1. Native console app for video playback in Android

I spent some time for writing a native C++  app to test video in console, actually it seems to be much easier than I thought:) Below is the code snippet:

PS. I thought I should paint a hole above video surface as SurfaceView does, but it appears not necessary.

int main(int argc, char** argv)
{
   LOGI("entering main...");
   sp<ProcessState> proc = ProcessState::self();
   proc->startThreadPool();
   MediaPlayer mediaplayer;
   if(argc > 1)
   {
       LOGI("set datasource: %s", argv[1]);
       mediaplayer.setDataSource(argv[1]);
   }
   else
   {
       LOGI("set datasource: /data/test.mp4");
       mediaplayer.setDataSource("/data/test.mp4");
   }

   LOGI("create SurfaceComposerClient");
   int pid = getpid();
   int nState = 0;
   sp<SurfaceComposerClient> videoClient = new SurfaceComposerClient;

   LOGI("create video surface");
   sp<surface> videoSurface(videoClient->createSurface(pid, 0, 176, 144, PIXEL_FORMAT_OPAQUE, ISurfaceComposer::eFXSurfaceNormal|ISurfaceComposer::ePushBuffers));
   videoClient->openTransaction();
   //nState = videoSurface->setSize(176, 144);
   //LOGI("videosurface->setSize, %d", nState);
   //nState = videoSurface->setPosition(0, 0);
   //LOGI("videosurface->setPosition, %d", nState);

   //set toppest z-order
   nState = videoSurface->setLayer(INT_MAX);
   LOGI("videosurface->setLayer, %d", nState);
   nState = videoSurface->show();
   LOGI("videosurface->show, %d", nState);
   videoClient->closeTransaction();

   LOGI("set video surface to player");
   mediaplayer.setVideoSurface(videoSurface);

   status_t retCode = mediaplayer.prepare();
   if(retCode < 0)
   {
       LOGE("prepare failed: %d\n", retCode);
       IPCThreadState::self()->stopProcess();
       return -1;
   };

   mediaplayer.start();
   for(int i=0; i < 10; i++)
   {
       sleep(1);
       LOGI("playing, i=%d\n", i);
   }
   mediaplayer.reset();
   LOGI("quiting...");

   //close binder fd, still need waiting for all binder threads exit?
   IPCThreadState::self()->stopProcess();
   return 0;
}
