Hi, Guys:
I have a question about the eglCreateWindowSurface usage. I want to
setup a EGL environment onto the movie view, set by the calling
MediaPlayer::setVideoSurface(xxx) from Java. Then use OpenGL to do the
video output work.
I have refer to some demo code about the setup steps as below:
582 ///////////////////////////////////
583 EGLint configAttribs[] = {
584 EGL_SURFACE_TYPE, EGL_WINDOW_BIT,
585 EGL_NONE
586 };
587
588 EGLint majorVersion;
589 EGLint minorVersion;
590 EGLContext context;
591 EGLConfig config;
592 EGLint numConfigs=0;
593 EGLSurface surface;
594 EGLint w, h;
595 EGLDisplay dpy;
596
597 dpy = eglGetDisplay(EGL_DEFAULT_DISPLAY);
598 eglInitialize(dpy, 0 ,0) ;//&majorVersion, &minorVersion);
599 eglChooseConfig(dpy, configAttribs, &config, 1, &numConfigs);
600
601 ANativeWindow* pW = (ANativeWindow*)(m_pSurfaceHolder-
>m_pSurface);
602 surface = eglCreateWindowSurface(dpy, config,
(EGLNativeWindowType)(pW), NULL);
603 if (surface != EGL_NO_SURFACE)
604 {
605 LOGI("EGL Surface create successfully");
611 }
612 LOGI("EGL surface %x", surface);
613 ///////////////////////////////////
However, I always got a result EGL_NO_SURFACE, and a error log like
this:
E/Surface ( 1393): invalid token (identity=0)
I guess it is because the video surface passed from UI is not proper
to setup EGL environment. So my question is:
What kind of window does eglCreateWindowSurface expect? Should it be
the same with the movie view set from UI, or should I create a new
surface?
Thank you for your reply.
