[Spice-devel] give me some advise how to improve display effect and decrease client cpu usage

[bigclouds]

hi,all
i have used spice for a long time,it is good, but in pratice it needs improvement, like resource usage, network bandwidth,performance.
1.it eats up much cpu on client side, up to 90% when play video. i am sure whether decompression or something else uses so much cpu. if  client (remote-viewer) is corss-compiled to arm platform, what will happen?  iordan has succellful compiled it to android platform.
how to decrease cpu usage on client side?(if Mplayer which Fedor  has mention will help )
2.how to improve display effect and decrease network usage.
now glz algorithm seems the best, but display stuck, and mosaic (video screen not sync) exist. 
better network leads to larger traffic, some time it goes up to 7M/s.  in future spice client will be  often used  in WAN , in that case the less trafic the better.
 
guys , do you have some ideas?
 
thanks
