gstBufferManager -- failed to map EGLImage from NVMM buffer

[Kajatin]

Hello,

I have updated my jetson-utils clone today with the latest changes in main and videoSource started giving me problems.

It seems like it can't get the frame from my RTSP camera. I'm running on a Jetson Xavier NX dev board. Please see the attached logs.

Note: If I disable ENABLE_NVMM, it works. I wonder if I could potentially get better performance with nvmm? Otherwise I'll just build with this flag off, and then it all works just fine.

[dusty-nv]

Hi @Kajatin, yes you typically can get better performance with using NVMM, but it seems in some circumstances it does not work (I am still trying to find out why). So for now please continue building it with ENABLE_NVMM=off, thank you.

[Kajatin]

Thanks for the update @dusty-nv . I will continue building it with the flag off.

[edrethardo]

Stupid Question: How do I set the parameter ENABLE_NVMM=off? I'm building python applucations and am nit sure how to use building parameters. Do I have to build this repository on my jetson Nano with the parameters in the CMAKE file?

[Kajatin]

When you build this project using cmake, you can pass in settings to the executable like: cmake -DENABLE_NVMM=off [rest_of_the_command].

[phongphuhanam]

I built with ENABLE_NVMM enable and faced the same problem when I used Jetson Nano in headless mode. If the LightDM GUI is enabled , everything works fine. Hope that it will help you solve this issue.

[Vinu-Suhas]

i have my jetson kit in remote dekstop connection may i know how to enable lightdm gui

Hi @Vinumax969, see here: https://github.com/dusty-nv/jetson-inference/blob/master/docs/pytorch-transfer-learning.md#disabling-the-desktop-gui

[adnan4502]

Hi everyone, may i know how can i disable nvmm? I didn't understand from the conversation. Is there any tutorial available?

[dusty-nv]

Hi @adnan4502, rebuild it with the -DENABLE_NVMM=off cmake option:

cd jetson-inference/build
cmake -DENABLE_NVMM=off ../
make
sudo make install

[adnan4502]

@dusty-nv I found your comment and did the same..Now I am facing another error. **[cuda] unknown error (error 999) (hex 0x3E7) [cuda] /home/nano-jetson/jetson-inference/utils/cuda/cudaYUV-NV12.cu:154 [cuda] unknown error (error 999) (hex 0x3E7) [cuda] /home/nano-jetson/jetson-inference/utils/cuda/cudaColorspace.cpp:42 [cuda] unknown error (error 999) (hex 0x3E7) [cuda] /home/nano-jetson/jetson-inference/utils/codec/gstBufferManager.cpp:435 [gstreamer] gstBufferManager -- unsupported image format (rgb8) [gstreamer] supported formats are: [gstreamer] * rgb8 [gstreamer] * rgba8 [gstreamer] * rgb32f [gstreamer] * rgba32f [gstreamer] gstDecoder -- failed to retrieve next image buffer segnet: failed to capture video frame [gstreamer] gstDecoder -- end of stream (EOS) [cuda] unknown error (error 999) (hex 0x3E7) [cuda] /home/nano-jetson/jetson-inference/utils/display/glTexture.cpp:360

What can i do to solve this problem? please help me

[dusty-nv]

@adnan4502 can you copy & paste the console terminal log from the beginning of running video-viewer?

Also I don't believe the OpenGL display will work over SSH / X11-tunnelling because it uses CUDA/OpenGL interoperability. Instead please use RTP to view the video remotely: https://github.com/dusty-nv/jetson-inference/blob/master/docs/aux-streaming.md#transmitting-rtp

hey again, I tried but failed sadly at first...but then i tried it with opencv in a python program and it worked.
