  • FFMPEG Extra just codec information

    18 juin 2014, par Jim

    I am planning on using FFMPeg with Java, to detect a specific codec and convert this to another. Using the FFMpeg line -

        ffprobe -v quiet -print_format json -show_streams "input.avi"

    I can print off all of the stream information of the video, but this includes video information, audio information, all metadata, all tags and other information which I just don’t need.

    Question : Is it possible to launch an FFMpeg command which only returns the video codec, so I don’t have to wave through unnecessary information ?
