please look at the code snippet GstSample *videosample = gst_app_sink_try_pull_sample(GST_APP_SINK(ImPipe.appsink), 10 * GST_MSECOND); if (videosample) { nvtxRangePush("Video Buffer Processing"); GstBuffer *videobuf = gst_sample_get_buffer(videosample); Gst…

There is no update from you for a period, assuming this is not an issue anymore. Hence, we are closing this topic. If need further support, please open a new one. Thanks ~0910 Hi, We are not able to check further with the partial code. Please share a full sample that we can compile and run.

Hi, I review the links you provide but they are somehow “off topic”. They show how to access the NVMM data to be able to post process the frame data in your example to do some blurring or so. If comeback to the goal here: I have a gstreamer pipeline and I want to mix the video frame with GUI, qu…

Hi, The NvBufSurface can be mapped to EglImage. And then you can access it through EGL functions. Please search for related topics: Search results for 'NvBufSurface EglImage ' - NVIDIA Developer Forums

Can you provide me with the few line of code, in replacement of the code snippet I have provided, instead of guessing game. gLEGLImageTargetTexture2DOES is NOT supported by Nvidia YES or NO ? if no can you please provide the equivalent. Thks Michel

Hi, Please check There is no "glEGLImageTargetTexture2DOES" API defined in "libGLESv2_nvidia.so" - #3 by DaneLLL NvBufSurface can be mapped to CPU pointer, CUDA pointer, EglImage. Certain EGL functions may not be demonstrated in the samples. Please give it a try.

Hi, thank you, but you are still running into circle I’m NOT doing this for fun , this is a real work for me. Are you referring to NvEglRenderer class ? NvEglRenderer is a helper class for rendering using EGL and OpenGL ES 2.0. The renderer requires the file descriptor (FD) of a buffer as an inpu…

Hi, We are not able to give firmed answer to the query since there is no existing demonstration. Most EGL functions are supposed to work but it’s possible certain functions do not work properly. Would suggest you base on existing samples to try the EGL functions. There are also samples in /usr/s…

Can you please escalate to the next level. My question is quite clear. Regards Michel

Hi, We checked it and your proposal may not work. The tested use-case is as demonstrated in NvEglRenderer. Without X11, it may not work as expected.

Thank you for your work but the communication is difficult. My use case is: an GL window is created by the app, the pipeline app sink get the frame and display the frame inside the existing window/GL context. processing -> pipeline -> appsink ! …

Hi, Your use-case is not supported. In gstreamer, the memory copy looks required.

Hi,
You may share this sample:
Zero-copy EGLImage texture upload? - #17 by michelcalifornia

We can set up developer kit and check. glEGLImageTargetTexture2DOES() can work with X window as demonstrated in NvEglRenderer. Not sure whether it works the same with the gui app and we have to try on developer kit.
