[FAQ] PROCESSOR-SDK-J721S2: Runtime configuration of Global Alpha value of a video pipe from openVX control command

Hi,

Apply the following patch in the pdk and video_io directory.

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/global_5F00_alpha_5F00_update_5F00_pdk.patch

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/global_5F00_alpha_5F00_update_5F00_video_5F00_io.patch

cd $(PSDKRA)/pdk_j721s2_xx_xx_xx_xx;
git apply global_alpha_update_pdk.patch;

cd $(PSDKRA)/video_io;
git apply global_alpha_update_video_io.patch;

Once the patch is applied rebuild the sdk.

Now global alpha value can be changed during runtime by sending control command to display node in the openvx application.

Regards,
Gokul
