Opera: Como Instar Codec H.264 para Executar Vídeos?

Por padrão, o Chromium não oferece suporte a codecs proprietários (como h.264, aac). Informações oficiais: https://www.chromium.org/audio-video.

Mas podemos instalar o codec de algumas formas para que vídeos em navegadores de internet não deixem de ser executados.

Baixe Script do GitHub

obs.: posto abaixo o texto para não precisar visitar o link.

1. Acesse esse link do github: https://gist.github.com
2. Copie as linhas do script e cole em um arquivo qualquer de texto.
3. Clique com o direito no arquivo salvo e vá em propriedades. Dê permissão de execução. Ou, como alternativa, abra o terminal e execute o seguinte comando, iremos supor que o arquivo se chama h264_codec_opera.sh, execute: chmod +x h264_codec_opera.sh
4. execute o arquivo no terminal da seguinte forma: sudo ./h264_codec_opera.sh

# -o       Write output to  instead of stdout.
#
# -s             Silent or quiet mode. Don't show progress meter or error messages.
#
# -w     Make curl display information on stdout after a completed transfer. The format is
#                a string that may contain plain text mixed with any number of variables.
