AM625: AM625 Alpha blending

Hello,

Based on my internal discussion, the Global Alpha register is for the overlay manager and it is used to blend two images (one image in background and one image in forground). In your case, you have a single image and it's being displayed on a single video pipeline. Is the understanding correct?

Dear TI.

Thanks for your answer.

We use two interface LVDS and DPI so two pipeline has used. Can we setting blending with black background?. Or use one pipeline for two interface? (so we can use another interface for alpha blending) 

Thank for your support

Hello,

Could you please explain your setup? We have the following DSS image:

Are you passing two different images to the Video Pipeline and Video Lite Pipeline? Next, are you using the overlay manager to combine both images and passing that to OLDI or DPI?

Daer TI,

We use the same image (we use same dma buffer for both) for both DPI and LVDS. This is my setting

Vidl->overlay 0 layer 1->vp0 (LVDS)

Vid->overlay 1 layer 1->vp1 (DPI)

We also try use vidl for both overlay 0 and 1 but image become shattering.

For your question, please give me guideline for di that.

Thank for your support.

Do you have any example that I can try on my side?
