Dvd2avi beta testers needed

Hi all,

I'm finally back, I'm on holidays and I can work again on Dvd2avi (there's not enought holidays in a year ).

Last time, my release of Dvd2avi has problem with P4 system, I think I solved the pb but I need some testing (my brother has a P4 but he just began to work in Dusseldorf so I can't test).

I also added Tom's SimpleResize (@Tom I just love the way you comment your code : it's clear and funny sometimes). It seems to work well. Currently only destination horizontal size is checked (multiple of 4) but clip size is not checked (IIRC horizontal size must a multiple of 4 or 8 ????) and I haven't added all the gui things to allow interlaced or warped resize. But the speed increase is here.

So if you want to test it or to look at the code (it's a little bit messy for the moment) PM me or give me your email through this topic. As soon as my P4 code work (fast ) I will commit at least my optimized motion compensation code on CVS.

Happy to be here again.

Hi Vlad -

I guess I'm willing to try it (P4) just because you liked my jokes (I hope they were jokes )

Let me know what to get & try.

PS - I really really do promise to remove some of those SimpleResize x*4 limitations one of these days. I just never seem to get around to it.

I have a 1.60ghz northwood, if you still need testers.

Source or binary is fine by me.

EDIT: Postcount 1... I must have posted before? I could swear I did... why would I sign up so long ago and never post? Well, whatever.

Hi vlad59,

I've tested your program and it crashes when I hit F5 (to preview).

I'm using WinXP Pro on P4 1.60A GHz.

Hope you find the bug and good luck!

Just send me e-mail when you fix it.

I've the same problem.
If i decide to save the project, using idtc="64bit sse2 mmx", clip&resize="2.35:1".
it took me 21min to a 2hours10min movie to create a .d2v file

but the main problem is that I can't display the movie through an .avs file generate by gordian knot. I can only see a gray screen...

If you save a project specifying either P4 SSE2 or clipping parms then you will probably need a version of MPEG2DEC.dll that supports these.

Try www.trbarry.com/MPEG2DEC2.zip

The P4 IDCT & cropping is supported but the resize will still be ignored by MPEG2DEC2.dll.

It's working...

@ vlad59:

Great. A new version that you've sent me works fine now in my computer. (previewing)

However, created .d2v project file works only with GKnot and with my program if I used Tom Barry's version of mpeg2dec (mpeg2dec2.dll).

Anyway, you're getting close and you're doing a great job.

Good luck!

Thanks to all the beta testers

First thanks to all the beta testers. Thanks to you, I can commit some of my changes on CVS

Here is a little changelog of what I did :
- Optimized mmx/3dnow/sse motion compensation code (nothing changed on P4 code)
- Added SimpleResize (from Trbarry)
- Added the verticalReduceby2 filter from avisynth to do fast deinterlace (+ 3dnow/SSE simple optimization)
- some little optimization (less than 1% speedup) on some memcopy (Richard Berg gave me this idea in this thread :
http://forum.doom9.org/showthread.php?threadid=28568 )

My todo list :
- Add the Reduceby2 filter from avisynth (I need that)
- update mpeg2dec.dll as well with my modifications.

I won't be able to work on Dvd2avi till the weekend.

I hope I'm not doing something Nic has already done in his Dvd2avi ala Nic !!!!

Well as you know my "Dvd2avi ala Nic" (<-- Who first came up with that name? ) I do wacky things. your stuff sounds great Vlad.

(All my filtering comes straight from MPEG2DEC.dll & AviSynth.dll (even the resize)....)

I should really get round to releasing it (as ive given up on it recently, but just keep on using it to rip )

-Nic
