Linuxでコマンドラインから動画ファイルの情報を取得する方法は?

command-line linux video

長さ、品質、ビットレート、解像度、オーディオとビデオのフォーマット、オーディオストリームと字幕の数と言語など、与えられたビデオファイルに関連するすべての情報をコマンドラインから見たいと思います

今のところ、Dolphin のファイルマネージャでさえ、これらの情報の一部しか表示されないし、一部のフォーマットしか表示されないので、VLC の “情報” タブに頼らざるを得ません

mediainfo を試してみてください。コマンドラインで mediainfo input.mkv と入力してください。より詳細な動画情報については、mediainfo --fullscan input.mkvと入力してください

Mediainfo は素晴らしいツールです。代わりに ffprobe を使って詳細を取得することもできます

$ 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

Günay Gültekinさんが書いているように、特定の属性しか手に入らないのですが、引用が抜けていました

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

これに基づいて、私は要約を出力することで、見つかったファイルの持続時間を計算するための小さなラッパーを書きました

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