mpeg2dec for v2.5

WarpEnterprises · 7th January 2003, 08:48

mainly @dividee: could you please re-compile your mpeg2dec for v2.5 as it seems to me as one of the best-tested around and therefor quite helpful for switching to v2.5 (as reference and 'working for sure')?
(of course only with YUY2-output)

Thanks.

Convolution3D, YUY2 version, crashes.
Should I use ConvertToYV12 and Convolution3D YV12?

sh0dan · 7th January 2003, 19:28

"Convolution3D, YUY2 version" is an 2.0 plugin, and cannot be used in 2.5. So, yes, do the convertion stuff!

Guest · 7th January 2003, 19:42

I'm working on a quick hack to make dividee's version deliver YV12.

Assault · 7th January 2003, 19:42

@ Frank
I think you don't have to do the conversion because Convolution3DYV12 works in both YUY2 and YV12 colourspace. Please correct me if I'm wrong.

Regards
Assault

EDIT: Ok I was wrong. Convolution3dYV12 works only in YV12 colourspace.

neuron2 is there any reason why you plan to do this? Is there something wrong with MarcFD's MPEG2Dec3? I did read the thread you started about it, but I thought the issues were fixed?

Bye,

my main reason why I like dividee's version is the MISSING of options.
IMO it should take the mpeg and decode it as authentic as possible.

I don't think it does anything to your MPEG's unless you specify it.

But, I think the problem is rather (lack of) documentation. I see there are many options. 1) I don't understand half of what they do. 2) The syntax is ... well ... let's say ... alternative. 3) Half of the things you must know about it, you have to dig through several large threads to figure out.

Actually the issues have not been fixed. I am still doing some
more testing, this time I have installed the latest avisynth 2.5
alpha dll. I did an avisynth2 encode of an MPEG2 clip fixed with Pvastrumento.
Curiously this one gave me no problems and I converted this to KVCD
(an MPEG1 encoding using Tmpgenc) and XviD. I will keep testing.

I believe some are still reporting problems with mpeg2dec3. In any case, the change will be very slight to mpeg2dec to make it deliver YV12 (nothing like the massive overhaul that was done for mpeg2dec3). This will allow us to have a "reference" version that is well-tested and reliable. I want it to help me track down some strange problems I am having. Didn't see any harm in making it available.

Guest · 10th January 2003, 00:17

It turns out that the reported problems with mpeg2dec3_094 were due to other issues and not bugs in the DLL. Therefore, I have put on the back burner a YV12 version of dividee's filter.

However, I have rebuilt the YUY2 version with AvisynthPluginInit2() as requested by sh0dan. I have attached it.

Donald,

The problems your speaking of were actually an issue with AVS 2.5 or different filters? I haven't heard MarcFD mention anything about it yet so was just curious.

The two guys that reported problems have both now attributed them to other issues in their respective threads. I have not experienced any problems with MarcFD's version 094, so the urgency appears to be no longer there. Anyway, MarcFD is fully capable of fixing any bugs that might come to light.

"Repeating Frame" bug is not occouring in this Version as described in this thread http://forum.doom9.org/showthread.ph...1&pagenumber=4

but its slower

HarryM · 10th January 2003, 10:40

Mpeg2Dec3 from Marc is buggy??? I use v0.94 still.
This bug is only 'field decomb' related or 'frame - non interlaced' too? I dont use interlaced material.

Marc FD · 10th January 2003, 17:26

hi.

compile an avs 2.5 mpeg2dec version is not a bad idea, i did it myself two months ago, didn't tought someone would found it usefull ^^.

about YV12, it's the bigger change in MPEG2Dec3, so i don't think you can add it so easily IMHO. i think the minor bug is related to my conversion btw.

Marc, what is the minor bug you refer to? A list of the known bugs in 094 would be useful. Thank you.
