Hello,

I am trying to play an mp4 file with my imx233 board. I am using 16 bit display. When I boot up the board, display is initialized properly and I see console outputs on the screen. When I open some sample videos which I loaded into filsesytem using gplay, it seems gplay is OK. The file is started to play but on lcd screen there are much of colors streaming. Should I modify my videos according to 65K colour gamut before trying to play ? Or it is already done automatically by gplay on the fly?

Regards,

I'm not sure but I think it's a bug in the new kernel, I tried 16 bpp mode driver and the screen distorts, with the old kernel (stmpxxx) this driver worked fine, but maybe it's just a bug in my code.

I also got some distortions. The distortion related to my screen seems mostly on the edge of objects int the stream. Especially red colour distortions. I think it may be related to rgb conversion to 16bpp from higher colour depts. What do you think ? Which kernel gives more suitable results ?

I am using 2.6.31. Which kernel should I use for better results ?

I am using the patch file you gave me for imx23evk, Thanks,

Hi,

Where can I find stable version for 16 bit system mode driver? Thanks

Sorry, but I was talking about 16 Bit Per Pixel driver for ssd1963 with 8-bit 8080 system interface.

Ok. What kind of distortion you were seeing ? It may help me comparing with my case ? And what kernel version you got stable result with your 8-bit interface?Thanks,
