Question

I have an exec function in php file that execs a bash script. It script calls fmpeg to transcode a video file.

How can I know when transcoding is finish??

$script = "/opt/lamp../name.sh"
exec("$script $videoIn $id")

I will try using next code but it doesn’t workd.

if (exec("$script $videoIn $id"))
{
//print on screen that the video has been transcoded
}

Answer 1

The function exec() will return when the executed command is finished. My guess is that the command fails somehow (possibly because you’re not using escapeshellcmd() and escapeshellarg()).
