[codecman]

hi,all
i'm starting to develop a video palyer on symbian,s60 v3 fp1
1st of all,there is something i want to figure out clearly,

1,about DSP,
we know,nokia don't public any api on dsp,for it's level kernel ,but it develop some app use dsp,for ex,mmf mp3,video scale,
i doubt if the realplayer in my e65 does use the dsp instuction while decode realvideo 89?
if did, i feel their work is not good, because of it's bad performance.
smart movie ,coreplayer ,whether these sotware has permission to use c55 dsp directly?

2,how can i use those codec optimized by nokia or ..
for example,if i have a video clip which video =h264,audio=ra8
can i use the C55 dsp based optimized realaudio codec in realplayer.

3,about yuv to rgb 565
for speed,i looking for a fast algorithum ,such as use table, even 4 pixels once time,
my question : since nokia has developed some player app,it must do yuv rgb tranfer, did C55 dsp do this work? if so, why not public api?

thaks lot, my email kenjem@gmail.com
