I am working on a project where adv7625 is configured as RX for Adv8005 & Adv 7619 is also used for external OSD overlay.
Currently Adv7625 & Adv8005 with Adv7619 as external OSD code is working fine.
I can see video after switching the RX i/p from Adv7625 to Adv7619.
I am only configuring I2C registers & in my project currently there is no provision for SPI.
I have also tried to set alpha using VSP_set_EXOSD_ALPHA_FMT api in my code, but its not working.
My question is that how can I set alpha or how to make video transparent for Adv7619 (external osd) video over i2c so that it can be blended with the incoming video from Adv7625.
