problem with mpeg2dec3

[Slav_User]

When I use LoadPlugin("mpeg2dec3.dll") and
TomsMoComp(x,5,1) (where x is 0 or -1) avisynth display an error message.
When I use LoadPlugin("mpeg2dec.dll") (downloaded from http://www.avisynth.org/users/warpenterprises for avisynth 2.52)
everything is OK.

What is the problem?

You may have a version incompatibility due to different color spaces between AviSynth 2.0x and 2.5x.

Create an .avs file with one line:Version() and open it with an AVI player or with VdubMod. To use mpeg2dec3.dll, if I recall correctly, you must be using 2.5x.

try the latest version of mpeg2dec3 (http://nic.dnsalias.com/)!

Version of Avisynth is 2.52, version of mpeg2dec3 is 1.08 .
Error message is following:

Avisynth open failure:
Evaluate: Unrecognized exeption!
(c:\folder\movie.avs, line 17)

line 17: BicubicResize(520,416)

Something strange happens with Teleside() function. When I use mpeg2dec3 plugin it requires YUY2 data. With mpeg2dec everithing is OK.

you have to define more parameters

for example:
BicubicResize(520,416,0.333,0.333) -> soft bicubic
BicubicResize(520,416,0,0.5) -> neutral bicubic
BicubicResize(520,416,0,0.75) -> sharp bicubic

But what about Telecide() function?
Why I have to use converttoYUY2() function before Telecide when I use Mpeg2dec3.dll?

[bond]

because mpeg2dec3 is used in avisynth 2.5 and avisynth 2.5 outputs yv12 (which should be faster most of the time than mpeg2dec, which outputs yuy2 i think)
read more about yv12 in the yv12 faq (http://forum.doom9.org/showthread.php?s=&threadid=37276) and avisynth faq (http://forum.doom9.org/showthread.php?s=&threadid=25002)!

if telecide needs yuy2 you have to put converttoYUY2() before it because otherwise it will get yv12
but perhaps there is also a newer yv12 enabled version available (use the search button)...

Tried BicubicResize(520,416,0,0.5)

Avisynth open failure:
Evaluate: Unrecognized exeption!
(c:\folder\movie.avs, line 17)

[Slav_User]

# LoadPlugin("Mpegdecoder.dll")
# LoadPlugin("mpeg2dec.dll")
LoadPlugin("mpeg2dec3.dll")
# LoadPlugin("decomb.dll")
LoadPlugin("TomsMoComp.dll")
MPEG2source("c:\temp\some.d2v")
TomsMoComp(0,5,1)

BicubicResize(520,416,0,0.5)

@slav:
What happens if you remove the resize and TomsMoComp then try to load the avs in virtualdub ?

Im back next monday properly so ill look at it more then...please post any findings :)

Cheers,

There is no need to remove Resize or TMC, I should only change first param in TMC from 0 to 1.

Why I have to use converttoYUY2() function before Telecide when I use Mpeg2dec3.dll? Because you are using a beta version of Decomb 5, which does not yet support YV12. You can use Decomb 4 for YV12 support until Decomb 5 final is released (within a week or two).
