将RTSP流保存到android中的mp4文件

Question

我正在开发一个项目,我需要从IPCamera中读取输入流.我可以通过rtsp url获取此信息.

显示IPCamera流.我可以通过使用 -

    videoView = (VideoView) this.findViewById(R.id.videoView1);
    MediaController mc = new MediaController(this);
    videoView.setMediaController(mc);
    videoView.setVideoURI(Uri.parse("rtsp://xxxxxxxx/camera1"));
    videoView.requestFocus();

现在我想将此流记录到MP4文件中.同样我使用mediarecorder.Here我被卡住了.

    MediaRecorder mediaRecorder = new MediaRecorder();
    //mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
    mediaRecorder.setOutputFile("rtsp://xxxxxxxxx/camera1");
    try {
        mediaRecorder.prepare();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    mediaRecorder.start();

谢谢

使用ffmpeg。

1. 添加ffmpeg依赖。

   compile 'nl.bravobit:android-ffmpeg:1.1.5'
   

2. 记录流。

   String RTSP_URL = "rtsp://<your_rtsp_url>";
   
   final File targetFile = new File( getExternalStoragePublicDirectory( Environment.DIRECTORY_MOVIES )  + "/recording1.mp4" );
   
   final FFmpeg ffmpeg = FFmpeg.getInstance(this);
   
   String[] ffmpegCommand = new String[]{  "-i", RTSP_URL, "-acodec", "copy", "-vcodec", "copy", targetFile.toString() };
   
   final FFtask ffTask = ffmpeg.execute( ffmpegCommand, new FFcommandExecuteResponseHandler() {
   
     @Override
     public void onStart() {}
   
     @Override
     public void onProgress(String message) {}
   
     @Override
     public void onFailure(String message) {}
   
     @Override
     public void onSuccess(String message) {}
   
     @Override
     public void onFinish() {}
   
   } );
   
   final Timer timer = new java.util.Timer();
   
   TimerTask timerTask = new TimerTask() { @Override public void run() {
     ffTask.sendQuitSignal();
   } };
   
   timer.schedule( timerTask, 30000 ); // Will stop recording after 30 seconds.
