Issue implementing HLS (http live streaming) with FMS and Flex 4.7

Question

I am facing an issue implementing HLS with FMS 4.5 (also tried with FMS 5). I am following this article http://help.adobe.com/en_US/flashmediaserver/devguide/WSd391de4d9c7bd6 09-52e437a812a3725dfa0-8000.html.

When I am publishing live stream to livepkgr application using FMLE (Flash media live encoder). It's all working fine on my ios devices. But When I am publishing using Flex 4.7 code, the sound is not coming and even video is stop playing after some time on ios devices.

Anyone has any idea why is this happening. Any help will be appreciated.

I am adding code to review. (You can create a flex project and on creation_complete event call "windowedapplication1_creationCompleteHandler". And change the FMS_serverIp to reall fms server ip.

You NetStream object most probably was eat by garbage collector. Try to declare it as field. And same for Camera.
