Nesta página, mostramos como criar um projeto Google Cloud , ativar a
API Live Stream, criar
credenciais de autenticação e conceder
à sua conta uma ou mais
papéis do IAM. Esta página também mostra como
criar um bucket do Cloud Storage para armazenar os arquivos de saída da transmissão ao vivo e
como instalar um codificador para gerar streams de entrada que a API processa.

Sign in to your Google Cloud account. If you're new to
Google Cloud,
create an account to evaluate how our products perform in
real-world scenarios. New customers also get $300 in free credits to
run, test, and deploy workloads.
Para usar a API, você precisa de um codificador para gerar streams de entrada
que a API processe.
Instale o ffmpeg, já que esta página
explica como usar o ffmpeg para gerar streams de entrada. É possível instalar no
Cloud Shell usando o seguinte comando.

You can install this in Cloud Shell using the following command. \n\n sudo apt install ffmpeg"]]
