Actually i am using dm6446 and osd layers can be set to only RGB16 and video layers can be set to RGB24 or YUV.
i have made changes in frame buffer driver to enable RGB24 on vid0. i wanted to use latest version of directfb because of its new features.. moving back to 1.1 version is not help full for me. anyways if you have patches for 1.1 i can try to port it to new version.. and i will continue my effort to enable RGB24 on 1.4 version .. thanks for the patch.
