Producer: GL/CUDA Producer, Consumer: EGLStream::FrameConsumer

[hhami.20401]

Hi guys,
I need the following consumer to get the file descriptor of DMA buffer:
Argus::UniqueObj<EGLStream::FrameConsumer> consumer( EGLStream::FrameConsumer::create(eglDisplay , egl_str, &status));
For the above consumer, I need to create EGLStreamKHR using the code snippet below:
EGLint stream_attr[] = { EGL_STREAM_FIFO_LENGTH_KHR, 1 /*fifo*/, EGL_NONE}; egl_str = eglCreateStreamKHR(eglDisplay, stream_attr);
but I encounter “(Argus) Error BadParameter: propagating from src/eglstream/FrameConsumerImpl.cpp, function acquireFrame()”. It would be great if anyone can provide appropriate stream setting (EGLing stream_attr) for eglCreateStreamKHR(.) function to resolve the bad parameter error. Any sample code would be highly appreciated.
Sincerely,

Please check the MMAPI sample code if any help on it.

Thanks
