Capture FFMPEG output

Question

I need to read the output from ffmpeg in order to even try the solution to my question from yesterday. This is a separate issue from my problem there, so I made a new quest

Answer 1

To get output status and output:

exec("ffmpeg -i input.avi output.mp4 2>&1", $output, $returnStatus);

print_r($output);

if($returnStatus === 0){
   // success
}
else {
   //fail
}
