• Building an android application using ant in eclipse - halfninja /jhotovy ffmpeg for android project

  1er août 2012, par user1545779

  I have successfully built the shared objects in halfninja's android-ffmpeg-x264 git project.
  That project uses ant. Could anyone who has built that project successfully help with the steps he/she used in the second part to build the final apk or
  Could anybody with experience building android applications using ant either as an plugin in Eclipse or as a standalone tool help here
  
  I loaded both the ProjectTest and Project files into Eclipse.

  I am getting the following 2 errors :
  1a. Description : Project "ProjectTest" is missing required Java project "Project"
  I have loaded the Project project already and i can see it
  1b. Location : Build Path
  1c. Type : Build path problem

  2a. The project cannot be built until the build path problem has been resolved
  2b. Location : Unknown
  2c. Type : Java Problem
  
  Please note that I have no clue about editing what file : the available files are : Build.properties and build.xml

  Also how do I install ant into Eclipse and how do i run the application, as an Android, or JavaUnit ..?
  
  Any help will be greatly appreciated

• How to make a videoplayer using FFmpeg on android ndk

  24 juillet 2012, par LMDS

  I'm trying to make a Video Player using ffmpeg and I use this tutorial http://dranger.com/ffmpeg/tutorial08.html, what I understand this tutorial convert a video to a video Image YUV, I'm trying to make the file that interact from .c to .java, I have this

  code c from the tutorial08(http://dranger.com/ffmpeg/tutorial08.c), then I made

  public class RtspReceiver extends Activity

  public SurfaceView sfv;
  
  @Override
  
  public void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.principal);
  
      sfv=(SurfaceView) findViewById(R.id.im);
  
  }
  
  
  
  /* load our native library */
  
  static {
  
      System.loadLibrary("Interface");
  
  }
  
  
  
  private static native void Receive(SurfaceView  sf);

  In the c I'm trying to understand how I can use this

  JNIEXPORT void JNICALL isec_projecto_rtspreceiver_RtspReceiver_Receive(JNIEnv * env, jobject  obj, jobject Surface)
  
  {
  
  //what I have to put in here?
  
  }

  How can I put the SurfaceView that I have in the java, in the c ???
  and other thing, in the tutorial08.c how can I extract the video and put them in the java ? am I thinking correctly ?

• Live transcoding and streaming of MP4 works in Android but fails in Flash player with NetStream.Play.FileStructureInvalid error

  23 juillet 2012, par user831052

  Recently I had a task to use ffmpeg as a transcoding as well a streaming tool. The task was to convert the file from a given format to MP4 and immediately stream it, by capturing it from stdout. So far so good. The streaming works well with the native player of android tabs as well as the VLC player. The issue is with the flash player. It gives the following error :

  NetStream.Play.FileStructureInvalid : Adobe Flash cannot import files that have invalid file structures.

  ffmpeg flags used are

  $ ffmpeg -loglevel quiet -i somefile.avi -vbsf h264_mp4toannexb -vcodec libx264 \
  
  -acodec aac -f MP4 -movflags frag_keyframe+empty_moov -re - 2>&1
