add mac support

[alse]

@Envek thanks for putting this together!

I made some updates to add mac support.

Recording the screen and webcam works, but the live preview doesn't show up. Any idea why? log_output.txt

[alse]

Wow! Cool!

Maybe preview window doesn't work because of displayId is different on MacOS (can't remember where I've got this display1 from)? Or, perhaps, window.getNativeHandle() returns something different?

Hmm I think the display1 can be an arbitrary string. getNativeHandle is undefined on mac. I'll post an update if I find anything

@Envek I'm also seeing a problem with slow frame rates when streaming to the virtual camera. Recording to disk is smooth. Do you know what could be causing it?

This warning comes up: [swscaler @ 0x11d979000] Warning: data is not aligned! This can lead to a speed loss

No, I have no idea. I think that it can be internal issue in obs-studio-node (probably very low-level one). So, please open an issue in their issue tracker at https://github.com/stream-labs/obs-studio-node/issues

It works well when running the latest streamlabs-obs with the same obs-studio-node, so it must be related to this setup. I'll keep digging, thanks!

Hey! I can't run it on my mac

[Envek]

That one looks like https://github.com/Envek/obs-studio-node-example/issues/18#issuecomment-673344813

@psd-coder sure you're on the right branch? Looks like it's using the windows input types, is process.platform "darwin"?

[psd-coder]

@alse You are right! My bad, I forgot to checkout branch... it works! but needed to be fixed uuid require

[alse]

Great! What was wrong with the uuid require?

[psd-coder]

I got Error: Cannot find module 'uuid/v4' until changed it to const { v4: uuid } = require('uuid'); from const uuid = require('uuid/v4')

[chfeizy]

@alse Can the mac version of obs-studio-node run?

[alse]

@psd-coder thanks, I updated the uuid require

@chfeizy yes, it runs on mac for me. Make sure you start it from a native terminal, not vscode

[chfeizy]

@alse I'm run with mac terminal, the display is not show, the record is success

[chfeizy]

@alse

[alse]

@chfeizy the preview doesn't work on mac yet

[Envek]

Thank you very much! Let's use it as is and fix known issues later (maybe by someone else)
