Apple has announced their own http live streaming protocol, based on http and mpegts.

Apple advise you to use file based segmenter, which will raise disk usage almost 2,3 times. Erlyvideo can stream H.264 files to iPhone without any intermediate files, creating segments on fly.

You should provide following playlist url for video source:

http://erlyvideo-ip:8082/iphone/playlists/{file_path}.m3u8

For example, it may be:

http://erlyvideo-up:8082/iphone/playlists/video.mp4.m3u8

You can do iPhone streaming without erlyvideo, but you will have to work with many segment files, crushing your hard drive.

Erlyvideo can stream your multibitrate files without tonns of segments.
