Producer-side steps:

  1. Receive the stream file descriptor through the socket (given as an eglstreamsocket argument) and create the stream (refer to nvgldemo_main.c): 
    eglCreateStreamFromFileDescriptorKHR(demoState.display, fd)
  2. Create the EGLStream surface (refer to nvgldemo_main.c). 
    eglCreateStreamProducerSurfaceKHR(
                    demoState.display,
                    demoState.config,
                    demoState.stream,
                    srfAttrs)
  3. Create EGLContext and eglMakeCurrent on the EGLStream surface created in step 2.
  4. Start to render the frames and eglSwapBuffers.
