Eu corri ffserver -d -f /etc/ffserver.conf e está sendo executado.
Agora eu quero pegar um arquivo de vídeo e transmiti-lo para este servidor.
Eu corri no mesmo computador:

e tem uma qualidade muito ruim. Resolução muito baixa, muitas vezes interrompe e congela.
É possível obter qualidade do YouTube?
