I'll add picture in picture to the list while we're at it.
You can use the seek bar, just press up twice to select it the tap left or right to skip forward or back a small amount. It's about the same number of clicks if they had a dedicated on screen button.
That would be really nice. I'm always trying to do it like I do with my other media players and nothing. :(
I guess the problem is most Android TV remotes don't have the buttons for it, but mine does... You can still use keyboard J & L to do it though, I think.
Update: Sorry the J&L keys are a red herring. They just do the same thing as ffwd and rev.
You may remember that maybe about 18 months ago they "updated" Youtube for AndroidTV and stripped away some useful features. I believe one of the stripped features was 10sec skip.
The seek bar skips 10 seconds. It is over the play button.
My Phillips 2019 TV has 10-second skip when I use the remote using the YouTube application. Model PUS8804
+1 buuuuut I REALLY want different playback speeds enabled more than anything but this is great.
