Hi Xueming,

Which linux kernel version you are using? If 2.6.37, seems like SD_VENC composite (CVBS) timing entry is not supported, see the below wiki:

processors.wiki.ti.com/.../TI81XX_PSP_VPSS_Video_Driver_User_Guide

You can adjust the timings directly in the DRA64x HDVPSS SD_VENC registers, available in DRA64x HDVPSS user's guide.

Regards,
Pavel
