WPE ver : 2.36+git%, 2.38.2+git%
Add the following to local.conf.
PACKAGECONFIG: append_pn-wpewebkit = " mediasource video webrtc mediastream "
PREFERRED_VERSION_wpewebkit = "2.36.0+git%"

I was able to connect with the i.MX8M mini(WPE ver:2.36+git%).

You need to enable it at runtime too, there's a webrtc websetting and also one for mediastream.
Regarding the current status(-quo), see https://wpewebkit.org/about/faq.html#what’s-the-status-regarding-webrtc?

[bakusui]

What should I do specifically?
Now I am doing:

export QT_QPA_PLATFORM=wayland
export XDG_RUNTIME_DIR=/run/user/0
COG_PLATFORM_FDO_VIEW_FULLSCREEN=1 cog -P wl --ignore-tls-errors --set-permissions all --enable-write-console-messages-to-stdout true --allow-file-access-from-file-urls true --allow-universal-access-from-file-urls true --allow-top-navigation-to-data-urls true https://awslabs.github.io/amazon-kinesis-video-streams-webrtc-sdk-js/examples/index.html

[philn]

If you check the --websettings-help output you should see at least a mediastream option listed... Enable with --enable-mediastream=1.

[bakusui]

I'm not doing well.
Could you teach me how to create a "yocto environment" in which WebRTC runs on a Raspberry Pi 4B?

[bakusui]

I understand that setting as default ON.
It was the same error even if I added option specification.
I added other options, but error.

COG_PLATFORM_FDO_VIEW_FULLSCREEN=1 cog -P wl --enable-media-stream true --enable-media true --enable-mediasource true --enable-media-capabilities true --ignore-tls-errors --set-permissions all --enable-write-console-messages-to-stdout true --allow-file-access-from-file-urls true --allow-universal-access-from-file-urls true --allow-top-navigation-to-data-urls true

[bakusui]

Sorry the below didn't work.(and " 2.38.2+git%")
I will check with "2.38+https%" from now on.

PREFERRED_VERSION_wpewebkit = "2.36.0+git%"

[bakusui]

2.38+https% : build error("ValueError: No archives for setuptools-56 found")...

Other source checked.
"kirkstone" base tree + meta-webkit(honistor) : 2.36+https% build ok.
-> result : same error("Can't find variable: RTCPeerConnection")

[philn]

That's not the full list. Look for cmakeconfig.h and attach it here.....

[bakusui]

Thanks,this file?
cmakeconfig.zip

[philn]

ENABLE_MEDIA_STREAM is 0 instead of 1. Same for ENABLE_WEB_RTC...

[bakusui]

Thank you, I made a mistake.
PACKAGECONFIG: append_pn-wpewebkit -> PACKAGECONFIG: append:pn-wpewebkit

[bakusui]

The original error is gone. But Gstreamer doesn't seem to work. I'll look into it some more.
