Adobe Flash Media Live Encoder 3 - IPHONE support, current status

To confirm, currently, FMLEv3:

  • can encode h264 baseline

  • can only encode mp3 audio

To be IPHONE compatible, the stream must be h264 baseline + aac audio.

So one would have to download the Mainconcept AAC encoder plugin for FMLE here:

However in another post this was mentioned by Charlie:

There is currently an AAC timecode issue with this encoder that causes a lip sync drift over time. We are current working on this issue and will report back when we have a fix for it

Is this still an issue?

Does Wowza staff know if Adobe has an update on the way that will include AAC support and any other items necessary for IPHONE broadcast? Do you know what their approx. ETA is?

To my knowledge, other than VLC, there are no other free Windows encoders available capable of produce a IPHONE compliant stream.

Good info. Thanks, Charlie

As far as I know, this issue is not resolved yet.

Wirecast is not free, but it’s not very expensive either, and it works better for this purpose, and has some other nice bells and whistles too.

I all seems to work fine with version 2 FLME

I had a few discussions with MainConcept about this particular bug, and it seems to only happen on certain hardware. In my case, I get the lip sync drift when I run it on my NewTek VT5 rig - but when I take A/V output from the VT5 and pipe it into another machine with an Osprey 210 capture card, FMLE3/MainConcept works just fine for iPhone streaming. I hate going out to analog and back to digital, but it works for now, and on an iPhone-sized screen, it’s not much of an issue.

I’ve been successful with Osprey and Decklink.

I’ve specifically used the Osprey 210 (PCI) and the 230e with FMLE. I’ve also used the 450e. As for DeckLink, I’ve used the Studio HD.

I haven’t specifically used any of the canopus gear, but I know people who have, but on the higher end (like the ADVC-1000).

Advantage of the canopus and decklink gear is that if you decide later on that FMLE isn’t doing it for you, Kulabyte supports DV, Decklink, and Aja hardware.

Just to note wirecast does require a graphics card and direct 3d acceleration, it’s not really the type of encoder you could run on a server but if you’re happy with using it on a workstation I’ve heard good things.

I had a chance to try Wowza on EC2 with FMLE v3.2 without any plugins (h264/mp3) and Intensity Pro during a live event. It worked very well on our website, my iPhone and on the iPad using the JWPlayer v5.5 with html5 support. We were all very pleased.

I must say that I stumbled across this because Wirecast 4 had a glitch in the audio that I didn’t have time to fix so I quickly started up FMLE v3.2 and to my surprise it worked on the iPad and the iPhone with h264/mp3 audio.

I hope to get Wirecast 4 fixed soon because it is much more flexible and it already has the AAC audio codec I need.

We have created a workaround for FMLE+Mainconcept AAC audio syncing issue, but it is not suitable for a long term streaming ( 24+ hours or so ) .

Because FMLE version 2 did not worked for us and it does not have multiple audiences .

Hi guys,

Is there anything new about this problem? We also have audio sync problems with the combination of FMLE 3.1 - h264 + AAC Mainconcept 1.0.5. Even on our Flash player we have audio sync, not only on the iPhone.

Currently we are using one capture card from Pinnacle to send the video to FMLE. I was reading a lot in the forum and sow that the problem must be in the capture hardware that we have.

So my question is this: What is the best hardware device before FMLE ? We are doing analog video and I was wondering to buy canopus advc 110 to send the video by Firewire to FMLE ? I see also some recommendations for Decklink cards and Osprey cards, but witch models exactly can do the job ?

Thank you in advance :slight_smile:

Thank you for quick replay ianbeyer,

So till now I found that the best think to do, when you have audio sync for iPhone or anything (when u set up h264 and AAC of course for FMLE 3.1) is to use hardware witch is known for not having this problem ?

I am doubting now between canopus advc 110, Intensity Pro of Decklink and some of the models of Osprey (dont know witch model).

As I know canopus advc 110 is only making the analog composite or S-video to DV Firewire out, so maybe this is the best for FMLE ? because the others are capture cards and maybe have some issues ? Wondering what is the right combination of hardware to solve the streaming to iPhone .

Hi guys

Is there someone who can tell something new about this problem and share some experience ?
