将RTSP流保存到android中的mp4文件

Posted 2021-05-04

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

显示IP摄像机流。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依赖项。 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.
