Hi,
Not sure if EGL APIs work, but the following demo code works:

    if (ctx->enable_cuda)
    {
        /* Create EGLImage from dmabuf fd */
        ctx->egl_image = NvEGLImageFromFd(ctx->egl_display, fd);
        if (ctx->egl_image == NULL)
            ERROR_RETURN("Failed to map dmabuf fd (0x%X) to EGLImage",
                    ctx->render_dmabuf_fd);

        /* Pass this buffer hooked on this egl_image to CUDA for
           CUDA processing - draw a rectangle on the frame */
        HandleEGLImage(&ctx->egl_image);

        /* Destroy EGLImage */
        NvDestroyEGLImage(ctx->egl_display, ctx->egl_image);
        ctx->egl_image = NULL;
    }

Doing CUDA post processing should work fine.
