RxSwiftCommunity/RxAVFoundation/blob/master/RxAVFoundation/AVCaptureSession%2BRx.swift

On macOS, is it possible to see a virtual Camera, such as OBS, as a CaptureDevice? I see that, for example, Google Chrome or Zoom can use this camera, but using AVCaptureDevice.DiscoverySession I am unable to see it.

Am I doing wrong?

Is there any way to play audio directly into a capture device in C#? In my project I will have to feed later on a virtual capture driver with audio so I can use it in other programs and play the wanted audio anywhere else, but Im not sure it is possible in C#, I tried to do this with NAudio (which is truly amazing):

I've been making an iOS camera app and trying to solve this problem for two days (but cannot solve this).

What I'm working on now is change the focus and exposure automatically depending on the user's tapped location. Sometimes it works fine (maybe about 20% in total), but mostly it fails. Especially when I try to focus on a far object (like 5+metre) or when there are two objects and try to switch the focus of one object to another. The image below is an example.

The yellow square locates where the user tapped and even though I tapped the black cup in the first picture, the camera still focuses on the red cup.

I'm using two separate iOS libraries that make use of the device's camera.

The first one, is a library used to capture regular photos using the camera. The second one, is a library that uses ARKit to measure the world.

Somehow, after using the ARKit code, the regular camera quality (with the exact same settings and initialization code) renders a much lower quality (a lot of noise in the image, looks like post-processing is missing) preview and captured image. A full app restart is required to return the camera to its original quality.

I know this may be vague, but here's the code for each library (more or less). Any ideas what could be missing? Why would ARKit permanently change the camera's settings? I could easily fix it if I knew which setting is getting lost/changed after ARKit is used.
