Comment:

 I discovered, that this error seems to be a run into architecture
 limitations, when I use libx265 without pool and frame limitations. I
 cannot really ensure this because I am still not able to reproduce the
 error consistently.

 Since I limited "pools" and "frames" I am able to run multiple conversions
 in parallel to be able to use 100% CPU on a modern processor with 16/32
 cores/threads.

 I assume it's a stack pointer overflow.

 Problem is now solved for me!
