Calling the interface eglCreateWindowSurface fails during the OpenGL EGL drawing process. It is suspected that Qt also uses the QWidget window handle associated with OpenGL internally, causing the external program to fail to call the egl interface.

How to properly pass the QWidget window handle externally and call the OpengGL EGL drawing process successfully?

To use the attached project:
1. Put the 4 so files in lib into the folder

build-PlayLocalVideo-Android_Qt_6_7_0_Clang_armeabi_v7a-Debug\android-build\libs\armeabi-v7a

2. test.mp4 is a test video, corresponding code

QString strFile = "/storage/emulated/0/test.mp4";,

modify the path by yourself during testing

Error logs printed out from project when playing a local video file:

E libEGL : eglCreateWindowSurface: native_window_api_connect (win=0xb4ebf808) failed (0xffffffea) (already connected to another API?)
E libEGL : eglCreateWindowSurface:516 error 3003 (EGL_BAD_ALLOC)
