XviD Decode issue

[c0952594549]

　

When the full screen has the red object, it will generate the mosaic.
For example: red taillights

But ffdshow no problem, occur only on XviD codec itself.

Sorry, I didn't understand a word you said. What mosaic? What taillight? :confused:

P.S: Only thing I understood was that movie is Constantine :o

Look at below picture.
Edge has aliasing and alias fill.

But ffdshow no problem, occur only on XviD codec itself.

Please use the ffdshow test, compare...

That whole screenshot is so blocky, I cannot make out what is so special about the areas you circled. Can you provide a sample? Else how would I compare with ffdshow?

Install FFDShow MPEG-4 Video Decoder (http://www.free-codecs.com/download/FFDShow.htm) to compare.
XviD Decoder has aliasing and mosaic in red edge.
FFDShow Decoder no problem.

ffdshow has higher quality upsampling. Try searching for say YV12, upsampling, chroma, etc.

YV12 effect not good. still has little alias mosaic.
