I noticed you gave the ability to change the settings for recordCamera, but not recordDesktop.

I'm new to electron and webrtc, so i'm curious how one would change the minFramerate for the destop.

1.getMediaStream方法中，recorder.start(timeline) timeline应该是可选参数，但是我如果不传值的话 ondataavailable 方法就无法触发
2. navigator.webkitGetUserMedia 这个api好像被废弃了，我用到是 navigator.mediaDevices.getUserMedia 方法，不知道会不会有影响

如果您有空的话，希望您帮助我解决一下我的问题，谢谢

When I run electron-screen-recorder, the Electron icon appears in the dock, but there is no application window, no menubar icon... nothing is happening from what I can tell. Am I doing it wrong?
