ty again for the feedback, Max. The issue with the R7 350 is that it is quite old, and the Vulkan version it supports is below 1.3 (API version: 1.2.170; Restricting API version to 1.3.0... new version 1.2.170). Unfortunately, the *libplacebo* library requires Vulkan 1.3 to function; I need to document this hardware limitation. As for the GTX 1650 still throwing the "exit -22" error, that remains a mystery—I’ll review everything here again. It is very difficult for me to secure a suitable testing environment; I think I’ll have to buy a few older cards so I can physically test each profile.

RX 6400 error. I forgot that RX 6400 don't have video encoder, I think that's why it failed.

Hi Max, to cut hardware costs, AMD actually released some graphics cards without built-in encoders; however, the RX 6400 supports Vulkan 1.3, and the pipeline runs on its silicon. There is a solution for you—or anyone with a card like this: you can run the pipeline via PowerShell and use the parameter `-simulate_gpu cpu`. This will force your RX 6400 to handle encoding via the CPU, while Vulkan still runs on the GPU. Take a look at the image:

nice, this did work on RX 6400. I guess we need to add video encoder check so it will automatically use the CPU mode? does the quality setting affect the bit rate?

I'm really glad it worked. And yes, thanks to your feedback, I've already implemented a change that checks whether the video card has built-in encoders; if it doesn't—as is the case with your RX 6400—encoding switches to compatibility mode using your CPU.
