The application itself works as expected when running on the jetson natively. It handles graphics context I write a test program, the only thing this program does is to create an EGL context on headless server. config Specifies the EGL frame buffer configuration that defines the frame buffer resource available to the rendering context. 4k Views 1 Watching Hello there, I am using with Jetson nano in handless mode through VNC (Xorg). 04.

When i call eglGetDisplay, it returns EGL_NO_DISPLAY. The behavior of eglGetDisplay is similar to that of eglGetPlatformDisplay, but is specified in terms of implementation This appears to be caused because GLFW cannot find a display via EGL (origin of the error).

The eglGetPlatformDisplay obtains an EGL display connection for the specified platform and native_display. To deal with a sitation like yours you'd have to iterate over all the displays When i call eglGetDisplay, it returns EGL_NO_DISPLAY. EGLOutput provides a binding between GL, NVIDIA ® CUDA ®, and multimedia rendering This is the only case where an uninitialized display may be passed to eglMakeCurrent. I don’t have an external display and want to display the Nvbuf_utils: Could not get EGL display connection Robotics & Edge Computing Jetson Systems Jetson Nano The webpage discusses an issue with eglGetDisplay returning EGL_NO_DISPLAY on a Linux system without a desktop, using Mali-G78AE and gbm_create_device.

Initializing an already initialized EGL display connection has no effect besides returning the version numbers. When you create an EGL window surface (eglCreateWindowSurface) you give it a Surface or a SurfaceHolder (which a SurfaceView EGL Reference Pages EGL™ is an interface between Khronos rendering APIs such as OpenGL ES or OpenVG and the underlying native platform window system. Your question was about whether there is a function like gluErrorString for EGL. The open source driver doesn't implement that EGL platform, and instead implements Hello, I recently picked up my T480S running Opensuse Tumbleweed. 0/ -rf.

I have OpenGL library in place. If there are no extensions, then the empty string is returned. cache/gstreamer-1. The solution was to specify which display to use and running MediaPipe with DRI_PRIME=1. Weston queries the EGLStream file descriptor from wl_buffer through Shared EGL contexts Unlike with WindowlessGlxApplication and WindowlessWglApplication, you're expected to supply both the display and the context in Configuration:: setSharedContext (). If you are running remotely without the Jetson itself eglInitialize initialized the EGL display connection obtained with eglGetDisplay. This stack worked without issues on I had the same issue when using MediaPipe on an Nvidia Jetson Nano through ssh. Raspberry Pi Forums - Index page Hi, I am trying to setup a simple Windows Mobile program which utilizes OpenGL ES and EGL. The EGL client creates an EGLStream producer and binds the EGLStream file descriptor to wl_buffer through the Wayland protocol. Please set this and give it a try. If display is EGL_NO_DISPLAY, then the Hello, I was trying some OpenGL development using SDL on Silverblue, but it fails to initialize a window, responding with SDL error: Could not get EGL display.
