Description:

/var/www/ad-1/www/uploads/ad/v/5e/8f/98/88/5e8f98881c4da88fb31a1fe1b93c45d6.mp4
-y -f mjpeg -ss 3 -t 0.001 -s 640x1136
/var/www/ad-1/www/uploads/ad/v/5e/8f/98/88/5e8f98881c4da88fb31a1fe1b93c45d6.jpg")
in php file, it doesn't work. But I use `exec("whoami")`, it work well.
When I use
fmpeg -i
/var/www/ad-1/www/uploads/ad/v/5e/8f/98/88/5e8f98881c4da88fb31a1fe1b93c45d6.mp4
-y -f mjpeg -ss 3 -t 0.001 -s 640x1136
/var/www/ad-1/www/uploads/ad/v/5e/8f/98/88/5e8f98881c4da88fb31a1fe1b93c45d6.jpg
in command line it work well. But when I use
exec("`fmpeg -i
/var/www/ad-1/www/uploads/ad/v/5e/8f/98/88/5e8f98881c4da88fb31a1fe1b93c45d6.mp4
-y -f mjpeg -ss 3 -t 0.001 -s 640x1136
/var/www/ad-1/www/uploads/ad/v/5e/8f/98/88/5e8f98881c4da88fb31a1fe1b93c45d6.jpg")
in php it doesn't work.
Test script:
---------------
exec("fmpeg -i
/var/www/ad-1/www/uploads/ad/v/5e/8f/98/88/5e8f98881c4da88fb31a1fe1b93c45d6.mp4
-y -f mjpeg -ss 3 -t 0.001 -s 640x1136
/var/www/ad-1/www/uploads/ad/v/5e/8f/98/88/5e8f98881c4da88fb31a1fe1b93c45d6.jpg")
