• FFMPEG set -ss and -to with string

  12 mai 2017, par NewUser

  I know I can set the start with -ss and end with -to but can someone please help me to format the following so that I can enter the -ss and -to with a string ?

  I want -ss to come from

  String start = editStart.getText().toString();

  and -to to come from

  String end = editEnd.getText().toString();

  Here is my ffmpeg string I want to edit, I have entered -ss and -to to show where I want the above strings to be.

  String s = "-i" + " " + mVideoUri.toString().replace("file:///", "") + " -i " + newBackgroundBitmap.getPath() +  " -filter_complex [1:v][0:v]scale2ref=iw:ih[ovr][base];[ovr]colorchannelmixer=aa=0.7[ovrl];[base][ovrl]overlay[v] -ss -to -map [v] -c:v libx264 -preset ultrafast " + directoryToStore + "/" + FileName + mp4;
  
  
  
  String[] arguments = s.split(" ");
  
  
  
  ExecuteFFMPEG(arguments);

  EDIT

  Here is the full ffmpeg

  //Button onclick
  
  public void onButtonClicked(View view) {
  
      switch (view.getId()) {
  
  
  
      //WHEN THE EXPORT BUTTON IS CLICKED
  
      case Export:
  
          String s = "-i" + " " + mVideoUri.toString() + " -i " + newBackgroundBitmap.getPath() + " -filter_complex [1:v][0:v]scale2ref=iw:ih[ovr][base];[ovr]colorchannelmixer=aa=0.7[ovrl];[base][ovrl]overlay[v] -map [v] -c:v libx264 -preset ultrafast " + directoryToStore + "/" + lastSaved + mp;
  
          String[] arguments = s.split(" ");
  
          ExecuteFFMPEG(arguments);
  
  
  
      }
  
  }
  
  
  
  //Added onLoad FFMPEG
  
  public void LoadFFMPEG() {
  
  
  
      FFmpeg ffmpeg = FFmpeg.getInstance(getBaseContext());
  
      try {

      } catch (FFmpegNotSupportedException e1) {
  
          e1.printStackTrace();
  
          Log.d("[FFMPEGMain Exception]-", e1.toString());
  
      }
  
  }
  
  
  
  //Added Exceute FFMPEG
  
  public void ExecuteFFMPEG(String[] command) {
  
  
  
  
  
      FFmpeg ffmpeg = FFmpeg.getInstance(getBaseContext());
  
      try {
  
  
  
          ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
  
  
  
              @Override
  
              public void onStart() {
  
                  super.onStart();
  
                  Log.d("[Start]", "start");
  
  
  
              }
  
  
  
              @Override
  
              public void onProgress(String message) {
  
                  Log.d("[Progress]", message);
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
                  Log.d("[fail]", message);
  
              }
  
  
  
              @Override
  
              public void onSuccess(String message) {
  
                  Log.d("[Success]", message);
  
  
  
  
  
              }
  
  
  
  
  
              @Override
  
              public void onFinish() {
  
                  super.onFinish();
  
                  Log.d("[Finish]", "file output done");
  
  
  
              }
  
  
  
          });
  
      } catch (FFmpegCommandAlreadyRunningException e) {
  
          // Handle if FFmpeg is already running
  
          Log.d("[FFMPEG Exception]-", e.toString());
  
  
  
      }
  
  
  
  
  
  }

  The above works perfectly as I was hoping. Now I want to set the start and end of the video (depending on the position the user selected). I get the start and end of the video back as a string, like this :

  String valueRight = formatter.format(getValueRight);
  
  String valueLeft = formatter.format(getValueLeft);
  
  
  
  //this strings will return 00:00:00.000 DEPENDING on the position from the user
  
  //just like when you would normally call -ss 00:00:50.849 -to 00:02:05.100

  As I mentioned above that I know it should be set as -ss and -to but I am looking for a wat to format my string to enter -ss and -to with a string, somthing like this :

  -ss valueLeft -to valueRight

  I am trying following code

  I have used following library for FFmpeg

  dependencies {
  
      compile fileTree(dir: 'libs', include: ['*.jar'])
  
      testCompile 'junit:junit:4.12'
  
      compile 'com.android.support:appcompat-v7:23.1.1'

      compile 'commons-io:commons-io:2.5'
  
  }

  and added following permission in manifest

  the files are present at the path used , but output.mp4 is not created

  the log says

• FFmpeg Video Streaming on android app

  18 avril 2017, par Johnny Roger

  I’m trying to do a streaming of my laptop webcam to my android smartphone.
  So I set an ffserver in this way

  HTTPPort 1234
  
  RTSPPort 1235
  
  
  
  <feed>
  
          File /tmp/feed2.ffm
  
          FileMaxSize 2M
  
          ACL allow 127.0.0.1
  
  </feed>
  
  
  
  <stream>
  
      Feed feed2.ffm
  
      Format rtp
  
      Noaudio
  
      VideoCodec libx264
  
      AVOptionVideo flags +global_header
  
      AVOptionVideo me_range 16
  
      AVOptionVideo qdiff 4
  
      AVOptionVideo qmin 10
  
      AVOptionVideo qmax 51
  
      ACL allow 192.168.0.0 192.168.255.255
  
  </stream>

  and I used the following ffmpeg instruction

  ffmpeg -i /dev/video0 -vcodec libx264 -tune zerolatency -crf 18 http://localhost:1234/feed2.ffm

  in my android studio project i set in the manifest file

  That is my MainActivity.java

  package com.example.johnny.ffmpeg;
  
  
  
  import android.app.ProgressDialog;
  
  import android.content.Context;
  
  import android.media.MediaPlayer;

      ProgressDialog mDialog;
  
      VideoView videoView;
  
      ImageView btnPlayPause;
  
      MediaController mediaController;
  
  
  
      String videoURL ="rtsp://192.168.1.100:1235/test1.sdp";
  
  
  
  
  
      @Override

      @Override
  
      public void onClick(View v) {
  
          mDialog = new ProgressDialog(MainActivity.this);
  
          mDialog.setMessage("Please wait...");
  
          mDialog.setCanceledOnTouchOutside(false);
  
          mDialog.show();
  
  
  
          Uri uri = Uri.parse(videoURL);
  
          videoView.setVideoURI(uri);
  
  
  
          try{
  
              if(!videoView.isPlaying()) {
  
  
  
  
  
                  videoView.setMediaController(mediaController);
  
                  videoView.requestFocus();
  
  
  
                  videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
  
                      @Override
  
                      public void onCompletion(MediaPlayer mp) {
  
                          btnPlayPause.setImageResource(R.drawable.ic_aplay);
  
                      }
  
                  });
  
              }
  
              else
  
              {
  
                  videoView.pause();
  
                  btnPlayPause.setImageResource(R.drawable.ic_pause);
  
              }
  
          }
  
          catch(Exception ex)
  
          {
  
  
  
              Context context = getApplicationContext();
  
              String text = ex.toString();
  
              int duration = Toast.LENGTH_SHORT;
  
  
  
              Toast toast = Toast.makeText(context, text, duration);
  
              toast.show();
  
          }
  
  
  
          videoView.requestFocus();
  
          videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener(){
  
              @Override
  
              public void onPrepared(MediaPlayer mp){
  
                  mDialog.dismiss();
  
                  mp.setLooping(true);
  
  
  
  
  
  
  
                  videoView.start();
  
                  btnPlayPause.setImageResource(R.drawable.ic_pause);
  
              }
  
          });
  
  
  
          videoView.setOnErrorListener(new MediaPlayer.OnErrorListener() {
  
  
  
              @Override
  
              public boolean onError(MediaPlayer mp, int what, int extra) {
  
                  Log.d("video", "setOnErrorListener ");
  
                  return true;
  
              }
  
          });
  
  
  
      }
  
  }

  and that is the relative activity_main.xml file :

  <relativelayout>
  
  
  
       <videoview></videoview>
  
  
  
      
  
  
  
      <textview></textview>
  
  
  
      <textview></textview>
  
  
  
  </relativelayout>

  I tested the streaming on vlc and it work well (even if with dealy, it’s not in real time).
  The app instead give me the message "can’t play this video" and the following error :

  V/MediaPlayer: message received msg=100, ext1=1, ext2=-38
  
  E/MediaPlayer: Error (1,-38)
  
  D/VideoView: Error: 1,-38
  
  D/video: setOnErrorListener 
  
  E/MediaPlayer: error (1, -38)
  
  V/MediaPlayer: callback application
  
  V/MediaPlayer: back from callback
  
  E/MediaPlayer: Error (1,-38)
  
  D/VideoView: Error: 1,-38
  
  D/video: setOnErrorListener 
  
  
  
  E/ViewRootImpl: sendUserActionEvent() mView == null

  I saw that the problem could be the format of the video, but i tried also with an mp4 file

  ffmpeg -i test.mp4 -vcodec libx264 -tune zerolatency -crf 18 http://localhost:1234/feed2.ffm

  and the result was the same. How Can I fix it and let my app work well ?
