Example 6 with EglCore

use of com.android.grafika.gles.EglCore in project grafika by google.

the class PlayMovieSurfaceActivity method clearSurface.

/**
     * Clears the playback surface to black.
     */
private void clearSurface(Surface surface) {
    // We need to do this with OpenGL ES (*not* Canvas -- the "software render" bits
    // are sticky).  We can't stay connected to the Surface after we're done because
    // that'd prevent the video encoder from attaching.
    //
    // If the Surface is resized to be larger, the new portions will be black, so
    // clearing to something other than black may look weird unless we do the clear
    // post-resize.
    EglCore eglCore = new EglCore();
    WindowSurface win = new WindowSurface(eglCore, surface, false);
    win.makeCurrent();
    GLES20.glClearColor(0, 0, 0, 0);
    GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT);
    win.swapBuffers();
    win.release();
    eglCore.release();
}

Example 7 with EglCore

use of com.android.grafika.gles.EglCore in project grafika by google.

the class TextureMovieEncoder method handleUpdateSharedContext.

/**
     * Tears down the EGL surface and context we've been using to feed the MediaCodec input
     * surface, and replaces it with a new one that shares with the new context.
     * <p>
     * This is useful if the old context we were sharing with went away (maybe a GLSurfaceView
     * that got torn down) and we need to hook up with the new one.
     */
private void handleUpdateSharedContext(EGLContext newSharedContext) {
    Log.d(TAG, "handleUpdatedSharedContext " + newSharedContext);
    // Release the EGLSurface and EGLContext.
