I have

<?
echo shell_exec("ffmpeg -start_number 174 -i timelapse/20/%01d.jpg -vcodec libvpx -acodec libvorbis -r 24 timelapse/test.webm 2> timelapse/out.txt");
?>

I would like to create WebM video (timelapse) from the image of a webcam. Unfortunately I was unable to create a video in PHP5.

ffmpeg: unrecognized option '-start_number'

If I remove -start_numberI receive another error:

timelapse / 20 /% 01d.jpg: I / O error occured Usually That Means That input file is truncated and / or corrupted.

I saved as pictures 174.jpg 175.jpg .. and more.

On local PC is command OK, but if you run the command on the server, I get the error: ffmpeg: unrecognized option '-start_number' AND timelapse / 20 /% 01d.jpg: I / O error occured Usually That Means That input file is truncated and / or corrupted.

On the Internet I found even this command:

ffmpeg -i timelapse/20/{174..1204}.jpg -vcodec libvpx -acodec libvorbis -r 24 timelapse/test.webm

This statement was slightly better, but again with an error.
