Wie kann man unter Linux Videodatei-Informationen von der Kommandozeile abrufen?

Probieren Sie mediainfo aus. Geben Sie in der Befehlszeile mediainfo input.mkv ein. Für detailliertere Videoinformationen mediainfo --fullscan input.mkv.

Wie Günay Gültekin schrieb, kann man nur ein bestimmtes Attribut erhalten, aber die Anführungszeichen fehlten:

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

Basierend darauf habe ich einen kleinen Wrapper geschrieben, der die Dauer der gefundenen Dateien berechnet und eine Zusammenfassung ausgibt:

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

Mediainfo ist ein großartiges Werkzeug. Alternativ können Sie die Details auch mit ffprobe auslesen.

$ 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
