Mediasoup server with CMake

tomkwok/mediasoup-cpp is a fork of barry-ran/mediasoup-cpp, which is a fork of versatica/mediasoup to switch build system from node-gyp to cmake. This would be ideal for compiling on a single-board computer such as Raspberry Pi, but I found that some work is needed to complete the set-up.

This fork of mine brings the following changes:

• Fixed building on Linux and macOS: PATH_MAX constant, case-sensitive header file name, -std=c++14 in CMAKE_CXX_FLAGS for use of std::initializer_list
• Added detailed documentation for building and usage in README.md
• Updated dependency OpenSSL version
• Backport commits from upstream versatica/mediasoup
• (Todo) Re-write remaining Node.js components in C++ including Transport
• (Todo) Add parsing of command line arguments to demo executable and pass them to workers spawned
• (Todo) Move dependencies in deps/ to git submodules for more convenient updates from upstream

Building

Configure the number of processes for make as suitable to speed up compilation.

mkdir -p build/
cd build/
cmake ..
make -j3

Usage

After building, a binary named mediasoup-worker can be found in directory build/. The worker binary may be used with a demo server implemented with mediasoup-go with the environment variable MEDIASOUP_WORKER_BIN set to the path of compiled mediasoup-worker. Hence, we avoided having to use a Node.js build system to compile the worker written in C++, and also avoided having to use the Node.js implementation of the endpoint server.

A binary named mediasoup-demo also found in directory build/ is useful for debugging only as it cannot be used to launch a server instance for the demo application. The endpoint server re-write in C++ found in barry-ran/mediasoup-cpp is incomplete.

Web app

The demo web app can be found in mediasoup-demo in directory app/. It can be built using Node.js with the following commands in directory app/.

npm install
gulp dist

The built web app found in server/public/ can then be taken out and hosted on other machines such as a Raspberry Pi with any web server such as nginx. Note that leading / can be removed from paths in index.html if the web app is not hosted at root /.
