at the following link an example on how to load and display a YUV420 planar image on a PIP window: PIP_YUV420P


Awesome. Thanks for that. I see from the code that the U and V planes are interleaved. I wasn't aware of this. That's not how the official format is specified. Fortunately, this isn't going to be a problem, as the plane alignment requirements remain the same.

Currently I don't a way to create a 410P image, but it should be quite trivial to modify the 420P example.


Yes, it should be fairly trivial, as a 410P image follows the same idea as 420P except that the U and V resolution is 1/4 that of Y instead of 1/2.

Hope this help.

It definitely does. Thanks again.
