Hi, Wondering if anyone has any insight into OSD transparency on the dm355.
Specifically, I'm unclear on the role of OSD_OSDWINnMD_TEn and OSD_OSDWINnMD_BLEND_FACTOR with regards to the behavior of the attribute layer. If I put OSD1 in attribute layer mode and want it to control the blending on OSD0, do I set these registers for OSD0 or OSD1? Also, the VPBE user guide writes that if transparency is enabled, then the pixels that are equal to the color key will be blended by the blending factor. Do I need to write the desired blending factor into each pixel of OSD1, or will it be configured by setting OSD_OSDWINnMD_BLEND_FACTOR? And once again, do you write that in the OSD0 or OSD1 register? Finally, if I enable color keying, enable transparency, set my blending factor to maximum transparency, should I expect every pixel in OSD0 that equals the color key to be transparent? Do I need to write something into OSD1 at that same pixel location to make it work? The only documentation I've found on this is the VPBE user guide, so maybe there's a better resource out there for this information, any help would be appreciated. Thanks!
