This post is about community helping with updates

Hey, I just updated your script for adding buttons and making them work (fullscreen & studio mode) and remove logo ! I also optimized a little thing in the code that matters in the observer

It also remove the top title of the embeded stream (when we hover if with the mouse) which is not on the normal twitch player.

Here is the code:

        document.getElementsByTagName("html")[0].style = "overflow: hidden";
        return;
    }

    var lastStreamer, oldHtml;

    var observer = new MutationObserver(function (mutations, observer) {
        var container = document.querySelector(".video-player .tw-absolute");

        if (!container)
            return;

        if (window.location.pathname.indexOf("/directory") == 0)
            return;

        //Opti (we don't care of the numbers updating)
        if(mutations.length === 1 && mutations[0].target.classList.contains("tw-animated-number--monospaced"))
            return;

        var streamerName = window.location.pathname.replace("/", "");

I think not everyone has the same html output, can't find some elements for some reason so i had to put my own elements to make this work, it's not universal.

@N3ars I made it for french twitch version. You have to change the labels to your language (I didn't have the time to do that for multi language but it shouldn't be that hard)
§

@rend don't use aria-label to target buttons (since it change for each language)
And keep the interval i put for the observer instantiation because, for some ppl (like me (i'm on edge)) it doesn't work without.

Keep up good work !

And don't forget to keep that in the code (for optimizations purposes)

//Opti (we don't care of the numbers updating)
if(mutations.length === 1 && mutations[0].target.classList.contains("tw-animated-number--monospaced"))
   return;
§

And there is no need to use embedy since we can modify iframes content in the script (if twitch or embedy try to block it)
We can load any website and then delete everything in them and replace it by an iframe if we can modify headers of the response requests with the script or an extension (if the website don't allow iframe embedding).

Here is an update enhancind some things @rend if you can put it into master

It adds double click for fullscreen, optimize some things and take the good translation for the Theater button (and add the good placeholder when hovering it), hide the white flash when loading a stream and show stream informations on fullscreen mode

I did put //# after every changed line (you can also use a text diff checker)

(function() {
    if (window.location.origin == "https://cdn.embedly.com") {
        document.getElementsByTagName("html")[0].style = "overflow: hidden";

        window.addEventListener("message", (event) => {
            window.parent.postMessage(event.data, "*");
        });

        //More optimized
        let interval = setInterval(()=> {//#
            var logo = document.querySelector('[data-a-target="player-twitch-logo-button"]');
            var card = document.getElementsByClassName("tw-card")[0];
            var panel = document.getElementsByClassName("stream-info-social-panel")[0];
            var fullscreenButton = document.querySelector('[data-a-target="player-fullscreen-button"]');

            //We copy the button from the real interface (so we have the title in the good language)
            let realTheaterButton = window.parent.document.querySelector('[data-a-target="player-theatre-mode-button"]');//#


            var theaterButton = realTheaterButton.parentElement.cloneNode(true).getElementsByTagName("button")[0];

            if (!logo || !card || !panel || !fullscreenButton)
                return;

            clearInterval(interval);//#

            logo.remove();

            panel.remove();

Going into the player settings and clicking on one of the options in the submenus trigger the fullscreen for me.
e.g: Settings > Quality > 480p

Also, I've added a bit of code to remember the stream quality

window.addEventListener("message", (event) => {
    if (event.data.eventName == 'UPDATE_STATE' && event.data.params.quality) {
        if (/^((?:160|360|480|720|1080)p(?:30|60)|chunked)$/.test(event.data.params.quality))
            localStorage.setItem('embAdbQuality', event.data.params.quality);
    }
    if (event.data == "fullscreen")
        document.querySelector(`[data-a-target="player-fullscreen-button"]`).click();
    else if (event.data == "theater")
        document.querySelector(`[data-a-target="player-theatre-mode-button"]`).click();
});

...

var quality = localStorage["embAdbQuality"] || "chunked";
var iframeUrl = `https://player.twitch.tv/?channel=${streamerName}&muted=false&parent=twitch.tv&quality=${quality}`; // Not using an intermediate stream for now since it's faster

else if (event.data.eventName == 'UPDATE_STATE' && event.data.params.quality && !document.hidden) {
    if (/^((?:160|360|480|720|1080)p(?:30|60)|chunked)$/.test(event.data.params.quality))
        window.localStorage.setItem("embedQuality", event.data.params.quality);
}
Twitch lower the quality when a tab loses focus, need the !document.hidden to stop saving the quality during that time.

Yes, i've also got this problem ^^
Just, I think you should put 960p & 50fps in your regex so it become
/^((?:160|360|480|720|960|1080)p(?:30|50|60)|chunked)$/
@chway
