Problem playing back HLS in an AIR for IOS app

Report · Nov 08, 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

*Bump*

Is there any update on this?

Can someone from the FMS team pls. confirm. whether streaming H264 from FMS to an AIR for IOS app is supposed to work.

If so what protocol are we supposed to use ?

Thanks,

Hi Abey

OSMF can't play HLS out of the box, only Adobe's HDS;

If you want to get HLS playing back in OSMF, extra code is needed.

Matthew Kaufman has a project started for this here: http://code.google.com/p/apple-http-osmf/

However it hasn't been ported to the latest version of OSMF yet, and from what I can tell still needs some dev.

This is really only necessary if you want to play HLS within flash, on non-Apple devices, or in some modified way.

Otherwise it's pretty easy to just use the native Apple players e.g. in a <video> tag.

Cheers

Nick

Thanks for the reply Nick. I will look into the project you referenced.

My higher level objective here is to be able to stream H264 video from FMS into an AIR for IOS app, preferably using OSMF. It doesnt have to be HLS.

Is there any format that you know of that is offically supposed to work in AIR for IOS?

Yep, I would try Adobe's standard for HTTP adaptive streaming, which is called "HTTP Dynamic Streaming" or HDS

To be honest, in my experience it's a little more complex than HLS (e.g. I had problems even with the media packager)

but since it's Adobe you should get better support and workiness ootb .... should ....

It is implemented in OSMF, it seems to work quite well, and you can run that in AIR.

Report · Nov 29, 2011

As I mentioned earlier on in the post, I have not been able to get HDS to work on IOS. The OSMF logs indicate that the stream is playing back, but I hear no audio or video.

The same app streams HDS fine in Android and Windows 7.

Have you been able to get HDS working successfully in AIR for IOS?

Report · Nov 29, 2011

Nope I haven't tried yet.

You know what I just found, is jwplayer with in-flash HLS support:
