Bagaimana cara mengambil informasi file video dari baris perintah di Linux?

Saya ingin melihat dari baris perintah semua informasi yang berkaitan dengan file video yang diberikan, termasuk panjang, kualitas, bitrate, resolusi, format audio dan video, jumlah dan bahasa stream audio dan terjemahan, dan sebagainya; lebih banyak, lebih baik.

Sejauh ini saya harus menggunakan tab "informasi" dari VLC karena bahkan pengelola file Dolphin tidak membantu saya dengan ini: ini hanya menunjukkan kepada saya beberapa informasi ini dan hanya untuk beberapa format (yaitu .mkvsepertinya tidak didukung seperti itu) ).

Berikan MediaInfo mencoba. Pada tipe baris perintah mediainfo input.mkv. Untuk informasi video yang lebih rinci mediainfo --fullscan input.mkv.

Seperti yang ditulis Günay Gültekin, Anda hanya bisa mendapatkan atribut tertentu, tetapi kutipannya tidak ada:

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

Berdasarkan ini, saya menulis pembungkus kecil untuk menghitung durasi file yang ditemukan dengan output ringkasan:

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

Pada distribusi linux terbaru Anda juga bisa mendapatkan informasi menggunakan avconv:

$ avconv -i ch1_video_01.mpg
