Which one is faster in terms of uploading? OpenGL or EGLImageKHR?

Hi sirius850120,
Please share more detail about your usecase. What is the function of ‘oploading’?

TX2 display memory and memory is not a difference?
09_camera_jpeg_capture
CopyToNvBuffer (m_dmabuf);
NvEglRenderer.cpp

HglImage = NvEGLImageFromFd (egl_display, render_fd);

The two step is uploaded the memory upload to memory?
Which is more efficient than using glMapBuffer directly?

Hi wuliming,
Below function does not perform memory copy.

HglImage = NvEGLImageFromFd (egl_display, render_fd);
