I want to export all frames from a lot of video files, automatically in a jenkins build job using ffmpeg.

This script is running fine when I ssh into the slave and execute it in the same folder:

find . -name "*.mp4" -exec ffmpeg -i {} -qscale:v 1 -vf fps=6 {}_exportedFrame_%d.jpg \;

It should find all mp4 files and run ffmpeg on them.

It fails with this message when jenkins is running it (execute shell plugin):

08:51:32 find: ffmpeg: No such file or directory
08:51:32 find: ffmpeg: No such file or directory
08:51:32 find: ffmpeg: No such file or directory
08:51:32 find: ffmpeg: No such file or directory
...many more lines of the same error

Output from terminal (it's running fine):

bash-3.2$ find . -name "*.mp4" -exec ffmpeg -i {} -qscale:v 1 -vf fps=6 {}_exportedFrame_%d.jpg \;

Build slave is running the latest version of mac os. ffmpeg is installed.

edit: I've added ffmpeg to the paths file

bash-3.2$ cat /etc/paths
bash-3.2$ type ffmpeg
ffmpeg is /usr/local/bin/ffmpeg

I'm still getting the same error.


Probably ffmpeg is not in the PATH of the jenkins job.

Run type ffmpeg in your terminal to see where ffmpeg is located and echo $PATH in your jenkins job and compare.

  • I've added ffmpeg to paths, it still fails with the same error. See my edit in the question. – Tamás Jan 22 at 14:15
  • And what does echo $PATH print when you add it to your jenkins job script? – Bodo Jan 22 at 14:19
  • I guess adding ffmpeg to /etc/paths did not help. Output of echo $PATH: /usr/bin:/bin:/usr/sbin:/sbin – Tamás Jan 22 at 14:21
  • I don't know when /etc/paths is used to construct the PATH variable. Maybe you have to restart jenkins. – Bodo Jan 22 at 14:31
  • Yeah jenkins was the problem, I'm using now the explicit path (/usr/local/bin/ffmpeg) to ffmpeg in my scripts instead, and it works. It's lame, but changing the path variable did not work somehow. I guess some plugin or some setting somewhere overwrites my jenkins slave environment settings. – Tamás Jan 23 at 13:13
