Problem playing back HLS in an AIR for IOS app

  • November 8, 2011

I have a basic AIR for IOS app that attempts to play back the sample HLS file included with FMS 4.5. The file I am requesting is at "http://10.173.5.150/hls-vod/sample1_1500kbps.f4v.m3u8"

When I request this file directly in the Safari browser on my Ipad 1, it plays back fine as expected. When I request the same file in an AIR for IOS app on the same Ipad I get a NetStream.Play.StreamNotFound Info event and no playback. OSMF Log pasted below.

Any ideas on what could be wrong here?

I must add that the same AIR app deployed to a Glalaxy Tab 10.1 (Android) plays back the HDS streams fine from "http://10.173.5.150/hds-vod/sample1_1500kbps.f4v.f4m"

Thx

    Hi,

    The HLS workflow is supposed to be working for HTML5 video tags, in Apple supported format m3u8. I doubt if this format is supported by AIR (on iOS). Can you please give a try of the same HDS workflow on AIR on iOS too ?

    Thanks for the reply Nikhil.

    I tried playing HDS on AIR on IOS and the OSMF logs indicate it's attempting to playback, but I dont see any video or hear any audio. Log below
