How to clear ddr residual memory in vdma application

Jump to solution

I need to input a low resolution video and output to a higher resolution using VDMA

No resizing is needed. The video input is expected to be placed at the top left corner of the output screen.

I expected that there should be black screen at  the right edges and at the bottom. Instead, the right edges and the bottom screen keep flashing. A video clip is enclosed below.

My question is how to blank the flashing area
