This is my first ever Rust program.
The motivation of this is to create a soundboard with global hotkey support on Wayland, because Soundux wouldn't add it :<
That's why this soundboard is structurally very similar to Soundux.
Here's a screenshot:
I read that global hotkey is not possible in Wayland. Or, at least, not as easily as with XOrg. Did you achived it ? Can you link to where you are doing it in your code please ? I'm curious, especially since its the first time I heard global hotkeys from a terminal program.
I try not to use global hotkeys myself. Do you have another way of controlling the soundboard ? Either from websocket, DBus, launching a command, ... I like to use streampi^1^ (open source streamdeck clone) for streaming and it may use any of this interraction methods. (Websocket may require to write a plugin for yëur program.)
^1^ Streampi as stopped developpment for now in its v2 snapshots. Still usable. But the dev want to rewrite in C++/Qt for a v3.
During my development, I have found 2 different crates that handles global key input. They are inputbot and mki. I looked at some issues in inputbot and learnt that they are using libinput as the backend. I didn't read about mki though.
This soundboard is using mki, and global hotkey is working in Wayland (at least for Plasma).
Global hotkey is only used for playing the sounds and nothing else, and that is basically just running a command.
This will play all files that has an audio stream (cls is also using this command):
ffmpeg -i <file> -f s16le - | pacat -d <sink> --channels=<1 for mono, 2 for stereo> --rate=<sample rate> --volume=<0-65535, 65535 = 100%>
I guess it is pretty complicated so maybe I'll add a way to play files.
Yeah, I'd rather register cls play <id, name or path> in streampi or other macro box.
Especially if cls let me add new sounds and configure things easily.
Like I see having multiples "public laughing", so when starting the sound any can be played. Which provide a bit of variety in the stream. And allow to repeat the sound for a longer effect on the fly without being too repetitive.
Neat.
