Video can not real-time refresh

I build my program on tx2 and interface programming using QT.
My video is get from FPGA,and then I inform ui to refresh.
The problem is that I have receive many frame but it just refresh one frame.
Maybe the drawing mechanism is inefficient,Is a good way?

We don’t have much experience in QT. Hope others can share their expertise.

We have NvEglRenderer in tegra_multimedia_api. It is X11-based and you may also give it a try.

Could you give me some instruction about how to use NvEglRenderer.

Hi, We have several samples demonstrating the functionality of NvEglRenderer. Please check


Please install the samples via Jetpack.
