DM6467 and Blend

Hi,

I have an application using DM6467 for capturing.

The OSD/Blend stuff works fine if I do

Capture_get (capBuf 422) -> Ccv_execute (ccvBuf, 420) -> Blend_execute (ccvBuf 420) -> H264 compression (ccvBuf 420)

But the OSD/Blend stuff is blinking on the screen if I do

Capture_get (capBuf 422) -> Blend_execute (capBuf 422) -> Ccv_execute(ccvBuf, 420) -> H264 compression (ccvBuf 420)

Please help!

To try to understand the issue better, if the blending works after you convert to 420, but not if you blend while the data is still 422, why do you need to do it in the order that breaks? Also would'nt the blending operation be functionally dependent on the color subsampling format so you would have to use a modified blending function?

I need to add images to the OSD. this requires 422 colorspace to work. that is the reason why we need to change. blending operations itself does not requirements on colorspace as long as they are consistent.
