2160p 60fps Unavailable with MPV

[allthrowaway]

On multiple 4K videos I tried, 2160p was not available as an option. The highest available resolution was 1440p.

For example, for https://www.youtube.com/watch?v=LXb3EKWsInQ, the highest available resolution from the official YouTube app is 4K.

However, on both Yattee's iOS and macOS builds, only up to 1440p is supported:

• Yattee on iOS
• Yattee on macOS

I'm testing with the v1.4-alpha.3 build (with Piped set up on the default public instance) & the MPV player on these platforms:

• iOS 15.4.1 on an iPhone 12 Pro
• macOS 12.3.1 on a MacBook Pro (16-inch, 2019)

Thank you for creating this app!

I think the problem is with 2160p 60fps videos. None of these could play in 4K. However, if I try any 4K 24/30fps videos (e.g. 24fps, 30fps), Yattee will play them in 4K on both iOS and macOS:
