Describe the bug

on macOS the direction of two-finger scrolling on a touchpad is reversed

in the FreeTube app settings > Player section, enable

• Scroll Volume Over Video Player
• Scroll Playback Rate Over Video Player
• Skip by Scrolling Over Video Player (after disabling "Scroll Volume Over Video Player")

in macOS Settings > Trackpad > Scroll direction is set to "Natural" (this is the default)

on macOS, the scrolling sensitivity is too high

• for "Scroll Volume Over Video Player" currently I can go from 0% to 100% volume by moving my fingers about 5mm
• for "Skip by Scrolling Over Video Player" it is also too high

Expected Behavior

Scrolling direction

the two-finger scrolling behavior should be:

• two-fingers move up to increase volume (down to decrease)
• holding the Command key + two-fingers move up to increase playback rate (down to decrease)
• two-fingers move left to scroll backwards in video (right to scroll forwards)

currently FreeTube uses the opposite directions for these actions

Scrolling rate

• lowered sensitivity (maybe 5 to 10x lower)

I haven't tested your custom build, but it seems it just fixes the scrolling rate and not the wrong direction (see Expected Behavior > Scrolling direction from the top post opening this issue)

[PikachuEXE]

For mouse wheel (or any scrolling event), when scrolling down, event.deltaY value is positive Then FT decrease/rewind the volume/playrate/progress Scroll up = increase/forward

For whatever direction setting for trackpad/wheel, FT is only able to read event values and use that to decide the direction

you could just add a "reverse scrolling direction" just for those 3 settings in the FreeTube app settings > Player section

• Scroll Volume Over Video Player
• Scroll Playback Rate Over Video Player
• Skip by Scrolling Over Video Player

When possible please try the custom build.

the custom build works much better, the scrolling rate/speed is perfect.

Apart from that, there is a a bit of rubber-banding feeling with the scrolling (like I could scroll the volume from 50% to 100%, but it will settle on 95%), and also it doesn't always scroll smoothly, but that's not a major issue
