Eu decidi ganhar alguma experiência com a Bash e escrevi o script abaixo, que tem os seguintes recursos:
- Ele pode manipular todos os arquivos e pastas, colocados no diretório atual.
- Se houver mais de uma legenda ou arquivo de vídeo (exceto arquivos de amostra), o script solicitará a interação manual.
- Em todos os outros casos, o script moverá automaticamente todos os arquivos e pastas para um diretório de backup ( tenha cuidado para executá-lo! ), que será movido para o diretório pasta de lixo do usuário, em vez de ser excluída.
- Ele pode lidar com vários tipos de extensões de vídeo e legendas.
- Ele usa
mkvmergepara mesclar vídeo com arquivos de legenda e também usanotify-sendpara mostrar algumas mensagens na GUI. Também usagvfs-trashpara mover arquivos na pasta de lixo do usuário. - Ele pode ser usado como script do Nautilus ou como script de shell regular, mas o ambiente do GIU é obrigatório, enquanto o comando
notify-sendexiste no corpo do roteiro. - O nome do arquivo de saída pode ser baseado no nome do diretório (padrão) ou no nome do arquivo de vídeo de origem.
- Além disso, quando apenas dois arquivos são selecionados ( um arquivo de vídeo e um arquivo de legenda ), eles serão mesclados e o restante do conteúdo da pasta será retido . O arquivo de saída será nomeado após o arquivo de vídeo de origem. Esta opção está disponível somente quando o script é usado como script do Nautilus.
O script:
#!/bin/bash -e
# Check if all tools are available
[ -x /usr/bin/notify-send ] || (echo "Please, install 'notify-send'"; exit 1)
[ -x /usr/bin/mkvmerge ] || (echo "Please, install 'mkvmerge'"; exit 1)

Configuração:
-
Crie um arquivo executável e cole o conteúdo acima. Vamos chamar esse arquivo
merge-video-sub:touch merge-video-sub chmod +x merge-video-sub nano merge-video-sub -
Copie (ou
ln -s) este arquivo para a pasta~/.local/share/nautilus/scriptspara disponibilizá-lo como script do Nautilus para o usuário atual. -
No momento não consigo encontrar uma maneira de disponibilizá-lo para todo o sistema como script do Nautilus.
-
Copie o arquivo para
~/bin(e adicioneexport PATH=$PATH:~/binna parte inferior de~/.bashrc, se necessário) para disponibilizá-lo como comando shell para o usuário atual. -
Copie o arquivo em
/usr/local/binpara disponibilizá-lo como todo o sistema de comando do shell. -
O caminho curto é para
curldo script de meu PasteBin diretamente na pastanautilus/scripts:curl https://pastebin.com/raw/HrLTibuR | sed -e 's/\r$//' > $HOME/.local/share/nautilus/scripts/merge-video-sub chmod +x $HOME/.local/share/nautilus/scripts/merge-video-sub
