Apparently, you use a differently built ffmpeg in the script.

Though your ffmpeg's configure command line told it to build with
libx264, that apparently didn't work, and this ffmpeg doesn't support
libx264. (You can double-check with "ffmpeg -encoders".)

Can you not use the same ffmpeg as you use "on the command line" for
your script?

Otherwise, you need to rebuild that ffmpeg which is called from the
script in presence of the "libx264-devel" package, or you need to build
libx264 yourself beforehand, and make sure it is found while
configuring, see this section of the RedHat compilation guide:
https://trac.ffmpeg.org/wiki/CompilationGuide/Centos#libx264

Hope this helps,
