assuming your web root is at /var/www.
During or after HLS creation, you can watch it on your iOS device. For example, browse the link:
http://IPADDRESS/hls/playlist.m3u8
where IPADDRESS is the IP address of your web server.
If you want to have multiple bitrates, you can use the transcode command instead of the pullStream command to create input streams for HLS creation at different bitrates. Please refer to the transcode command in the EMS API Definition and EMS User Guide: https://evostream.com/support/documentation/
