    Checklist:
    - You have ffmpeg installed
    - Image file is located in same folder as your php script

    Are you running this on cgi or cli?

    Assuming your frame rate is 29.97. You can try
    
ffmpeg -y -i VIDEO_NAME -ss 10 -vframes 1 -an -f mjpeg -sameq IMAGE_NAME
ffmpeg -y -i VIDEO_NAME -ss 40 -vframes 1 -an -f mjpeg -sameq IMAGE_NAME
    Code (markup):

    Maybe I don't doing something write. I did:
    But I got videoimage000000.jpg to videoimage000022.jpg

    I don't know I would like to put two images in one folder and to make video from this two images, which first will be first 10 sec of video and second image next 40 sec. of same video.
    Thanks

    exec("/usr/bin/ffmpeg -y -i $flvfile -pix_fmt rgb24 -vframes 1 -ss 00:00:10 -an -vcodec mjpeg -f rawvideo -s 128x110 $thumb");
    exec("/usr/bin/ffmpeg -y -i $flvfile -pix_fmt rgb24 -vframes 1 -ss 00:00:40 -an -vcodec mjpeg -f rawvideo -s 128x110 $thumb");

    replace 00:00:08 with a $var or a different time than needed, obviously that is at 10 seconds
    $thumb being the filename of the thumb to create $flvfile being the path to the flv file

    I guess you're close just have a time format that not working? or perhaps you might be using a file that is using/encoded with DRM, which in case you can't get thumbs from it... check that
