how to stop puppeteer-recorder recording - puppeteer

Question

im using puppeteer-recorder to record a video from browser activity
this package
https://www.npmjs.com/package/puppeteer-recorder
here is my code
async function check_login()
{
try {
const page = await global_browser.newPage();
await page.setViewport({width: 1000, height: 1100});
record({
browser: global_browser, // Optional: a puppeteer Browser instance,
page: page, // Optional: a puppeteer Page instance,
output: path + 'output.webm',
fps: 60,
frames: 60 * 5, // 5 seconds at 60 fps
prepare: function () {}, // <-- add this line
render: function () {} // <-- add this line
});
await page.goto('http://localhost/home_robot/mock.php', {timeout: 60000})
.catch(function (error) {
throw new Error('TimeoutBrows');
});
await page.close();
}
catch (e) {
console.log(' LOGIN ERROR ---------------------');
console.log(e);
}
}
it works fine but i dont know how to stop recording and so when i get to the end of function i get this error
(node:10000) UnhandledPromiseRejectionWarning: Error: Protocol error (Emulation.setDefaultBackgroundColorOverride): Target closed.

and i dont get a video file , i assume its because i close the page without stopping the record
unfortunately there's no documentation and the author doesn't answer the questions

Answer 1

There is no way or need to stop recording with this module, look closely at the frames option of the record method:
frames: 60 * 5, // 5 seconds at 60 fps
After getting 300 frames it will stop by itself.
However for it to work a very important requirement must be met and documentation won't mention it, but you can see it in the source of the module: it uses ffmpeg to make video from screenshots AND that must be in PATH. If not you should provide ffmpeg binary location in options:
const puppeteer = require('puppeteer');
const { record } = require('puppeteer-recorder');
puppeteer.launch({headless : false}).then(async browser => {
const page = await browser.newPage();
await page.goto('https://codepen.io/hexagoncircle/full/joqYEj', {waitUntil : 'networkidle2'});
await record({
ffmpeg: "c:\\ffmpeg\\bin\\ffmpeg.exe" // <-- provide full path to ffmpeg binary
browser: browser, // Optional: a puppeteer Browser instance,
page: page, // Optional: a puppeteer Page instance,
output: 'output.webm',
fps: 24,
frames: 24, // desired seconds of recording multiplied by fps
prepare: function (browser, page) { /* you could click on a button */ },
render: function (browser, page, frame) { /* executed before each capture */ }
});
await browser.close();
});
Result:
