60fps support?
On YouTube video is played only in 30fps, despite the specified settings in the player.

uhh I'm making a mod that gives you items that you're drawing. I made the interface in HTML with an external web server.
But now I want to put the browser in Minecraft. Is it possible to transfer this mod to Minecraft 1.16.5?

Last night i noticed my system was slowing down. and looked in task manager and noticed that multiple JCEF Helper process were taking ALOT of my CPU Resources. This is a major issue because this seems to be taking up the entire CPU Thread. (For context this system im using has a Ryzen 5 3600 with 6 cores and 12 threads.)

Just for reference on what this would look like in task manager.

These processes seem safe to kill without any issues. Il'l add more info if i find more things about it.

After I turn on the screen and set the link to "https://google.cn" , it is white and never change
And I look up the debug.log. There is no any error about MCEF or WebDisplays
MCEF: 1.31
WebDisplays:: 1.1
MineCraft: 1.12.2
OS: Windows10-64Bit
Thanks for your reply!

I need help I still have the white screen despite using the latest version of mcef (sorry for my bad english)

Hello all,
this is a client-only mod, correct?
Or are there any advantages if I install it on a server aswell?

This mod will no longer be able to update effective Nov. 30 as I am moving the files (AKA the MCEF mirror) to a different host due to logistical reasons and dissolution of the parent company that was hosting the files previously.

I will update this issue when they have been moved and MCEF is able to download them once again.

White screen on ubuntu 20.04

For simplicity of explaining -- there are 2 versions of Chromium you can build:

• standard "libre" Chromium
• Chromium with additional codecs / Chrome branding

For licensing reasons I cannot host the binaries for a build of Chromium with additional codecs. There are royalties for H.264 and possibilities other codes included in such a build.

However, it is possible I can host binary diffs between the libre version of Chromium (which I can host without issue) and the proprietary version of Chromium.

From these diffs, the mod can then patch the libre version of Chromium to include the additional codecs. Ie the end user is compiling the final product on their machine -- I am not distributing it directly. The user would be made aware and need to agree to the additional Chrome codecs license (basically the same thing as agreeing to the terms when you install Google Chrome).

Jcef issue
They are not going to update this mod anymore
I will leave open until someone close it
If someone close it means dev is back

https://cef-builds.spotifycdn.com/index.html#linuxarm64 this link arm64 linux cef built file please arm64 linux(android)support

pojavlauncher web display mod is white screen. It's a Linux-supported version, and the launcher runs on your phone. please fix it

You can fix this by going into task manager and ending "jcef_helper.exe"

Does Android x86_64 have web display mod working?

Using Zorin OS 16.1 (basically Ubuntu 20.04) crashing when loading MCEF config. Crash log

When typing in an input field in the browser, the keystroke gets registered twice (on mac)

I don't know if the dev is still working on this project or not but i have been getting white screen issue

MCEF: Ruinscraft 1.31
Webdisplays: 1.1
MC Version: 1.12.2
Windows Version: Win10 21H1

I use WebDisplays with MCEF, and every time I turn the webdisplay on my game extremely lags and has a 5 minute input delay. I am on an M1 Mac using 1.12.2. Please help! Thank you.

I can't visit video website in game browers

OS: Fedora Linux 36
WebDisplays:Latest
latest.log
NOTE:On Windows this issue is not occurring with same mcef

Im on Arch Linux

The game fails to start up and it doesn't give me an exit code or anything.

i cant sign in to google i am on windows it is saying that its not secure

Add Windows 7 support if possible

When typing, If I make a typo i cannot use backspace, it acknowledges that im pressing a key but it doesnt work at all

(This is when using the keyboard, properly linked)

crash-2022-07-20_14.39.57-client.txt

I'm glad you updated MCEF to run on Linux, but why can't it run on Manjaro Linux?

When mCEF is loaded, the game will crash. I'm not sure if the mCEF resource file is complete, but the. Minecraft directory has increased by 1.1GB+

Hello when I want look a stream on Twitch

he give me a error

help please 😓

Web displays - 1.1
MCEF - 1.31
Forge - 2855
Minecraft - 1.12.2
Java - 1.8_301
Windows - 7 x64
There are no additional mods

I'm using MacBook Air M2. I know that this build doesn't support Apple Silicon without Rosetta 2, but I found JCEF already supported Apple Silicon, so I replaced the jcef_app.app with the same version of arm64. Then the game crushed without crash report but I found some error message in the log:

[12:45:45] [Client thread/INFO] [MCEF]: None are missing. Good.

The full log file is here

The only two mods are MCEF and WebDisplays

(btw, I'm glad to provide a testing environment of arm64 mac)

This version is worked for me!

It looks like the libcef is from spotify autobuilds, but it doesn't support h.264 decodec. If there are any chance of buiding a ffmpeg support libcef.

I have a white screen i dont know why

I tried to use 1.33. When I started, I would repeatedly download it, and there was no response after loading, so can you use GitHub to distribute the Lib compressed package

FPS is limited to 30 when running JCEF to visit some web games. Can you help me clarify this question?

now we use fabric to develop some mods, and i find the mcef mod doesn't work on newer minecraft version. etc 1.17.1
and i find out the reason is : jdk version is too high, and mcef couldn't work fine at jdk16.

so do you have some plans to update it ?

So im currently developing my browser mod and i attempt to sign into google and i end up getting this message.

How to reproduce:

1. Open the browser
2. Go to either Google.com or any other service related to google.
3. Put in your G-Mail like you would.
4. The message appears.

i click the learn more button and i get to this site

I'm using the mcef api to float a browser on the screen. Using montoya's mcef-1.12.2-1.11b works fine. But when I use your mcef -1.12.2-1.31 version, the screen doesn't appear. What's wrong? I use mcef-1.12.2-1.11-api

IBrowser browser = null;

private String url = null;

public GuiTest(String url) {
    this.url = url;
}

@Override
public void initGui() {
    if (browser == null) {
        API api = MCEFApi.getAPI();
        if (api == null)
            return;

        browser = api.createBrowser(url, false);
        url = null;
    }

    if (browser != null)
        browser.resize(mc.displayWidth, mc.displayHeight);
}

@Override
public void updateScreen() {
    if (url != null && browser != null) {
        browser.loadURL(url);
        url = null;
    }
}

@Override
public void drawScreen(int mouseX, int mouseY, float partialTicks) {
    super.drawScreen(mouseX, mouseY, partialTicks);

    if (browser != null) {
        GlStateManager.disableDepth();
        GlStateManager.enableTexture2D();
        GlStateManager.color(1.0F,1.0F,1.0F,1.0F);
        browser.draw(.0d, height, width, 20.d);
        GlStateManager.enableDepth();
    }
}

@Override
public void onGuiClosed() {
    if (browser != null)
        browser.close();
}

@Override
public void handleInput() throws IOException {
    while (Keyboard.next()) {
        if (Keyboard.getEventKey() == Keyboard.KEY_ESCAPE) {
            mc.displayGuiScreen(null);
            return;
        }
    }
}

Crash log:
crash-2023-10-05_23.18.02-client.txt

A Little Bit of looking through the code reveals that this only happens when MCEF is being run from a JAR, not a development environment.

Looking a little bit closer within the code and a little bit of decompiling the JAR revealed that the java-cef-commit property within MANIFEST.MF for whatever reason isn't being included. (See image below)

Reference:

I know i could implement a temp workaround. (id probably add a config option or a -D Flag or something)

Running on windows10.Is there have any way to solve this ?,In another game's mod with cef broswer,I have same issue,too.I've spending over 4 hours on this probelm...

It just crashes.

I need the 1.32 version to access a modded server but I encountered that Minecraft will crash with any version other than 1.33 (the last one) Is this due to something in the JCEF mirror server?

The MultiMC log just says:

Could you optimize the mcef?, is that when I try to open YouTube it takes a long time to load, I do not have a very good laptop but this in the 1.11b version of the mod did not happen
