¿Cómo recuperar la información de un archivo de vídeo desde la línea de comandos en Linux?

Me gustaría ver desde la línea de comandos toda la información relativa a un archivo de vídeo determinado, incluyendo la duración, la calidad, la tasa de bits, la resolución, los formatos de audio y vídeo, el número y el idioma de los flujos de audio y subtítulos, etc.; cuanto más, mejor.

Ahora mismo tengo que recurrir a la pestaña de “información” de VLC porque ni siquiera el gestor de archivos Dolphin me ayuda con esto: sólo me muestra algunas de estas informaciones y sólo para algunos formatos (por ejemplo, el .mkv no parece estar soportado así).

Pruebe con mediainfo . En la línea de comandos escriba mediainfo input.mkv. Para obtener información de vídeo más detallada mediainfo --fullscan input.mkv.

Ejemplo de salida:

Como escribió Günay Gültekin, sólo se puede obtener un atributo específico, pero faltaban las comillas:

mediaInfo --Output='Video;%Duration%' filename.mp4

Basado en esto, escribí un pequeño wrapper para calcular la duración de los archivos encontrados que emite un resumen:

echo "scale=2; ($(find /foo/bar -type f -exec mediainfo --Output='Video;%Duration%+' {} \; | grep -v ^$ | tr -d \n)0)"/60000/60|bc

Mediainfo es una gran herramienta. Como alternativa puedes obtener los detalles usando ffprobe también.

$ ffprobe -hide_banner -loglevel fatal -show_error -show_format -show_streams -show_programs -show_chapters -show_private_data -print_format json /home/sathish/Videos/Aandipatti.mp4
