    The above command not work, because drawbox do not support ’t’, so i tried another one

  • Webm video playing video & audio in Movies & TV app but will only play video in windows media player and html ?

    24 décembre 2019, par Kate LeVering

    I have created a webm video file with transparency with ffmpeg out of a series of png files. Then I add the audio track again in ffmpeg (I have tried both the opus and vorbis codecs). When I play it in the Movies & TV app it plays just fine (audio and video). In windows media player only the video plays. In html (inside a video tag) the video will play if it is set to ’muted’ but if it is not muted it doesn’t play.

    I am not sure what is going on. Does anyone have any insights. Do I need to run the audio from a seperate file ?

    Thanks, Kate

  • Ffmpeg : Output a video made of several video chunks of the input video

    20 mai 2013, par mad

    I was wondering if it was possible to output a video made of several extracts of the input video.
    For example outputting a video made of the first 10s of each minute of the input.

    I know you can do it programmatically, calling several time ffmpeg with -ss and -t to make the chunks and then merge them, but is it possible to do it in one command using video filters ?

    Thanks !
