Eu tenho um único arquivo de vídeo VOB rodando 2h 20m com 50 episódios de um programa de TV. Não há marcadores de capítulo ou menu.
Posso usar uma ferramenta de linha de comando do Linux para detectar a tela preta entre cada episódio e criar um arquivo MP4 de cada episódio de 5 minutos?
Aqui está a saída de 'mediainfo' ...
