I'm using this code to run ffmpeg and return when it succeeded or failed using 2> & 1 and $var. The problem is that I would also like to generate a log.txt with the current ffmpeg process. I know it does using 2> log.txt but how do I use both options at the same time?
<?php
$ffmpeg = '"D:\FFMPEG\bin\ffmpeg.exe"' . " -loglevel verbose -n -i https://URLVIDEO -map p:0 -acodec copy -bsf:a aac_adtstoasc -vcodec copy video.mp4 2>&1";
exec($ffmpeg, $output, $var);
if($var){
echo 'error';
}else{
echo 'success';
}
?>
