FFmpeg can not open video file after adding the GLsurfaceView to render frames
4 avril 2016, par Kyle LoThe source code works perfectly without any modification.
I successfully use the below function to play the specified video.
playview.openVideoFile("/sdcard/Test/mv.mp4");And for the research purpose I need to display the frame by using OpenGL ES. So I remove the original method below.
ANativeWindow* window = ANativeWindow_fromSurface(env, javaSurface);
ANativeWindow_Buffer buffer;
if (ANativeWindow_lock(window, &buffer, NULL) == 0) {
memcpy(buffer.bits, pixels, w * h * 2);
ANativeWindow_unlockAndPost(window);
}
ANativeWindow_release(window);And I add FrameRenderer class into my project
public class FrameRenderer implements GLSurfaceView.Renderer {
public long time = 0;
public short framerate = 0;
public long fpsTime = 0;
public long frameTime = 0;
public float avgFPS = 0;
private PlayNative mNative = null;
@Override
public void onSurfaceCreated(GL10 gl, EGLConfig config) {/*do nothing*/}
@Override
public void onSurfaceChanged(GL10 gl, int width, int height) {
}
@Override
public void onDrawFrame(GL10 gl) {
mNative.render();
}In the native side I create a corresponding method in VideoPlay.cpp And I only use
glClearColorto test if the OpenGL function works or not.void VideoPlay::render() {
glClearColor(1.0f, 0.0f, 0.0f, 1.0f);
glClear(GL_COLOR_BUFFER_BIT);
}And the
onCreateis as below.protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
playview = new PlayView(this);
playview.openVideoFile("/sdcard/test_tt_racing.mp4");
//playview.openVideoFile("/sdcard/big_buck_bunny.mp4");
GLSurfaceView surface = (GLSurfaceView)findViewById(R.id.surfaceviewclass);
surface.setRenderer(new FrameRenderer());
...Then test it on the mobile, the screen becomes red which means the GLSurfaceView and OpenGL works fine.
But after I press the play bottom, whole the app stucked. And Show in the
LogMy question is why I can open the video whose path is totally the same with the previous one, just after I added the GLsurface renderer and how can I fix it ?
