Video: Error in video decoding on either Linux or AVX512 CPU (ffmpeg alignment issue?)

@Sean-Devonport curiously I do see this, but only on 4.3, and only on non-AVX512 CPU. Maybe the "problematic" instances you get happen to (somehow) have AVX 512 disabled?

@Sean-Devonport interesting :( Which version exactly do you see this issue now with, and are the rendering artifacts the same, or do they look different?

VSE proxies build slower than it could be

@AntonB I think it should be faster than before, yes. Why your task manager does not show close to 100% CPU load, I don't know. I suspect it might be something to do with your CPU being this…

Major part of this (lack of multi-threading in proxy resolution downscaling) was addressed by #128054. There are other possible performance improvements, but we'll tackle them separately.

VSE: Multi-threaded video proxy downscaling

Overall there is definitely improvement, but I would like to reproduce 100% CPU usage :) Can you share your sample, so I can cross check?

VSE proxies build slower than it could be

@AntonB if you try current 4.3 daily builds, then proxy building is already faster compared to 4.2.1 on Windows (ffmpeg has been taught to properly use CPU SIMD instructions; this was a windows-onl…
