Is that file existing in /tmp/jave/ folder?
Is it executable by the user which the server is running under?

Then you have to look at your server envrionemnt,
Perhaps some SELINUX settings or similar blocking the executable

i find that it fails in /tmp/ directory, but when i copied ffmpeg-amd54-3.2.0 to /data/ directory , it is executable.
So how do I specify the location where the ffmpeg file is generated or the location my program call when use ffmpeg in the system? I didn't do anything at the beginning, it was to automatically generate ffmpeg in /tmp/ directory

Jave uses the system temp location

https://github.com/a-schild/jave2/blob/master/jave-core/src/main/java/ws/schild/jave/process/ffmpeg/DefaultFFMPEGLocator.java

Line 57
File dirFolder = new File(System.getProperty("java.io.tmpdir"), "jave/");

So you can either set another temp location in the properties of the JVM, or implement you own ProcessLocator class, which point's to the location you desire.
If you wish to use a "static" ffmpeg version, you can put it in a known place and then implement the ProcessLocatorfor your environment
