DM365's component display

jun yang62451

Hi, Sir.

I have a question that DM365 can't correctly display 720P image through Component output.

On the DVSDK4, I modify encodedecode demo(use V4L2 display ) to display 1280*720 Yuv420sp data. The range of view on monitor is smaller than true image.

As show in the following illustration.

Q: Could you tell me How to solve this question?

Thanks!

In debug process. I find that BASEPX register can affect display area of image. But cannot display the total image range.

inaddition, Do I need to modify the VENC registers( HSPLS, HINTVAL, HSTART, HVALID...) for 720P display through Component YPbPr?

What value do these registers set?

Thanks!

Dear Marcus Cooksey, Thank you.

Does this question is reason of encode timing?

In DM365's VPBE spec, it describes that 720P display encode is accord to SMPTE-296M.

Does it support the other encode timing?

Use component YPbPr display image, Can VENC timing register( HSPLS, VSPLS, HINTVL ... ) adjust encode timing?

Thanks!
