hi,

G-Knot 0.27 talks about "in options you can enter a name for an alternative mpeg2dec.dll"

But which are alternative mpeg2dec.dll plugins and what are their advantages / disadvantages?

how about using the search button? All you need to do is enter mpeg2dec.dll, you'll get a list of results, first hit being this thread, 3rd thread being http://forum.doom9.org/showthread.php?s=&threadid=32136&highlight=mpeg2dec.dll. In that thread you'll see why it can make sense using an alternative version.

Hi-

I use MPEG2DEC2.dll and MPEG2DEC3.dll a lot because of P4-SSE2 optimizations (but as near as I can tell, they speed encoding by less than 2% when compared to the regular MPEG2DEC.dll). MPEG2DEC3 is also useful because of some built in pre-processing. But be careful if you IVTC, because the pre-processing (if you turn it on) can screw it up. Also, you can't use MPEG2DEC3.dll when running the Compress Test as there's no SelectRangeEvery(xxx,xxx) built into it. So I wind up switching around a lot.

Doom9-thanks for keeping an eye on things in TheWEF's absence.

I don't seem to have a problem with that function (SelectRangeEvery). I'm using that DLL & Avisynth 2.5. There was a time some weeks ago when that function wouldn't work, but I think it was fixed in either a recent update of Avisynth 2.5 or mpeg2dec3.dll.

Hi-

Yes, I was referring to AviSynth 2.07 and YUY2 (unless MPEG2DEC3 has had that command included now-maybe I should look around).

Edit: Nope, I have the latest for AviSynth 2.07. Can't run the Compress Test with it. As you said, it's the newer one for AviSynth 2.5 that has it included.

No, like you said it's not included.

No it hasn't, it's an internal filter of AviSynth v2.5.

OK-Thanks Wilbert.
