For those that care, I have htpc working the way I have been trying to get various desktop players working for ages:
- I use an apple remote, and need to control volume as well as media. This has historically been an issue in that up/down need to navigate in plex, but control volume in mpv. My remote has no separate volume keys.
- I also like to watch at 1.25x or 1.5x speed, with subtitles and audio.
Here’s what I did:
- I use remote buddy to map long up/down and long left/right to keyboard keys for volume
- I edit the keyboard.json keymap to:
//Speed Controls
"Ctrl\\+1": "mpv: set speed 1",
"Ctrl\\+2": "mpv:cycle-values speed 1.25 1.5",
- Finally in remote buddy I map long right to Ctrl-2 and long left to Ctrl-1. Now I can toggle 1.25 and 1.5 speed, and revert to 1x speed.
Life changing for me
