hi, i got a 4:2:0 video frame, 720P , but paded with 32 pixes of each side((1280+32+32)*(720+32+32)) ,

i want to use VDCE to convert it to 4:2:2 , 720P. Then what should i do? Can anybody give me an example?

You will need to provide offset-pointer to video frame to account for padding. I believe yu can do this via FBDEV API (you can for other DaVinci platforms) but I can investigate further if you have problems figuring this out.

Additionally you will need to set VDCE CTRL register, VCDE_MODE field to 3 (see http://focus.ti.com/lit/ug/sprueq9/sprueq9.pdf for more details).

Hi,

You can set the line offset in the VDCE driver also. Moreover, you can provide exact location of the frame in the buffer by using user pointer buffer exchange mechanism.

Thanks,
