I have created a media player which plays video on the surface view. After completion of video the last frame of the video remains on the surface. I want to remove the video frame from the surface because after some delay another video starts.
The flow of the video is:
NOW: Video on surface -> last video frame on surface -> another video on surface.
But the required flow is:
REQUIRED: Video on surface -> clear surface (black) -> another video on surface.
can anyone help to solve this problem.
Thanks Ishan jain
Building on Fadden's answer, and Andreimarinescu's question, here is a version for API 16 and below:
private void clearSurface(Surface surface) {
EGL10 egl = (EGL10) EGLContext.getEGL();
EGLDisplay display = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY);
egl.eglInitialize(display, null);
int[] attribList = {
EGL10.EGL_RED_SIZE, 8,
EGL10.EGL_GREEN_SIZE, 8,
EGL10.EGL_BLUE_SIZE, 8,
EGL10.EGL_ALPHA_SIZE, 8,
EGL10.EGL_RENDERABLE_TYPE, EGL14.EGL_OPENGL_ES2_BIT,
EGL10.EGL_NONE, 0, // placeholder for recordable [@-3]
EGL10.EGL_NONE
};
EGLConfig[] configs = new EGLConfig[1];
int[] numConfigs = new int[1];
egl.eglChooseConfig(display, attribList, configs, configs.length, numConfigs);
EGLConfig config = configs[0];
EGLContext context = egl.eglCreateContext(display, config, EGL10.EGL_NO_CONTEXT, new int[]{
EGL14.EGL_CONTEXT_CLIENT_VERSION, 2,
EGL10.EGL_NONE
});
EGLSurface eglSurface = egl.eglCreateWindowSurface(display, config, surface,
new int[]{
EGL14.EGL_NONE
});
egl.eglMakeCurrent(display, eglSurface, eglSurface, context);
GLES20.glClearColor(0, 0, 0, 1);
GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT);
egl.eglSwapBuffers(display, eglSurface);
egl.eglDestroySurface(display, eglSurface);
egl.eglMakeCurrent(display, EGL10.EGL_NO_SURFACE, EGL10.EGL_NO_SURFACE,
EGL10.EGL_NO_CONTEXT);
egl.eglDestroyContext(display, context);
egl.eglTerminate(display);
}
Pretty crude, lacks error checking, but it works for me.
