ws.schild.jave.EncoderException: Exit code of ffmpeg encoding run is 137(Docker:linux)

[darwindu]

The Win10 environment is running normally;

Docker environment running Exception; Docker OS: Linux x86_64 x86_64 GNU/Linux Linux version 4.14.105-19-0008 (gcc version 4.8.2 20140120 (Red Hat 4.8.2-16) (GCC))

How to solve ？

The exit code 137 is returned by the underlying operating system, and there is nothing I can do from java to catch this. I can just report it as the cause, why the process did abort.

When you say that the OS (Docker) has 2GB of ram, then this is not the free ram, but overall ram of this instance. This memory is then shared by Docker/Java/ffmpeg and all other processes running in that instance.

Have you tried doubling ram?
