Is there other api as eglQueryStreamKHR?

hi
is there other api as eglQueryStreamKHR to show the status of eglstream?
i am work without EGLDisplay.
if the first param in eglQueryStreamKHR was EGL_NO_DISPLAY,it will crash。

Hi,
Could you try EGL_DEFAULT_DISPLAY?

There is a topic about headless mode and may be similar to your case:

In headless mode, you would need to keep nvdisplay driver or certain functions may not work properly.
