(I’ve been reading for a few months, and this is my first post!)

I have a use case (sorry, can’t give details) for >120 fps on TX2, Jetpack 4.2.1. I found https://devtalk.nvidia.com/default/topic/1006894/jetson-tx1/nvcamerasrc-gst-plugin-frame-rate-limitation/post/5154382/#5154382 , which achieved 240 fps on Jetpack 3.0 using nvcamerasrc. However, nvcamerasrc has been removed in favor of nvarguscamerasrc. The gst-inspect output for nvarguscamerasrc shows it as capped at 120 fps:

$ gst-inspect-1.0 nvarguscamerasrc

Is there a way to capture >120 fps video from a CSI camera on TX2, Jetpack 4.2.1? Thank you!

hello D3_cwhite,

please also refer to Topic 1056210, and you should replace the pre-built library with attachment to remove the 120-fps upper-bound limitation.
thanks

Jerry, thanks! Sorry I missed the duplicate - I will join that thread.

hello D3_cwhite,

Ooops, that pre-built library in Topic 1056210 was based-on JetPack 4.2/l4t-r32.1
your code-base Jetpack 4.2.1 was l4t-r32.2, please update this library (devtalk1062039_Aug30_r32.2.tar.gz) instead.
thanks
