Hi，
I am workink with the DM8127_IPNC_RDK3.8.
I want use M3 swosd to add icon to the YUV frame.
I want the icon's background to be transparent.
Refer to the <<SoftwareOSD_UserGuide.pdf>> section 5.10.1 User Defined Transparency ,"In this mode, if pixel value of OSD bitmap window is within the range of transparency value plus/minus transparency range, the pixel becomes transparent. "
And I saw the code:
bmpWinPrm.transperencyVal = SWOSD_OSDBLACKTRANSVAL; //0x00
bmpWinPrm.transperencyRange = SWOSD_OSDBLACKTRANSRANGE; //0x48
What's the mean of the transperencyVal and transperencyRange for YUV frame? Is for Y, for U, or for V or other value?
Thank you for your reply!
