Answer 1

I just change the path of the destination of the image:

# path of image on the server
$image = '/users/xx/xxxx/sample/upload/image.jpg'; 

Then used the following:

# $ffmpeg - path of ffmpeg on the server
# $video_url - path of the video file on the server

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");  

Answer 2

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 guaratee 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.
