  • Keeping control of your media in your hands

    13 avril 2011, par

    The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.

  • ffplay -noborder option missing argument

    10 janvier 2021, par Tomás Arturo Herrera Castro

    If I do :

    


    ffplay -i vid.mp4


    


    ffplay works fine, however if I try the borderless option :

    


    ffplay -noborder -i vid.mp4

Failed to set value '-i' for option 'noborder': Option not found


    


    Trying the -noborder option at the end of the command :

    


    ffplay -i vid.mp4 -noborder

Missing argument for option 'noborder'


    


    Any clue on the argument -noborder is waiting for or why isn't this working ?

    


    This is the ffplay version I am using :

  • ffmpeg converting mp4 to gif with color palette results in truncated video

    6 décembre 2019, par Tik0

    I want to generate a gif from my mp4 movie with ffmpeg (ffmpeg version 2.8.15-0ubuntu0.16.04.1) using a color palette. Everything works fine if I do not use a palette :

    $ ffmpeg -i in.mp4 -filter_complex "scale=160:-1" out.gif
    ...
    frame= 2003 fps=251 q=-0.0 Lsize=   21172kB time=00:01:20.12 bitrate=2164.7kbits/s    
    video:21155kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.077667%

    But using a palette like so results in Buffer queue overflow, dropping messages and a truncated video

    $ ffmpeg -i in.mp4 -filter_complex "[0:v] scale=160:-1, split [a][b];[a] palettegen [p];[b][p] paletteuse" out.gif
    ....
    [Parsed_paletteuse_3 @ 0xc56de0] [framesync @ 0xd1af08] Buffer queue overflow, dropping.
