[Mplayer-users] ffdivx benchmark

[Felix Buenemann]

Hi mplayers :),

actually ffmpeg decore still need lot of improvement to gain divxds speed, as 
you can see from results under heavy decoding load, performance gain through 
lowering of bandwidth via YV12 is quite small compared to loss in decoding 
speed:

(btw. test system was PIII 932, 124MHz FSB, i440BX chipset, 512MB, GeForce 
32MB DDR, Linux 2.2.19 and as memory bandwidth with the bx chipset is quite 
good, performance gain through YV12 should be bigger on K6 systems)
