Hi there! My mission is to share DMA-Video-Buffers across processes with zero-copy. about my system: cat /etc/nv_tegra_release # R34 (release), REVISION: 1.1, GCID: 30414990, BOARD: t186ref, EABI: aarch64, DATE: Tue May 17 04:20:55 UTC 2022 Until r32 I used NvBuffer, took the fd from it using Ex…

Hi, Please upgrade to Jetpack 5.1.3 and check/try the sample: /usr/src/jetson_multimedia_api/samples/13_argus_multi_camera/

Hi, JetPack 5 supports NvSCI which provides utilities for streaming data packets between different applications and for inter-process communication (IPC). Please give it a check to see if it can meet your requirement. Thanks.

Thanks for your quick answer! [image] AastaLLL: JetPack 5 supports NvSCI which provides utilities for streaming data packets between different applications and for inter-process communication (IPC). Please give it a check to see if it can meet your requirement. I checked the documentation (…

Hi So this thread got flagged with nvbugs. Does this mean, that in a future release there will be an interface to cast NvSciBufObj to a NvBufSurface? Thanks for your time Markus

Did you solve the problem? I also encountered this problem, could you share the solution？thank you !

Yes, I was able to resolve the problem using EGLStreams and cuda on the Producer side and the gstreamer element nveglstreamsrc on the consumer side. It works kinda like this consumer: eglCreateStreamKHR() int fd = eglGetStreamFiledescriptor() cuEGLStreamConsumerConnect() // this happens in the gs…

Hi,
NvBufferTransformEx() is deprecated on Jetpack 5. We are checking with our teams whether there is solution for replacing it.

Low-latency, reliable way to overlay on top of camera images with Orin and ISP
