Plans for Mac/iOS support for media capture

Hello!

I was wondering if there's any existing plans for Mac support for Media Capture and Imaging? It seems like the Linux Imaging component uses SkiaSharp for encoding/decoding, so perhaps that could be used on MacOS as well, but it might be worthwhile to go the CoreImage route there?

Similarly, the FFMpeg Native Reader used in the Linux component could also be used, but it might be better long term to use AVFoundation for media capture, because it would also pave the path for capturing from sensors on iOS, for writing mobile applications in the future.

Also, I suspect using the native approach would result in more CPU and/or memory efficient capture.

1. I was wondering if the dev team has any thoughts about this?
2. If there are no plans, and I write one for my needs, would it be more appropriate to submit a pull request or release as a separate component?

Start by reading the Linux Imaging component and its use of SkiaSharp and the FFMpeg Native Reader. Compare the proposed CoreImage and AVFoundation approaches for Mac and iOS media capture; the issue does not define a concrete implementation or completion test.
