// Fetch informations from DB about one file to process
// and mark it as "processing"
// Those would be fetched / determined from the data you just fetched from DB
$in_file = 'in-file.avi';
$out_file = 'out-file.avi';
// Launch the ffmpeg processing command (will probably require more options ^^ )
// The PHP script will wait until it's finished :
// No background work
// No need for any kind of polling
$output = shell_exec('ffmpeg ' . escapeshellarg($in_file) . ' ' . escapeshellarg($out_file));
// File has been processed
// Store the "output name" to DB
// Mark the record in DB as "processed"
