Running on MacOS

To develop using your mac, make sure you have ffmpeg@5 installed:

brew install ffmpeg@5

You can have multiple versions of ffmpeg installed in your mac. To find where the specific `ffmpeg@5`` was installed, run:

sudo find /opt/homebrew -name avcodec.h

Let's assume the prior command showed two entries:

sudo find /opt/homebrew -name avcodec.h
/opt/homebrew/Cellar/ffmpeg/7.0_1/include/libavcodec/avcodec.h
/opt/homebrew/Cellar/ffmpeg@5/5.1.4_6/include/libavcodec/avcodec.h

You must configure the CGO library path pointing it to the ffmpeg 5 folder.

export CGO_LDFLAGS="-L/opt/homebrew/Cellar/ffmpeg@5/5.1.4_6/lib/"
export CGO_CFLAGS="-I/opt/homebrew/Cellar/ffmpeg@5/5.1.4_6/include/"
export PKG_CONFIG_PATH="/opt/homebrew/Cellar/ffmpeg@5/5.1.4_6/lib/pkgconfig"

Now, you can run it locally:

go run main.go -- --enable-ice-mux=true
go test -v ./...
