Changing the Tone Mapping Method?

[rmi_]

Thanks for your answer. 

The ffmpeg-log is in the original post, or do you need something else (I might have gotten the wrong one)? It says "[AVHWDeviceContext @ 0x55fca80a0480] Failed to get number of OpenCL platforms: -1001", that's why I was guessing that it's OpelCL related.
