Is there any tools for debugging Video Application?

[sumin.lee]

Hello,
We are testing decoding and playing 4K video on Xavier NX.
We can use H/W decoder via ffmpeg.
And we build the video application on QTAV.

There is no issue when Full HD video is playing with real-time decodeing.
But 4K Video has buffering for playing.

We want to debugging or verifying the application.
Is there any tips or tools for the solution?

Hi,
You can run sudo tegrastats to check the system status. It is introduced in developer guide:
https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3261/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/AppendixTegraStats.html#

And please executing sudo nvpmodel -m 0 and sudo jetson_clocks to run at maximum performance mode and check if there is improvemnet.
