how can reduce video size at time of recording, Android?

ffmpeg , mediacodec , and mp4parser codecs are taking time to compress, so is there any other way to reduce size of video at time of recording?

I am using MediaRecorder for recording videos but it creates a lot of data, and I want to reduce it as I'm not able to upload it.

I got my answer with the use of media Recording Documentation and added this lines in code:

mediaRecorder.setVideoEncodingBitRate(1000000);
mediaRecorder.setVideoSize(1280, 720);
mediaRecorder.setOutputFile(folder.getAbsolutePath()+"/"+mediaFileName+".mp4");
mediaRecorder.setPreviewDisplay(surfaceHolder.getSurface());
mediaRecorder.setVideoFrameRate(18);
mediaRecorder.setOrientationHint(mOrientation);

After this, I get a lower size of video with good quality.
