[MPlayer-dev-eng] Software scaler regression

[Matthias Wieser]

Hi,

some time ago I did software scaler comparisons
(http://home.knuut.de/MWieser_/index.html).

Last time I rerun my script I created difference images between
old and new ones.

Between Oct. 12 and Oct. 26 changes went in that made
- sws 1 produces errors when you scale to n*8+x  (1)
- all software scaler produce worse colors than before (2)
 
What did I do?:
------------------------
mplayer raw_detailliert.avi -ss 00:00:07 \
-vf crop=624:504:48:36,scale=412:352 -sws [0-10] -frames 02 \
-vo png -nosound -z 0

convert -scale 624x504! 0000002.png 0000002_.png
------------------------


The Images:
