Como recuperar informações de arquivos de vídeo da linha de comando no Linux?

Question

Eu gostaria de ver na linha de comando todas as informações pertencentes a um determinado arquivo de vídeo, incluindo comprimento, qualidade, taxa de bits, resolução, formatos de áudio e vídeo, número e idioma de áudio e legendas, e assim por diante; mais, o melhor.

Tanto quanto agora eu devo recorrer na aba "information" do VLC, porque mesmo o gerenciador de arquivos Dolphin não está me ajudando com isso: ele mostra apenas algumas dessas informações e apenas alguns formatos (por exemplo, .mkv doesn parece ser suportado dessa forma).

    

Answer 1

Dê uma mediainfo uma tentativa. Na linha de comando, digite mediainfo input.mkv . Para informações mais detalhadas sobre o vídeo mediainfo --fullscan input.mkv .

Em distribuições recentes do Linux, você também pode obter informações usando avconv :

$ avconv -i ch1_video_01.mpg

Answer 5

O Mediainfo é uma ótima ferramenta. Como alternativa, você pode pegar os detalhes usando ffprobe também.

$ 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
