  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Presenting more then 2 videos using FFmpeg

    9 décembre 2012, par Radagskar

    i found this answer for combining 2 videos using Ffmpeg

    ffmpeg.exe -i LeftInput.mp4 -vf "[in] scale=iw/2:ih/2, pad=2*iw:ih [left]; 
    
    movie=RightInput.mp4, scale=iw/3:ih/3, fade=out:300:30:alpha=1 [right]; 
    
    [left][right] overlay=main_w/2:0 [out]" -b:v 768k Output.mp4

    Is there a way to combine more then 2 ? i tried adding [bottom] and [upper] but i'm failing to understand how the overlay works and where do i put more videos.
    Thanks

  • ffplay with cookies

    4 décembre 2014, par Steven Penny

    Normally with ffplay you can play a video like this

    ffplay http://easy.com/foo.flv

    However I have come across a video that requires a cookie. wget has no trouble with this

    wget http://hard.com/foo.flv --load-cookies cookies.txt

    Can ffplay play a video that requires a cookie ?

    Based on pogorskiy’s answer this works

    ffplay -headers $'Cookie: sbsession=sbg&sbuser=lorem\r\n' http://hard.com/foo.flv

  • PHP shell_exec wait for script to done ? [duplicate]

    6 mars 2016, par Melih Büyükbayram

    This question already has an answer here :

    I have a PHP script that queries a database for a list of jobs to be done and fires off other PHP scripts based on what it finds in the database (basically a process queue).

    Some of the scripts that the queue runner script executes may take 30 seconds or so to finish running (convert video, resizing images, etc).

    The problem is that shell_exec() in the queue runner script calls the processing scripts, but then doesn’t wait for them to finish, resulting in the queue not being completed.

    Queue runner script :

    #!/usr/bin/php
    
<?php
    
    // Loop through database and find jobs to be done
    
    shell_exec("nohup $command > /dev/null 2> /dev/null & echo $! &");
    
?>

    Running the job script directly from the command line works and the PDF is created.

    Any ideas on how to fix this ? Or a better way to run a process queue ?
