I have a sample but will need to dig it out.

In general there are a couple things you need to do.

First is OSMF 1.6 did not have it enabled, you need something after 1.6 release.

Also in your app descriptor you need to set the render mode to "direct".

Aside from that you need to make sure all the normal StageVideo requirements are set for you compiling.

Hi David,

Thanks for the reply. I would really appreciate it if you could dig out the sample.

I am using OSMF 1.6.1, AIR 3.1, Flex 4.6 and FMS 4.5. From my tests so far it does not seem like its possible to stream H264 from FMS to AIR for IOS. Not just HLS, any kind of H264 streaming does not seem to work.

If I switch to using progressive download, that seems to work. Below is the matrix I have arrived at from my tests. Would love to be proven wrong on this one.

FMS 4.5 H.264 Streaming test matrix
	RTMP	HDS	HLS	HTTP Progressive Download
AIR for Android	Yes	Yes	No	Yes

AIR on Windows (Desktop)	Yes	Yes	No	Yes

AIR on IOS	No	No	No	Yes

Safari Browser on IOS	No	No	Yes	No

I wrote an extremely simple AIR app for mobile that is basically a list of videos, if you touch/select one it will play it.

I was able to stream h264 dynamic streams via rtmp no problem, and the app ran fine on both a Nexus One Android phone and a first generation iPad running iOS v4.something (whatever the minimum was to run AIR, I believe).

EDIT: I even have a video of it! http://www.youtube.com/watch?v=1xImrP_ljq8

Cheers,

mark

@Mark,

Thanks for the reply. Hmm thats interestting. Would you be able to share the app-config so I can look at the settings.?

I just cant seem to be able to play H264 videos. VP6 based FLV files stream fine , but not H264.

Thanks

Thanks to everyone who replied.

The conclusiver answer is that there are only 2 ways to display H264 video in AIR for IOS

(more info here http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/fla sh/net/NetStream.html#play%28%29)

1. Progressive download

2. HLS format (slight caveat, in my tests at least, OSMF 1.6.1 does'nt handle this, but if you use the NetStream directly with StageVideo enabled it works)

Updated Matrix is :

FMS 4.5 H.264 Streaming test matrix
	RTMP	HDS	HLS	HTTP Progressive Download
AIR for Android	Yes	Yes	No	Yes

AIR on Windows (Desktop)	Yes	Yes	No	Yes

AIR on IOS	No	No	Yes	Yes

Safari Browser on IOS	No	No	Yes	No

just to be clear. to support H.264 (progessive or HLS) for AIR for iOS the following conditions must be met.

AIR 3.0 or later

iOS 4 (5 in the future hopefully - issues at the moment)

renderMode must be set to "direct" in the app descriptor.

OSMF 1.6.1 or an ActionScript equivalent that requires the use of StageVideo

@David :As I mentioned before. I have not been able to get HLS working with OSMF 1.6.1 in AIR on IOS. It only seems to work when I use NetStream directly.

Do you have any code sample that proves otherwise?

Are you saying StageVideo works in iOS or this is just some sort of hack?

AFAIK StageVideo does not work in Adobe Air, desktop or ios.

I am saying that StageVideo works on the IOS device. (at least the IPad 2, which is what I used to test)

You are right, I just saw it in the documentation. The only Air application with no StageVideo is the desktop (sadly).

So I'm running into trouble adding a .mp4 H.264 file to my Flash CS5.5 project as part of the air applicationDirectory, and the iPad not being able to play the video. Can it not play back locally stored files? OSMF will happily play back a .flv file, but I can't get .mp4 format in 264 to play back on the native devices for the life of me.

Suggestions?

Are you using StageVideo? it is required. I know progressive H.264 with stage video works as well as HLS, and I assume local should be fine as long as you resolve the path properly.

Well, I assume I am. I have everything set up for 3.1 and set up a working StageVideo example to work with my android table. The iPad chokes on the same code.

Any easy way to get trace output of if iOS is actively using StageVideo?
