Hi NV，

We run the same G-streamer pipeline.
When running on the xavier platform, the following error is reported.

When running on the orin platform, there is no error.

Part of the pipeline：

nvv4l2camerasrc device=/dev/video${INPUT_NUMBER} do-timestamp=TRUE ! \
nvvidconv ! video/x-raw(memory:NVMM), width=960, height=540, format=(string)I420 ! tee name=t_raw_fps_${INPUT_NUMBER} ! nvvidconv ! videorate ! video/x-raw(memory:NVMM),framerate=5/1 ! nvvidconv ! tee name=t_raw_camera_nv_${INPUT_NUMBER} ! nvvidconv ! video/x-raw(memory:NVMM), width=960, height=540, format=(string)BGRx ! \
nvvidconv ! fakesink async=false

Please help answer the following questions:

On which hardware module does the plug-in ”videorate“ run?
Does the ”nvvidconv“ run on VIC?
3.Video Imaging Compositor (VIC) performance differences between Xavier and Orin platforms？

Thanks！

Hi,

This is a software plugin to change frame rate. We are uncertain about the detail. But it does not use any hardware engine.

Yes.

Yes. Maximum rate of the engine is different. Please check

Jetson Orin Nano Series, Jetson Orin NX Series and Jetson AGX Orin Series — NVIDIA Jetson Linux Developer Guide 1 documentation
Jetson Xavier NX Series and Jetson AGX Xavier Series — NVIDIA Jetson Linux Developer Guide 1 documentation

VIC in AGX Xavier can run to1036.8Mhz which is higher than AGX Orin.

Hi DaneLLL,

So can I simply assume that the VIC performance of the Orin platform is lower than that of Xavier?

DaneLLL · May 31, 2024, 7:34am

Hi,

Yes, this is correct.

Hi DaneLLL,

Thanks!
