[RESOLVED] MPEG-2 distortion with v2039

[Ajidamal]

First of all, just want to say thanks to admin for developing this tool - I've been using it a lot over the last year and it's been absolutely invaluable for decoding HD.

However, since upgrading to version 2039, I've been encountering problems using it to decode MPEG-2 videos. Specifically, I've noticed that there's a certain amount of distortion around moving sharp edges, this being particularly visible in programme credits. When I revert to v2038 or earlier builds, the problem disappears.

The following is an example MPEG-2 elementary stream where the effect occurs throughout:

Using the following simple AviSynth script:

Code: Select all

LoadPlugin("C:\Program Files\DGDecNV\DGDecodeNV.dll")
LoadCPlugin("C:\Program Files\megui\tools\yadif\yadif.dll")
DGSource("sample.dgi")
yadif(order=1)
Spline36Resize(480,270)

this is a sample frame after using v2038 to index and decode:



whereas this is using v2039:




The card I'm using is a GeForce GT 220, running version 266.58 (6.14.12.6658) of the Nvidia drivers on Windows XP. I've also tried the latest version of the drivers (270.61), but it makes no difference.

Any help would be greatly appreciated.

I have it fixed and will slipstream it later tonight. Watch the News thread for 2039 to see when that happens.

Thanks for pointing this out.

OK, you are good to go. Redownload 2039 and update DGIndexNV and DGDecodeNV.

That was fast! Just tried out the new version and everything seems fine now. Thanks very much.
