I have an application that is attempting to use nvhost-vic but it crashes with a “device not found” error. Listing the content of /dev shows a number of nvhost devices but not this one. Was this device deprecated? If not, how to I get it back or installed?
Hi,
We have Nvbufsurface APIs to use VIC engine. Do you call either function and hit the error? Do you observe the same on AGX Orin developer kit? Would like to know how to replicate the issue.
The latest release is Jetpack 6.1. If you use previous release, we would suggest upgrade to latest version.
Thanks for the reply. My Jetpack version is:
Package: nvidia-jetpack

I decided to re-flash the Orin with the latest and greatest with SDK Manager. The /dev/nvhost-vic (at least) does not exist. Does this mean that that device has been deprecated and I should be using another method to provide that functionality? BTW, this is code I’ve inherited from the original developer so I’m somewhat at a loss in tracking down why it is being used but I’m working on it. Should I, perhaps, be using Deepstream?
Hi,
We suggest use jetson_multimedia_api. There are NvBufsurface APIs for using VIC engnine for color/format conversion and resizing. The samples are installed to
/usr/src/jetson_multimedia_api
