Recording Videos in Chunks Using Media Recorder Android

Question

I am implementing an Application that includes the functionality of saving Recorded Video in to Different Video Files based on a certain amount of Time.

For Achieving that i have implemented a Custom Camera and used the MediaRecorder.stop() and MediaRecorder.start() in a certain Loop.

But this approach is creating a Lag Effect while restarting Media Recorder (Stop and Start). Is it possible to seamlessly Stop and Start Recording using Media Recorder or any Third Party Library ?

Any help is Highly Appreciated.

Answer 1

I believe the best solution to implement chunks recording is to set maximum time in MediaRecorder Object

mMediaRecorder.setMaxDuration(CHUNK_TIME);

then you can attach an info listener, it will intimate you when it will hit maximum chunk time

mMediaRecorder.setOnInfoListener(new MediaRecorder.OnInfoListener() {
  @Override
  public void onInfo(MediaRecorder mr, int what, int extra) {
    if (what == MediaRecorder.MEDIA_RECORDER_INFO_MAX_DURATION_REACHED) {
        // restartVideo()
    }
 }
});

in restartVideo you should firstly clear previous MediaRecorder Object and start video again.
