Text/Image overlay on VPU data using IPU

I want to overlay text on the data returned by VPU.

When I play AVC data the mxc_vpu_test.out always outputs NV12.

Also when I use the above test case with IPU_PATH, I do not see any video on screen.

It works only with V4L2.


DirectFB cannot perform overlay unless this video is rendered as ARGB.

Reference for failed color space conversion.


Please suggest a solution to get overlays working on IMX6Q using DirectFB or any other API providing direct text overlay API.
