Dear Everyone:
I am developing a project using xvid. The video is 720x576x25fps, VGA adapter
support only 16bit color depth.
Since the video card (ct69030 ) used in my project does not support overlay,
and only support 16 bit color depth ,I have to change the output of xvid from I420
to RGB565. However the decode speed slows down heavily!
If using I420 mode, the decode speed is about 80 fps.
If changing to RGB565, the speed is only about 30 fps.
So,
1) I wanna know that who has the most fast X86 assemble programme to
convert YUV to RGB565???
2) Do you have any sugestion for my project?
THansk very much!!!
