QUICK START

Make sure you have the ffmpeg 5.x.x. You must configure the CGO library path pointing it to ffmpeg 5.

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 install and run it:

go install github.com/flavioribeiro/donut@latest
donut

Here are specific instructions to run on MacOS.

RUN USING DOCKER-COMPOSE

Alternatively, you can use docker-compose to simulate an SRT live transmission and run the donut effortless.

make run

OPEN THE WEB UI

Open http://localhost:8080/demo. You will see two text fields. Fill them with the your streaming info and hit connect.
