Sample RecordActivity.java seems isn't practical at all - java very high memory usage

https://github.com/bytedeco/javacv/blob/master/samples/RecordActivity.java

I'm not sure about this part of code (as practical solution):

private void initRecorder() {

        Log.w(LOG_TAG,"init recorder");

        if (RECORD_LENGTH > 0) {
            imagesIndex = 0;
            images = new Frame[RECORD_LENGTH * frameRate];
            timestamps = new long[images.length];
            for (int i = 0; i < images.length; i++) {
                Log.i(LOG_TAG, "Allocating buffer for new Frame " + i);
                images[i] = new Frame(imageWidth, imageHeight, Frame.DEPTH_UBYTE, 2);
                timestamps[i] = -1;
            }
        } else if (yuvImage == null) {
            yuvImage = new Frame(imageWidth, imageHeight, Frame.DEPTH_UBYTE, 2);
            Log.i(LOG_TAG, "create yuvImage");
        }

        Log.i(LOG_TAG, "ffmpeg_url: " + ffmpeg_link);
        recorder = new FFmpegFrameRecorder(ffmpeg_link, imageWidth, imageHeight, 1);
        recorder.setFormat("mp4");
        recorder.setSampleRate(sampleAudioRateInHz);
        // Set in the surface changed method
        recorder.setFrameRate(frameRate);
        recorder.setVideoCodec(28);
        recorder.setVideoOption("crf", "28");
        recorder.setVideoOption("preset", "superfast");

        Log.i(LOG_TAG, "recorder initialize success");

        audioRecordRunnable = new AudioRecordRunnable();
        audioThread = new Thread(audioRecordRunnable);
        runAudioThread = true;
    }

Example sets small image size:

private int imageWidth = 320;
private int imageHeight = 240;

yeah, it would work ok.

when I set 640x480, java memory allocating is pretty big:

on my phone max java heap == ~200

when I set hd (1280x720) it would fail to record almost at start:

so it just allocates too much java memory (it won't be able to record in hd quality or full hd)

In my projects I use this example of javacv ffmpeg recording for Android https://github.com/CrazyOrr/FFmpegRecorder (java ffmpegrecorder class: https://github.com/CrazyOrr/FFmpegRecorder/blob/master/app/src/main/java/com/github/crazyorr/ffmpegrecorder/FFmpegRecordActivity.java)

Earlier this example also had mem issues, but author made some fixes: https://github.com/CrazyOrr/FFmpegRecorder/issues/15#issuecomment-274314329 (and I don't notice any quality suffering when recording hd size)

so it doesn't have problems with high java memory usage, I can record in hd or even in full hd quality without problems

though it does quite use many cpu (~25-50%) and doesn't matter which quality I set (crf, image resolution, framerate)

RecordActivity.java sample seems doesn't load cpu at all, but eats many java memory and won't be able to record with size like hd
