Tool/software: Linux
I need to composite 2 DMABUFs captured from 2 different VIP ports on the AM5728. I am using the ti-gc320-tests git repository and the Vivante GC320 PDF documentation as examples.
So far, I can feed DMABUFs from the VIPs into the GC320 and successfully do things like Pixel Format Conversion, Scaling, and Rotation. What I need to do now is compositing.
Specifically, I am studying the example code in:
ti-gc320-test/tests/src/test/hal/common/UnitTest/units/gal2D/MultiSourceBlitRotation/101/101.c
When I implement this code into my existing test application, I always get the error: "gcvSTATUS_NOT_SUPPORTED" when I call gco2D_MultiSourceBlit. Here is the function in my test application:
/**
* gc320 renderCompositedFrames()
* Purpose: Perform a render cycle for compositing 2 input rames together
*
* @param inputBuffer1 - DMABUF type input buffer
* @param DMABUF type input buffer
*
* @return inputBuffer2 - Return bool success or failure
*/

Is multisource blitting not supported? If it is, what is wrong with the code above? Thank you for the support.
The documentation states that it is supported:
