  • FFMPEG execution from PHP

    13 juin 2014, par egekhter

    I’m trying to execute FFMPEG from a PHP script and could not figure out the best practice for doing so when running a background process - do we use shell_exec, exec, passthru, proc_open...?

    On https://trac.ffmpeg.org/wiki/Using%20FFmpeg%20from%20PHP%20scripts, they use an example of

    echo shell_exec("ffmpeg -y -i input.avi output.avi null >/dev/null 2>/var/log/ffmpeg.log &");

    In my code I was initially using :

    exec($cmd." 2>&1", $out, $ret);

    But then switched to :

    passthru($cmd." 2>&1", $ret);

    I chose passthru because I could actually see the encoding process in terminal, but now it’s a moot point since I’m running multiple background processes. Which is the recommended function for running background processes ?

  • avconv/ffmpeg command to encode nice full hd webm for chrome

    18 mars 2016, par xavier.seignard

    People from the artistic direction gave me big .mov and .mp4 that I need to put on a web app, but so far they are so huge that decoding/rendering is kinda bad on chrome (this is a chrome only experience since it will run on electron at the end).

    I’d like to re-encode them in .webm since it seems to have the best support in chrome.

    But I’m kinda lost on how to re-encode them without significative visual quality lost.

    For now I use (taken from https://trac.ffmpeg.org/wiki/Encode/VP8)

    ffmpeg -i myVid.mp4 -c:v libvpx -crf 8 -b:v 2M -c:a libvorbis myVid.webm

    So, does anyone have a nice avconv/ffmpeg command that will produce nice and easy to render .webm ?

    Regards.
