MPEG2Dec3 v0.9 for Avisynth 2.5

[Marc FD]

a lot of work for this pre release of the stable version.
and i've spend a lot of time on documentation, i'll try to clean the code more in the next days to be able to package it. (in v1.0)

dl it on my site (link below, in my signature)

i hope you'll enjoy the old&new features.
i'm sorry, defaults parameters aren't implemented but i'm thinking of it.
it's piece of cake now, because the harder stuff on the Avisynth API (~ 1000 lines) is done ^^.
BTW, i think i may add a fixed quant YV12 postprocessor (would act like if source was at a fixed quant. less efficent, but can still be usefull)

i dunno if i should add fastest colorspace convertions. say me ^^

going to sleep now XD

Regards,
MarcFD

PS @Sh0dan : do you know if dividee is going to make a YV12 version of compare ? i've a new quality mesure (coded for YV12) that Mfa gived me a long time ago, i could add it and do the YV12 convertion if you want.

Thank's for your great job.
I will test mpeg2dec3 soon.
but before I have to sleep, like you

SeparateFieldsYV12 is really interesting.
I often use it as you know.

merci....

Thanks so much for the new build Marc. Documentation is much better

The custom CPU settings looks great, cant wait to test it!

Edit- For some reason lumoff=-1 is being reported as an invalid argument sometimes. I got it to work twice but it's not consistent I'm using sh0dan's 07112002 2.5 build and the script is-

LoadPlugin("C:\Program Files\AviSynth2\plugins\MPEG2DEC3_YV12.dll")
LoadPlugin("C:\Program Files\AviSynth2\plugins\undot.dll")
mpeg2source("D:\test\breed.d2v",iDCT=2,lumoff=-1,cpu2="xoooxo")
crop(4,4,712,472)
UnDot()
LanczosResize(640,352)
Limiter()

please read the doc. due to the YV12 colorspace compatibility, LumaFilter and colorspace convertions are indepedant filters. this way, it's much more user friendly, code get cleaner, and you can use it WITHOUT MPEG2Dec3 decoding. you just need YV12 colospace.

LumaFilter() will do lumoff=-2 lumagain=1 by default (i thinked at iago and users who use is combo)

dunno if a sharpen2 YV12 could help to temporary replace Unfilter in iago's combo ? maybe it's worth to check ?

i did it thinking of you ^^

@Marc

Thanks a lot for the new version! I'd been waiting for it for days to start some real YV12 tests/encodes. Also, the documentation looks really sharp too!

regards,
iago

i've finished 0.91 (with bugfixes & default settings), but can't release it ^^
sorry, i need to go right now. i would release later ^_^

Dividee is very tied up at the moment, as far as I understand, but I'll see if I can do an YV12 version soon. This and Blankclip is probably top of the list right now. Layer would be nice, but it seems like a big task (haven't looked at the code at all).

@Marc FD,

Thank you for your latest MPEGDEC3 v0.9,
with latest AVIsynth 2.5 (build 7/11) & Koepi's XviD build 9/11,
1-pass quantizer @ 2, without b-frame,
I got ~30fps on my Athlon XP 1700+, That's fast!

[Marc FD]

Okay, v0.91 is out.

Changes :
- cleaned a bit more the source
- added MPEG2Dec3.def default settings loading (like don's filters)
- bff mode in SeparateFieldsYV12

(and bugfixes)

dl on my page, as usual.

if you really want to do it, okay. but i know very well the source, and i've improvements to do, so i though i could handle it. just say me.

>This and Blankclip is probably top of the list right now.

Blankclip should be easy to do in YV12 ^^

>Layer would be nice, but it seems like a big task (haven't looked at

layers would be so easy to convert to YV12, no ? i can do it if there's any request for it ^^

BTW, i'm gonna make a YV12 version of subtract (with MMX code for all colorspaces) because i often use them and i don't want to use Avisynth 2.06 anymore. i can e-mail you the code when it's finished, ok ?

[sh0dan]

Feel free to do all this - it would be nice if I could focus on brushing up other stuff now.

The best way would really be for you to have CVS access. Version control would be 10x easier than mailing changes back and forth. You should contact Richard about access.

[Marc FD]

okay i'm gonna mail him ^^

[wotef]

i'd love to have layer, thanks marc

Hey I tried this decoder today and in the readme it says to use:

MPEG2Dec3("filename.d2v")

But it says it's an invalid command. Using MPEG2Source still works though, but is that the proper way to do it?

I noticed the same thing last night when I tried it. I got a speed increase (though only 10 %) with it, so I guess YV12 was at least used in some way.

[ACClarke]

it's just a mistake
Marc knows it, he 'll probably correct it in the next release.

mpeg2source is the right keyword

[dattrax]

stupid question, but I went to your web site and there is only beta 0.6 for download and not 0.9 as advertised.

am I going daft?

@dattrax
its there.The build is 0.91 and downloaded a couple of days ago.try to clear your browser cache

[dattrax]

Just done that, and it's still reporting version beta 6 as the latest. The odd thing is that I get the same page at work as I do at home.

You're scrolling down too far. Check under avisynth 2.5 filter, not 2.06.
