FFMPEG - Images to Video

Question

ffmpeg -f image2 -r 15 -i images/img%03d.jpg -vcodec libx264 video.mp4

I run this code with exec in php.

I am not getting the output. The video.mp4 is blank.

However if i modify this commade to something like this,

ffmpeg -f image2 -i i.jpg -vcodec libx264 -t 15 video.mp4

The video is running for 15 seconds.

I tried -r 1/15. It is not working too. Where do i do the mistake?

<?php
$command = "/usr/bin/ffmpeg -f image2 -r 15 -i images/img%03d.jpg -vcodec libx264 video.mp4";
exec($command);
?>

images folder has img001.jpg img002.jpg ... img005.jpg

Answer 1

Forcing the frame rate for both input (before -i) and output (before the output file name) only reliably works when you use raw input files, such as h.264 bitstreams, where you explicitly need to tell FFmpeg what frame rate you expect.

The actual option you should use for image2 is -framerate:

ffmpeg -framerate 25 -i thum-%04d.jpg -r 25 -c:v libx264 out1.mp4

Answer 2

try using

-loop 1

and

-r 1/4

and see what u get then
