  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • nohup >/dev/null alternative for windows

    24 décembre 2014, par Abdullah Al Mamun

    I’m running a php script which is not working properly in my windows OS but this is supposed to work in linux.

    I figured it out that nohup is not an associated tool with windows.

    $ffmpeg = 'C:\ffmpeg\bin\ffmpeg';
    
$command = "nohup >/dev/null 2>&1 ".$ffmpeg." -i {$input_path} {$ffmpeg_string} -stats -y {$output_path} 2> {$log_path} >/dev/null &";
    
exec( $command );

    So what could be my best alternatives if I want to run this code on windows.
    Detailed explanation will be greatly appreciated as I don’t know much about background process.

    nohup on windows, exec without waiting for finish

  • When downloading HLS video with FFMPEG it does not download the audio

    3 août 2021, par Thiago Franklin

    I have a problem, when I try to download an HLS video with FFMPEG, it downloads the video track, but it doesn't find the AUDIO. When running the HLS .m3u8 file in a player, it plays normally, audio and video, but when trying to download, it shows an error message saying that the audio cannot be found.

    


    I'm running the following command :

    


    ffmpeg.exe -i "https://teste-etv.espiritismo.tv/437602.m3u8" -codec:a libmp3lame -b:a 96k teste-hls.mp3

    


    Displays the following error when trying to download the audio :

  • how to use ffmpeg -cookies to download aes encrypted hls stream

    3 mars 2014, par Shuman

    i need this cookies, so i can download stream from a m3u8 file,(it has this line

    #EXT-X-KEY:METHOD=AES-128,URI="https://xxx/myStream.php?wowzasessionid=861683502"

    so i can get the key right ? ( i have the login credential cookies to that site )

    according to this discussion, it was there, and i checked the code on github, it has the option.

    but when i compile it with the default options, there is no cookies option. how do i turn it on ?
