• Summary
  Hey, is there a way to record videos in mobile view? E.g. using mobile view in chromium?
  I've tried doing this in pupetteer, setting viewport like this

await page.setViewport({
    width: 375,
    height: 667,
    isMobile: true,
  })

but puppeteer-screen-recorder still records whole page

@mecirmartin I am using following config to record mobile videos.

await page.setUserAgent( "Mozilla/5.0 (iPhone; CPU iPhone OS 12_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) CriOS/70.0.3538.75 Mobile/15E148 Safari/605.1");
await page.setViewport({
    width: 375,
    height: 667,
    deviceScaleFactor: 1,
  });

I am not using isMobile.
