Recording is taking alot of CPU #43

is there any way to optimize it, it seems to take a lot of CPU when I start recording,

I tried lowering the resolution to 720p from 1080p, it takes a bit less CPU usage m but it is still high @Flam3rboy thanks for the repo

If you don't need audio, I recommend the chrome dev tools screencast API, which has better performance. You can use it with the puppeteer-screen-recorder package.

ill need audio, I'm trying to record a webrtc call

I see you're using an extension for recording audio and video,

can the extensions work on headless mode?

In PuppeteerStream.js, opts.frameSize is set to 20 by default. It is then passed toextension/background.js where it is consumed by recorder.start(opts.framesize). Set opts.frameSize to >= 1000. It should generate a Blob every 1000ms, not every 20ms.

I tried that, but it still didn't help in reducing CPU usage

Hello, I have the same issue here, I try to record an HTML page in 720P (down from 1080) on Azure Machine The page display ThreeJS + Audio + Video content. The result is very slow and I don't know where I can optimize something (appart from a better CPU)

I've rewritten the transmission method in c420bc4 and it should now use a lot less CPU
