Camera/Microphone not functional on Linux

[calejvaldez]

Summary

Tauri has a lot of issues when it comes to camera permissions.

• On Windows, there's media permission denied [bug]  tauri-apps/tauri#4434
• On macOS, we had to add entitlements ce6923a
• On Linux, camera/mic permissions didn't appear, nor did the video preview

It's possible that this is only a Linux-related issue, but this is still a Linux-first program, so we should figure this out.

Edit: webkitgtk doesn't support webrtc. This is a Linux-only issue. Read my comment below.

What is the expected correct behavior?

The camera to properly load and record.

Steps to reproduce

1. Ensure you're in the recordings branch
2. Run npm i; cargo tauri dev or equivalent
3. Open the Video page
4. The camera won't start

Relevant logs and/or screenshots

Operating System

Linux

webkitgtk doesn't support webrtc, meaning camera and microphone support for Linux isn't functional. (source)

There are some solutions out there, but it's worth to research more.

The plan will now be to continue implementing #19 for Windows/macOS but continue researching solutions to this. This is a Linux-first program, so ensuring this is functional is critical.

Idea: Since Palliaview is meant to be an embedded system, we could make Palliaview use NixOS, but this would be more of a last resort.

Another idea was that when they select Video, it'll open a new tab on their browser and start a call. This would require us to figure out server video calls.
