I am trying to generate and play a HLS stream in HEVC codec using bento4's `mp4hls` command. The issue is that when I upload the stream on S3, it is not playing on Safari (Note: stream is not working/playing from local as well).

Since HEVC has added benefits, I prefer keeping the codec to h265 only. 

Another point to note here is that I manually converted the `mp4` file from `h264` to `h265`. If there's a way to achieve the above config without generating an intermediate h265 mp4, I'll be happy to use that as well.

Command used:
```
mp4hls original.mp4 --hls-version=7 --master-playlist=playlist --media-playlist-name=temp
```

ffprobe of the file is
