在android中将RTSP流保存到mp4文件 [英] Save a RTSP stream to mp4 file in android

问题描述

我正在做一个项目，我需要从 IPCamera 读取输入流.我可以通过 rtsp url 获取它.

I am working on a project where I need to read input stream from an IPCamera. I am able to fetch this in through an rtsp url.

显示 IPCamera 流.我可以通过使用 -

Display the IPCamera stream. I am able to do same by using -

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

现在我想将此流录制到 MP4 文件中.同样，我正在使用 mediarecorder.我被卡住了.

Now I want to record this stream to an MP4 file. For same I am using mediarecorder.Here I am stuck.

    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

推荐答案

使用ffmpeg.

1. 添加 ffmpeg 依赖项.

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

记录流.

Record Stream.

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.
