HI,every one!

i want to overlap some texts (such as time,weather)on my videos,  is there any hope for this by OSD? is there more DETAILS about how to use OSD?

I used ezsdk5-3-15- omx demo---capture_encode to capture camera date,display and encode . But I can't find HDVPSS/OSD module in ezsdk.

thanks,

mk

    Hello,

    There is some basic description for OSD in the DM816x TRM and DataSheet, in HDVPSS section.

    Also these links may be useful:
