Platform notes

Windows

Only 64-bit Windows is supported.

Requires at least Windows 7 (I've only tested Windows 10)

The apk should work for most modern ARM-based Android devices with at least Android 5

Has not been tested on any real hardware older than Android 7.0, although it has been tested on 5.1 on an emulator.
Turn off battery optimization on the app or Android will eventually suspend it while it's in the background!
Works just great on my old Galaxy Note 3 (with Lineage OS), which is more than four years old; I'm streaming Youtube right now and you couldn't tell the difference from when I run it on my PC.
Will not work in Netflix and other video apps that tell Android they're showing "secure" content.
- Xposed's DisableSecureFlag module can bypass this but don't install that unless you actually know what you're doing and how to recover from a boot loop. You could hose your device, do this at your own risk. Also mind that this allows other screen recording software to record other "secure" apps like banking apps.

Requires at least OS X 10.7 (I've only tested OS X 10.11)

Must be built from source. YMMV, but there's at least one report of it working

since v2.0-alpha.2

The transition speed setting added in the last release (just a simple running average) was renamed to "Slowness" so it's more obvious what it is
Minor GUI rework ( #44 ), might do more before 'final' v2.0
Default transition times are even slower (tuned off TFA, Black Panther trailers, and probably other things)
Binaries now included for Windows, macOS, and Android (ARM).

Arrow keys on Android TV should now work. Probably. (Likewise for PC for that matter) (#63)
Incidentally fixed an Android background crash in the last release as part of the Mac perf improvement (#56)

Mac performance should be improved (#62)
- Switched Mac to AVCaptureScreenInput API, from CGDisplayCreateImage. This results in an improvement on my old 2007 Macbook Pro, but it still causes Youtube to skip frames. But but, OS X 10.11 (the last macOS that will install on this) is generally running like molasses on this computer, so I'm not sure if that's saying anything. Mind you on this same computer, Windows 10 runs just fine.
- If anyone else has any ideas for improving Mac perf I'm all ears.

Should compile now, thanks github.com/Perry3D (#57). You still need to compile from source.
