[FAQ] PROCESSOR-SDK-J721E: How to enable blending operation and two input video pipelines in DSS memory to memory path?

Brijesh Jadav

DSS WB path can take input from the overlay manager output and overlay manager in the DSS can take input from two video pipelines and can blend the images and can send it out. In the current PSDKRA6.0, SDK supports only single input path for DSS memory 2 memory driver. This article shares the patches to enable second ie two video pipelines for this memory to memory driver.

Please find attached list of patches, which allows to use two video pipelines in the DSS memory 2 memory path and same node in the OpenVX.

1, PDK_DSS_M2M.patch: This patch needs to be applied on top of ti-processor-sdk-rtos-j721e-evm-08_06_00_12\pdk_jacinto_08_06_00_31 folder. This contains simple change in the DSS M2M driver to allow at max two input video pipelines. I also have updated PDK DSS M2M example to use two video pipelines.

2, TIOVX_DSS_M2M.patch: This patch needs to be applied on ti-processor-sdk-rtos-j721e-evm-08_06_00_12\tiovx folder. This patch modifies DSS memory to memory node and it can now accept two input images for the two input video pipelines.
