This is my code using ffmpeg
I want to have video thumbnail but I'm not familiar in ffmpeg
can someone know the error I got.

Also This is my code:
$video_url ='https://URL/upload/4b8acab123563649f19e07450d810df6.mp4';
$ffmpeg = '/opt/local/bin/ffmpeg';
$image = 'image.jpg';
$interval = 5;
$size = '320x240';
shell_exec($tmp = "$ffmpeg -i $video_url -deinterlace -an -ss $interval -f mjpeg -t 1 -r 1 -y -s $size $image 2>&1");
According to ffmpeg forum this can be ignored when called from the command line and I always ignored it. One thing you can try (test with a dummy file PLEASE) is to add -pix_fmt yuvj422p
to your last line so it look like this:
shell_exec($tmp = "$ffmpeg -i $video_url -pix_fmt yuvj422p -deinterlace -an -ss $interval -f mjpeg -t 1 -r 1 -y -s $size $image 2>&1");
As I said, test it please as I cannot guarantee the results but as far as I'm concerned I've used ffmpeg thousand of times and everything looks just fine even with the warning.

Afaict, the warning is primarily meant for library users, ffmpeg users should not be affected.
OK, will just ignore it then.
