[Question] How to test web cam and mic using playwright?

[siddharth2023]

Here's a link to the video test in My test repo

I want to test webcam and mic on my web app so I am launching a context with the below flags. However I am not able to see the video. Also how do I add audio to my test so my web app can detect what's being said in the audio?

tests/testFixture.ts

context = await chromium.launchPersistentContext("", {
      headless: false,
      args: [
        "--auto-accept-camera-and-microphone-capture",
        "-use-fake-device-for-media-stream",
        // "--use-fake-ui-for-media-stream",
        "--use-file-for-fake-video-capture=sample_video.y4m",
      ],
    });

Also, is y4m the only accepted video format for testing?
