Hi everybody !

For those of you who are concerned by speed, I have reimplemented part of 
yuvscaler so that it scales now much faster than before for the most 
currently used size conversion. Here are my figures taking into account the 
dowscaling only:
(given figures are average value between an Athlon500MHz and a mobil PIII 
1GHz, no MMX accelerated routines) 

Standard quality for (full-size 720x576) PAL frames to SVCD conversion
yuvscaler -O SVCD : 40 fps
Standard quality for PAL 16:9 frames to PAL 4:3 conversion:
yuvscaler  -O WIDE2STD : 45 fps

High quality for PAL frames to SVCD conversion:
yuvscaler -O SVCD -M BICUBIC : 20 fps
High quality for PAL 16:9 frames to PAL 4:3 conversion:
yuvscaler  -O WIDE2STD -M BICUBIC : 25 fps 

One question: is it worth now that I optimize the conversion from PAL 16:9 
frames to SVCD 4:3 frames? It all depends on the positive number of answers 
to this question ... 

Cheers to all off you,
Xavier
