anyone good with ffmpeg?

I've been using this cmd to generate thumbnails automatically for videos my employer uploads.

$ffmpeg -i $movie1 -deinterlace -an -ss $second -t 00:00:01 -r 1 -y -vcodec mjpeg -s $size -f mjpeg $thumb 2>&1

 

It has been working great until we recently switched all our videos over the H264 at which point it now fails.

 

I've tried switching the -vcodec and -f flags to libx264 and various combinations with mjpeg with no luck.

 

Here is one cmd:

$ffmpeg -i $video -deinterlace -an -ss 5 -t 00:00:01 -r 1 -y -vcodec libx264 -vpre default -f mjpeg -s $size $thumb 2>&1

I spent ages looking for this, so when i found it i had to share it on the web. It works !!! ( took me 2 days) Warning this only works if you already have the ffmpeg libary already installed ( my host did)

 

$extension = "ffmpeg";

$extension_soname = $extension . "." . PHP_SHLIB_SUFFIX;

$extension_fullname = PHP_EXTENSION_DIR . "/" . $extension_soname;

 

// load extension

if(!extension_loaded($extension)) {

    dl($extension_soname) or die("Can't load extension $extension_fullname\n");

}

 

  $exec_string = 'ffmpeg -i /home/parkhall/public_html/bands/design/uploads/001Spin.mp3 /home/parkhall/public_html/bands/design/uploads/omfg.mp3';

  exec($exec_string);
