  • Le plugin : Podcasts.

    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux

  • PHP ffmpeg conversion error

    6 mars 2016, par Enn Fenn

    I tried to convert some videos with ffmpeg and PHP.

    When I execute the following command in PHP exec()

    /usr/local/bin/ffmpeg -i /home/test/public_html/test.m4v -vcodec libx264 -acodec libmp3lame -r 30 -s 640x480 -b 100k /home/test/public_html/output_640x480_test.m4v

    The same conversion is working fine in another server. But not in our current server. What should I do to get rid of this error ?
