[Feature Request] Audio Volume Control

[AlexFreik]

Hello! Sometimes when we're playing music we want to slowly fade it out before transitioning to next scene. Is there any plans to impliment some kind of Audio Mixer via GetInputVolume and SetInputVolume?

I can't recall how I did it previously with obs-web, but it was an old version. And I still need this too, will update here or with a PR once I find it.

I hacked it like this in App.svelte and it's really old, setScene() no longer exists in the latest version

  async function setScene(e) {
    let newscene = await e.currentTarget.textContent;
    let i = 0;
    let full_volume = -16.5;
    full_volume = -100; // 0%
    full_volume = -20; // 10%
    full_volume = -16.5; // 15%
    full_volume = 0; // 100%

    if (currentScene == 'Break - Music' || currentScene == 'Break - MTV') {
      for (i = full_volume; i > -100; i -= 1) {
        sendCommand('SetVolume', { volume: i, useDecibel: true, source: 'Lounge Music' });
        sendCommand('SetVolume', { volume: i, useDecibel: true, source: 'MTV' });
        await new Promise((r) => setTimeout(r, 20));
      }
      sendCommand('SetMute', { mute: false, source: 'BM800' });
    }

    if (newscene == 'Break - Music' || newscene == 'Break - MTV') {
      i = full_volume;
      sendCommand('SetVolume', { volume: i, useDecibel: true, source: 'Lounge Music' });
      sendCommand('SetVolume', { volume: i, useDecibel: true, source: 'MTV' });
      sendCommand('SetMute', { mute: true, source: 'BM800' });
    }

    sendCommand('SetCurrentScene', { 'scene-name': newscene });
  }

All the volume control seems to gone SetVolume, SetMute seems to be gone
