javacv ts files has biger size than ffmpeg cli

when i use ffmpeg to convert from mp4 to hls use this line ffmpeg -i input.mp4 -strict experimental -profile:v baseline -level 3.0 -start_number 0 -hls_time 10 -hls_list_size 0 -f hls index.m3u8 when i test it with 8mb file it give me 7.7 ts files compared to 11 mb ts files generated by javacv using this function

public static void doConversions(File videoFile) {

FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber(videoFile);

try {
    String name = videoFile.getName().split("\\.")[0];
    File file = new File(Paths.get(videoFile.getParentFile().getPath(), name).toString());
    file.mkdir();
    frameGrabber.start();
    Frame grab;
    FrameRecorder recorder = new FFmpegFrameRecorder(new File(file.getPath() + "/" + name + "index" + ".m3u8"), frameGrabber.getImageWidth(), frameGrabber.getImageHeight(), frameGrabber.getAudioChannels());
    recorder.setAspectRatio(frameGrabber.getAspectRatio());
    recorder.setFrameRate(frameGrabber.getFrameRate());
    recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
    recorder.setAudioCodec(avcodec.AV_CODEC_ID_AAC);
    recorder.setOption("vf", "setdar=16:9");
    recorder.setOption("hls_time", "3");
    recorder.setOption("start_number", "0");
    recorder.setOption("hls_list_size", "0");
    recorder.setOption("f", "hls");
    recorder.setOption("level", "3.0");
    recorder.setOption("profile:v", "baseline");
    recorder.setOption("strict", "experimental");
    recorder.start();
    while ((grab = frameGrabber.grab()) != null) {
        recorder.record(grab);
    }
    recorder.stop();
    recorder.release();
    frameGrabber.stop();
} catch (FrameGrabber.Exception | FrameRecorder.Exception ignored) {
    System.out.println(ignored.getMessage());
}}

i don't know why i'm got this result size can someone help me what is wrong with my code
