Instead of cropping to mod4 what about padding to mod4 instead? But can this only be done when it really needs it, deinterlacing?
The issue with playing multiple videos with dxva2 is in fact a memory issue. I had process explorer set to show gpu system memory instead of gpu dedicated memory. On a 9800GTX 512MB dxva2 takes roughly 200 MB (SD) and 300 MB (HD) at 1680x1050 about half of that at 1024x768. Like system ram it seems to scale by memory capacity, on an intel 3000HD 64 MB dedicated, it takes about 20MB (SD) 30MB (HD) on 1366x768, about 2/3 of that on 1024x768. PS scalers use about half of what dxva2 does. Is there any way to control gpu ram in dxva2?
