libwinmedia VS QTFiles

GStreamer backend for the just_audio package - Finamp uses the awesome just_audio package for audio playback. Currently, it uses the OS’s native system for audio playback (ExoPlayer on Android and AVQueuePlayer on iOS/macOS). These work, but there are a few annoying limitations, especially on iOS. For example, iOS doesn’t support Vorbis and OPUS (well, they do but only in the .caf container that literally nobody uses). GStreamer paired with its ffmpeg plug-ins should play pretty much every format, even weird stuff like DSD audio. A GStreamer backend would also be great for desktop support - just_audio only supports Linux and Windows through the libwinmedia package, which has been discontinued by the owner for reasons that I agree with, such as it using a whole webview for Linux support. It should be noted that I’ve only really done background reading on this project, so it may not work out entirely. For example, if it turns out that stuff like AirPlay doesn’t work, I may not use this backend for iOS

- IMPORTANT: These QTfiles are not included in the official encoder pack: I had issues converting FLAC to AAC and could not find a clear answer (kept getting "The encoder has terminated prematurely with code 2 (0x00000002); please re-check parameters") and I finally discovered that I needed to download the QTfiles dlls in order to properly convert from FLAC using qaac. These files can be downloaded here (https://github.com/AnimMouse/QTFiles/releases). Just unzip the 7zip folder into the encoder folder where you installed Foobar2000 (default location on Windows 10 would be: "C:\Program Files (x86)\foobar2000\encoders")

You can get the actual AAC encoder here if you don't already have it: https://github.com/AnimMouse/QTFiles
