下载rtsp流以在本地播放

Question

I manage to play a live stream from a url such as this

rtsp://192.168.0.18:554/user=admin&password=&channel=1&stream=0.sdp?

But I want to download this stream into a temporary file and then play it locally so that I can make it seems like the buffering time is short (around 2-4 seconds delay maybe)

Is it possible to do this with rtsp ? or do I have to use http ?Because this url only works on rtsp protocol

If so,a bit of example would help me alot

Example of my codes

cA.mPlayer1 = new MediaPlayer();
  try {
    cA.mPlayer1.setDataSource("rtsp://192.168.0.18:554/user=admin&password=&channel=1&stream=0.sdp?");
    cA.mPlayer1.prepareAsync();
    cA.mPlayer1.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
      @Override
      public void onPrepared(MediaPlayer mediaPlayer) {
        cA.mPlayer1.start();
        Toast.makeText(getBaseContext(), "Connecting...", Toast.LENGTH_LONG).show();
      }
    });
  } catch (IOException e) {
    e.printStackTrace();
  }
  cA.mCallback1 = new SurfaceHolder.Callback() {
    @Override
    public void surfaceCreated(SurfaceHolder surfaceHolder) {

      cA.mPlayer1.setDisplay(surfaceHolder);

    }
    @Override
    public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i2, int i3) {
    }
    @Override
    public void surfaceDestroyed(SurfaceHolder surfaceHolder) {
    }
  };

final SurfaceView surfaceView1 =
        (SurfaceView) findViewById(R.id.surfaceView1);
// Configure the Surface View.
surfaceView1.setKeepScreenOn(true);
// Configure the Surface Holder and register the callback.
SurfaceHolder holder1 = surfaceView1.getHolder();
holder1.addCallback(cA.mCallback1);
holder1.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

you can not use MediaPlayer to save a Raw stream in file . you can use one of these :

• use 'vlc' to save the stream like this: https://wiki.videolan.org/Documentation:Streaming_HowTo/Receive_and_Save_a_Stream/

  or use 'VLC lib' for android that can downloaded from : https://github.com/mrmaffen/vlc-android-sdk

• use FFMPEG library to record RTSP recording locally in sd card :

1- Capture or decode the RAW frames from live stream and pass them to ffmpeg and save them to sdcard in .h264 format.

2- Then again pick .h264 raw file and decode the file using ffmpeg, and save the file with extention .mp4 into sd card.

3- delete the .h264 file programmatically, and save only .mp4, or which format you want. Try .mp4 playback.
