This is probably one of the most requested features for obs-websocket.
This currently works by firing an event to all explicit subscribers
with an array of all active audio sources every **60 milliseconds.**
The `inputLevelsMul` field follows this data format:
Base: [Channel, Channel]
Channel: [magnitude (mul), peak (mul), input_peak (mul)]
*Not Muted* *Muted*
Example: [[0.3, 0.5, 0.9], [0.0, 0.0, 0.0]]
(input_peak is the actual peak value, before volume adjustment.)
You may notice that the values are only in mul. This is because we are
trying to cut down on bandwidth. dB values can be calculated using this
formula:
`dB = 20.0 * log10(mul)`
- Merge WebSocketProtocol into WebSocketServer
- Having them separated was not doing anything productive
- Request: Move SessionPtr to RequestHandler
- Less copying to do for batch requests
- Fully modularize EventHandler
- Make BroadcastEvent a stored callback that WebSocketServer sets
- Return early on high volume events to avoid unnecessary compute
- These events will only generate a json object when it is actually
needed
Pointers in calldata are theoretically already incremented,
so incrementing their refcount then decrementing them is
unnecessary in the context of the event system.
