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; }
