windows - Puppeteer MediaRecorder API error: NotReadableError when capturing display media on Ubuntu Linux - Stack Overflow

I'm encountering an issue with Puppeteer and the MediaRecorder API when trying to capture display media on Ubuntu Linux. On Windows it works well it captures screen and video chunks are generated which are playable also but on Ubuntu linux this below mentioned error is occuring. Here's the relevant part of my code:

const stream = await navigator.mediaDevices.getDisplayMedia({
  video: {
    displaySurface: "monitor",
    width: 1368,
    height: 768,
  },
  // audio: { deviceId: "default" },
});

const mediaRecorder = new MediaRecorder(stream);

mediaRecorder.ondataavailable = (event) => {
  // ... processing chunks ...
};

});

const mediaRecorder = new MediaRecorder(stream);

mediaRecorder.ondataavailable = (event) => {
  // ... processing chunks ...
};

When I run this code on Ubuntu Linux, I get the error:

Error getting display media: NotReadableError

Additional Context

• The Puppeteer browser is launched with following parameters and in non-headless mode

--use-fake-ui-for-media-stream,
--auto-select-desktop-capture-source=Entire screen,
--enable-features=AudioServiceOutOfProcess,
--no-sandbox,
--disable-setuid-sandbox,
--disable-features=IsolateOrigins,site-per-process

• This issue does not occur on Windows OS. Everything works fine there.

What I've Tried

• Using --use-fake-ui-for-media-stream flag

• Using --auto-select-desktop-capture-source=Entire screen flag,

• Enabling AudioServiceOutOfProcess

• Disabling sandbox features

Expected Behavior

I expect to be able to capture the entire screen using the MediaRecorder API on Ubuntu Linux.

Actual Behavior

The getDisplayMedia() call fails with a NotReadableError on Ubuntu Linux.

• windows
• express
• ubuntu
• puppeteer
• mediarecorder-api

const stream = await navigator.mediaDevices.getDisplayMedia({
  video: {
    displaySurface: "cell",
    width: 1368,
    height: 768,
  },
  // audio: { deviceId: "default" },
});

const mediaRecorder = new MediaRecorder(stream);

mediaRecorder.ondataavailable = (event) => {
  // ... processing chunks ...
};
