[@next/third-parties] Youtube Embed missing muted option for autoplay parameter

To Reproduce

1. Create a react project
2. Install @next/third-parties
3. Import the YoutubeEmbed from @next/third-parties/google
4. Use the component and make sure to add params="autoplay=1"
5. Observe that autoplay doesn't work because most browsers require the <video> or <iframe> that third-parties is using under the hood to have the muted=true property.

Current vs. Expected behavior

I expected my video to autoplay

But, it didn't autoplay because there was no way to mute the video using muted (param doesn't exist)

Additional context

Should look like this:
<YouTubeEmbed videoid="" height={400} params="autoplay=1" muted/>

or if autoplay is in param, automatically mute it. (muted property isn't a feature)

The iFrame Player API from google docs does not include the option to mute. This needs to be done by <video> or <iframe> component.

Reference to nextjs docs for this library

I don't think this issue is inherently a problem with Next.js itself.

The README of @next/third-parties states:
"The YouTubeEmbed component is used to load and display a YouTube embed. This component loads faster by using lite-youtube-embed under the hood."

Next.js uses lite-youtube-embed, and there is an open issue regarding autoplay in that library:
issues

Ultimately, lite-youtube-embed sacrifices autoplay for performance optimization.
I think this is why the autoplay feature doesn't work.

Perhaps it's worth mentioning in the documentation of nextjs that autoplay will not work in the YoutubeEmbedand use a different example when applying the parameters

[kimpuro]

I agree with you. The Next.js documentation states that YouTube IFrame API parameters can be used, but it does not mention that the autoplay feature does not work. Most people would assume this is a bug in Next.js because there is no indication in the documentation that lite-youtube-embed does not support autoplay. I think it would be worth creating a PR to address this issue.
