First thing @Chan Woo Jeong is to make sure you are using codecs we support in your mp4 container:
Wowza Streaming Engine media server software only supports H.264 (AVC1, MPEG-4 Part 10), AAC (MP4A, AAC, AAC+, HE-AAC), and MP3 in an MP4 file.
Then follow this guide here to set it up:

Now you can adjust your settings for HLS playback:

The chunk size, the number of chunks required and a few other settings in the article above will help you avoid it playing too slowly.
