SK-AM62A-LP: MSC (tiovxmultiscaler) causing frame drops.

Sathiya Narayanan
Intellectual 810 points

Part Number: SK-AM62A-LP

Hi,

I am using SK-AM62A-LP board with SDK 9.2 for 4K@30fps streaming.

Resolution: 3840 x 2160
Framerate: 30 fps
Sensor: IMX334

For my network streaming, I need to downscale my 4K image to 1080p, for that I am using tiovxmultiscaler element. But I have noticed that using that element causing framerate reduction. My framerate reduced into half (30fps -> 15fps).

I also noticed one fascinating thing. Regardless of downscaling, framerate reduction is there for simple passthrough also. Isn't tiovxmultiscaler element is DMA backed?

Here is the normal pipeline for 4K@30fps without tiovxmultiscaler:
