Why I can't find symbols EGL_SUPPORT_RESET_NV in eglext.h ?

I can find the symbols EGL_SUPPORT_RESET_NV in the <EGL/eglext.h> for EGL 1.5 at https://www.khronos.org/registry/EGL/. And I want to use it in TX2 with the JetPack3.1, but I can’t find it in the eglext.h file, does it not support this API in TX2.If supported, how can I do that I can use this extension.

This is the API at https://www.khronos.org/registry/EGL/api/EGL/eglext.h :

#ifndef EGL_NV_stream_reset
#define EGL_NV_stream_reset 1
#define EGL_SUPPORT_RESET_NV 0x3334
#define EGL_SUPPORT_REUSE_NV 0x3335
typedef EGLBoolean (EGLAPIENTRYP PFNEGLRESETSTREAMNVPROC) (EGLDisplay dpy, EGLStreamKHR stream);
#ifdef EGL_EGLEXT_PROTOTYPES
EGLAPI EGLBoolean EGLAPIENTRY eglResetStreamNV (EGLDisplay dpy, EGLStreamKHR stream);
#endif
#endif /* EGL_NV_stream_reset */

Hi,

Jetson EGL header is within MMAPI package.
Please install Multimedia API package via JetPack and copy the EGL and GLES2, GLES3, KHR headers from “~/tegra_multimedia_api/include” to “/usr/include”.

Thanks.
