hi i want to include the vedio download option in my webpage. I am using ffmpeg, but it seems to work very slow. Is there is any other way to do this or how to spead up the ffmpeg. i am using this code to get the frames from the vedio.

vedio dönüştürmek

$call="ffmpeg -i ".$_SESSION['video_to_convert']." -vcodec libvpx  -r 30 -b ".$quality." -acodec libvorbis -ab 128000   -ar ".$audio." -ac 2 -s ".$size." ".$converted_vids.$name.".".$type." -y 2> log/".$name.".txt";
$convert = (popen("start /b ".$call, "r"));
pclose($convert);

vedio gelen çerçeveyi almak için

exec("ffmpeg -vframes 1 -ss ".$time_in_seconds." -i $converted_vids video_images.jpg -y 2>); 

ama bu kod sürekli herhangi bir hata, yükleme üretmez.
