Android MediaRecorder Multiple Files
I am using a MediaRecorder to record video from the camera save it as .mp4 to the SDCard, which works flawlessly. I would like to limit the length of the .mp4 files to 10 seconds each and then automatically create a new file (ie: If a user records 30 seconds I would like to create three files, segment1.mp4 (0:00-0:10), segment2.mp4 (0:10-0:20), and segment3.mp4 (0:20-0:30)).
Here is where I set up the recorder and the output. What should I be doing to make this happen while recording?
private boolean prepareVideoRecorder() {
this.mMediaRecorder = new MediaRecorder();
this.mCamera.stopPreview();
this.mCamera.unlock();
this.mMediaRecorder.setCamera(mCamera);
this.mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
this.mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
this.mMediaRecorder.setOrientationHint(90);
this.mMediaRecorder.setMaxDuration(this.VIDEO_CHUNK_LENGTH_MS); //10,000 ms
if (getAndroidSDKVersion() >= 8) {
this.mMediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
} else {
this.mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
this.mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
this.mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
}
this.mVideoFileName = getOutputMediaFile(MEDIA_TYPE_VIDEO).toString(); // Returns a proper file name
this.mMediaRecorder.setOutputFile(mVideoFileName);
this.mMediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());
try {
this.mMediaRecorder.prepare();
} catch (IllegalStateException e) {
Log.d(TAG, "IllegalStateException preparing MediaRecorder: " + e.getMessage());
this.releaseMediaRecorder();
return false;
} catch (IOException e) {
Log.d(TAG, "IOException preparing MediaRecorder: " + e.getMessage());
this.releaseMediaRecorder();
return false;
}
return true;
}
