SSIM with Opencl? - Werve - 03.12.2020
I don't know if this is a bug or a hardware limitation, but if I encode with x264 and enable OpenCL (x264-Misc) and SSIM metrics, it doesn't appear in the report file.

Hybrid properly sets the command line, the encoder even warns tha tthe results will be invalid since ssim&psy are used:
x264 [warning]: --ssim used with psy on: results will be invalid!Cu Selur

It uses ffmpeg to calculate it?
The command described here seems to work https://stackoverflow.com/questions/17707153/how-to-use-ssim-in-ffmpeg (I have ffmpeg 4.3.1)
For different bugs is better to open a thread for each one or continue the same one?

Quote:It uses ffmpeg to calculate it?No, Hybrid does not use ffmpeg to calculate anything.
The ffmpeg command you link to only works if ffmpeg is used for the encoding which it isn't.
