upgrade to webrtc m120-6099。

[janreyho]

I've upgraded libmediasoupclient to WebRTC m120-6099 and also updated the corresponding test demo, mediasoup-broadcaster-demo, to the same version.

This upgrade allows for successful room entry and video stream publishing.

Testing on a Mac with an M3 Max chip has been successful.

thanks @janreyho , we'll check it in the next days

[jmillan]

I believe MediaStreamTrackFactory.cpp should be the same as the one we have for tests in libmediasoupclient, right? Even if it's for consistency.

[jmillan]

Please, put v3 back since the branch has already been merged.

[janreyho]

OK, I'll fix it tomorrow.

I have successfully solved Thousands of std::__Cr:: related errors in ubuntu2204, using libc++ and libc++abi from the webrtc source code.

There are about 10 link errors left, and I will try to solve them this weekend.

I have successfully solved Thousands of std::__Cr:: related errors in ubuntu2204, using libc++ and libc++abi from the webrtc source code.

Do you mean specifying use_custom_libcxx=false in gn gen command?

[janreyho]

no, use buildtools/third_party/libc++, and buildtools/third_party/libc++abi

It may take a few more days to resolve the last dozen issues on Ubuntu 22.04. Once the modifications are complete, I will create PRs for the mediasoup-broadcaster-demo and libmediasoupclient repositories.

[janreyho]

@jmillani have some problems link mediasoup-broadcaster-demo on ubuntu2204.
And link test_mediasoupclient on ubuntu2204 has the same problem.

Thousands of std::__Cr:: related errors,probably due to compiler configuration issues, which have not yet been resolved.

I noticed that WebRTC m120 uses clang-18 for compilation on Ubuntu 22.04 (located in src/third_party).
Ubuntu 22.04 comes with default compilers gcc and g++. After installing Clang using sudo apt install clang, it provides clang-14.
I compiled clang-18 from the source repository and performed a make install.
However, when I use either clang-14 or clang-18 for linking, I encounter the same errors.
