• FFMPEG RTMP Streaming to Android　Exec

  4 octobre 2012, par user1653922

  I have done in Android using FFMPEG RTMP streaming

  As a practical matter, an error is output when the RTMP streaming with Android.

  "rtmp :/ / ~ / oflaDemo / test live = 1": No such file or directory

  Command execution in Android is as follows.

  String [] command = new String [] {"/ directory / ffmpeg", "-vn", "-re", "-i", "\" rtmp :/ / ~ / oflaDemo / test live = 1 \ "" , "-loglevel", "debug", "pipe: 1"};
  
  Process process = Runtime.getRuntime () exec (command, null);

  Successfully decoded the above command on a FFMPEG on Windows.

  I would like you to tell me if it is good How can Android Can I run the above command.

• 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

• 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 ?
