  • FFMPEG extract h264 video (can't see video)

    28 décembre 2015, par Marco Ronchi

    I’m trying to extract a portion of video from another video with FFMPEG. I use this command line :

    ffmpeg -i C:\Temp\test.avi -ss 00:00:30.0 -c copy -t 00:00:10.0 C:\Temp\out.avi

    and this is the output messages :

  • Can FFmpeg perform audio phase subtraction ? [closed]

    22 avril 2023, par Calarpo

    I can do audio phase subtraction in Adobe Audition like so : https://www.youtube.com/watch?v=vNvJKBg3yds

    


    How can I do this with FFmpeg ? Is it possible ?

    


    I've googled for audio phase subtraction, and looked at https://ffmpeg.org/ffmpeg-filters.html, nothing seems to work for me.

    


    I want to do phase subtraction in batches and support for stereo audio.
