GL Producer CUDA consumer in EGLStream

[hhami.20401]

Hi guys,
I need a example code that utilize EGLstream in TX2 and Producer is GL and consumer is CUDA? I wrote my self a code for that but when I acquire frame in CUDA, pitch value of frame is 0 and frame is invalid.
Thanks,

Hi,
Please run

$ /usr/local/cuda-10.2/bin/cuda-install-samples-10.2.sh /tmp/

And check the sample:

/tmp/NVIDIA_CUDA-10.2_Samples/3_Imaging/EGLStreams_CUDA_Interop

Thanks for your replay,
I used this example “/tmp/NVIDIA_CUDA-10.2_Samples/3_Imaging/EGLStreams_CUDA_Interop” for my source but it is CUDA producer and CUDA consumer with Eglstream I need GL producer and cuda consumer. Is there any source for my case ?

Thanks so much

Hi,
This method may not work properly. Generally we use either pure EGLStream producer/consumer or CUDA producer/consumer. It may not work to mix the functions.

EGLstream DMA Consumer solutions

Hi guys, There are two solution for DMA Consumer in EGLstream at Tegra devices using nveglstreamsrc plugin which is close source and I’m not sure if it is zero copy or it has HW copy and other problem is it needs Gstreamer. using Argus Interfaces Argus::Status status; Argus::UniqueObj<EGLStream::FrameConsumer> consumer(EGLStream::FrameConsumer::create(eglDisplay ,egl_str,&status)); iFrameConsumer = Argus::interface_cast<EGLStream::IFrameConsumer>(consumer); Argus::UniqueObj<…

So that we can suggest next.
