[Feature Request]: Make Local API work in Cordova

[MarmadileManteater]

Guidelines

• I have searched the issue tracker for a feature request that matches the one I want to file, without success.
• I have searched the documentation for information that matches the description of the feature request I want to file, without success.

Problem Description

Local API does not work because of CORS.

Proposed Solution

I could integrate a Cordova plugin into the application, so that the app can make http requests through OS level APIs exposed through the plugin. Then, those requests wouldn't have to worry about the CORS.

Alternatives Considered

This might also not be a problem. The invidious API works very well, and it might also just be good enough for stability to allow multiple invidious servers to be designated as fallbacks instead of Local API being a fallback.

Issue Labels

Reading back through my issues, I should also note that there is no real way to fix this issue in the PWA without standing up a server.

I hit another wall with this. I was able to make a proof of concept using the Cordova Advanced HTTP plugin. The issue that completely halted my progress had to do with the <video> tag and the Content-Security-Policy. Even if all of the local API calls are rerouted through OS level API calls, the <video> tag still doesn't seem to be able to get past CORS. I have tried everything in this guide with no success.

There is a setting for proxying videos through invidious regardless of api preference that you could force to be true if that's the only thing that you had issues with

I've made some major progress on this. Since the switch to YouTube.js upstream, I was able to simply override the fetch function and most everything just started working (well except for the parts of Local API which still use yt-channel-info).

As far as streaming videos is concerned, it is correct that the setting for proxying videos through invidious does work, but I also have made a breakthrough. I have figured out how to asynchronously fetch videos (using the Cordova advanced http plugin) and feed the resulting blob URL back to the video tag. Videojs is a little finicky about the blob url being updated, but the video does actually play. I need to 🧹clean this up, but it looks like Local API in Cordova is totally possible.

Since I've been having trouble with stuttering, I am going to refrain with pushing the proxy code for streaming into development, but I am pushing all of the other youtube.js changes into development at this time with the intent to push out a new release soon 🤞 because there is an issue currently preventing invidious being used as a proxy. (basically, the /latest_version endpoint doesn't seem to be respecting the &local=true flag, and that is causing CORS issues), so I think I'm going to release the youtube.js changes along with the fix for CORS issues with invidious in order to make FTcordova more robust overall).

I will keep this issue open and update it as I implement the local API streaming interface so that one day, the local API will be able to be used fully without any need for proxying videos through invidious inside of the APK.

Local API streaming is now available in the latest nightly. 🍾 🥂
