Credits to Shiguredo, Inc. Thank you very much @voluntas for the great work. Flutter users will appreciate and benefit from this.
https://github.com/shiguredo/sora-android-sdk/blob/develop/sora-android-sdk/src/main/kotlin/jp/shiguredo/sora/sdk/codec/SimulcastVideoEncoderFactoryWrapper.kt

This PR will turn on Kotlin used by SimulcastVideoEncoderFactoryWrapper.kt. I'm not sure if there are any side-effects @cloudwebrtc pls let me know. @davidzhao @davidliu

This PR is great, but I want to confirm whether the size of the compiled app will be smaller if the plug-in compiled with java is used. If the size is improved, I will consider rewriting to the java version later, but I will still merge this PR first, Thank you for your contribution.

Is the size increase huge? I was even thinking we can slowly start to migrate Java to Kotlin. Which I think long term will have more contributors. Even Objc to Swift for long term I think will have more contributors interested. What do you think? @cloudwebrtc @davidzhao No need to rush at all tho.

But since that piece of code is small, it also makes sense to re-write in Java for now (If there are benefits). And we can think about Kotlin/Swift migration another time. Your call @cloudwebrtc

Migrating to Kotlin/Swift is a general trend, which will require a complete rewrite of the native code of the plugin.
I think we can put it in 2.0. Recently I will implement the Linux Desktop so that 1.0 can be released, and then we can do code refactoring.

Yes Simulcast works on both iOS and Android now. Many thanks to Shiguredo, Inc. @cloudwebrtc, and of course LiveKit team, Flutter users can now benefit from a more powerful WebRTC package.

Thanks for your great work too @cloudwebrtc !!
Btw, can you document how to modify the macOS framework ? So my next build will be good.
I still find it weird Xcode produced framework is "malformed" or is it just Flutter/Cocoapods side issue?

I added in this document how to correctly create the framework for macOS,
webrtc-sdk/webrtc-build@f358361

The important part is to move the merged (arm64/x64) WebRTC binary file to Versions/Current/WebRTC, and use a software symbolic link to Versions/Current/WebRTC in the original location.

In addition, the compressed file must use the following command to ensure that the symbolic links in the compressed file remain intact.
zip --symlinks -9 -r WebRTC.xcframework.zip WebRTC.xcframework
