Please don't be mad at me about that, but I have to come back to the iDCT comparison a few pages ago. I wanted to compare their speeds on my good old AMD Duron 800. And the interesting result was: No remarkable difference between all the 7 iDCTs.
Do you see my problem here?
Not yet?
Well... The Duron is not capable of SSE2 instructions, so iDCT=5 should have been crashing on my Duron - but it didn't crash. Therefore now I doubt that there are really different iDCT routines used at all! Or is there a "silent fallback" to a compatible iDCT in this case?
To show a different result: With CPU=6 it decoded (with a few filters) at 13.8 fps, with CPU=0 and fastMC=true at 19.4 fps. The d2v project file was made by DVD2AVI 1.76 (from an original TheWEF GKnot package) with MMX32 setting (iDCT=2), the test was running after a fresh install on Win2K with AviSynth 2.5.2 from the current GKnot 0.28.5 package.
