Display buffer is slower than normal buffer?


Display buffer is slower than normal buffer?

Postby hsfishing » Dec 7, 2005 @ 10:08am

Hi all,

I want to display a YUV420 frame.
I do color space conversion first(YUVtoRGB) and write the data direclty into the display buffer, but I find it is faster if I write the data into a buffer malloced by myself. There is about 30% gap between these two method. Why?

Is there any solution? Thanks a lot!
