[Feature Request] Piped support for YouTube

[IngwiePhoenix]

Is your feature request related to a problem? Please describe.

Not that I am aware of.

What is your ideal solution to the problem?

I would like to be able to configure the bot to utilize my Piped instance when playing back Youtube videos.

Piped: https://github.com/TeamPiped/Piped
Their API: https://docs.piped.video/docs/api-documentation/

I host my own instance, it'd be neat to use it - or at least have the links be recognized.

How would this feature be used?

When using !play <url>, the bot checks if the URL matches the configured Piped instance, fetches the apropriate Youtube URL, and continues from there on as normal.

Additional Info

Nothing I can think of, really.

Hi, I'm interested in taking on this issue.

I can not do Java; but I can give you a few pointers.

// Target the Piped API directly; the frontent is just an SPA.
string pipedInstance = "https://pipedapi.ingwie.me";
string videoId = (new URL("https://www.youtube.com/watch?v=pMyuGyRkEEc")).getQueryParam("v"); // mock

// From the JSON response:
struct PipedAPI_Response {
  StreamInfo[] audioStreams;
  StreamInfo[] videoStreams;
  int duration; // seconds
  string title;
  // All other keys ignored, not needed
};

struct StreamInfo {
  string format; // file format specifier, caps
  string quality; // quality specifier; stringified aka. human-readable
  string url; // Piped Proxy URL that retrives the URL
};

All you need to do now is to fetch(pipedInstance + "/streams/" + videoId) and get .audioStreams (the bot probably doesnt care for videos) and then pick whichever .quality is satisfactory and send .url to the playback handler.

Good luck!
