StageVideo for IOS

After a lot of searching I've got StageVideo working in my IOS app.

See the tutorial posted here: http://01am.co.uk/comment/2

However, I get no audio. The mp4 file itself contains audio (when played in Quicktime) but is silent when played in my IOS app.

Is there something I need to do to activate StageVideo's sound? Has anyone else had similar issues?

What are your encoding settings?

Upload the mp4 to a webserver somewhere and access it via your devices web browser, see if anything changes. Also make sure your devices volume isn't muted or low

Update:

The same issue exists whether the video is packaged with the app, or is downloaded from a server.

For the encoding settings, I've tried Apple TV, Apple iPad, VimeoHD, and every variation the Adobe Media Encoder has.

The video works consistently with all settings, but the audio never works. I've tried this with several mp4 files, all of which work when played in the iPad's browser.

This seems to be an issue with StageVideo itself.

I always use AAC for mp4 audio and it works just fine. Can you go into your audio settings and post the settings you have selected? Also are you exporting 48khz or 44khz?

Do you perhaps have a link to this video you can post here or share in private message? I can get the audio settings from the video and look them over.

I assure you there's lots of mp4 h264 support on iOS and I've actually never seen a mp4 iOS couldn't play perfectly so I'm curious.

I also have pro tools (non-Adobe products) that I use to encode my mp4s. I could encode your video for you if it's not too big. I can tell you the settings used to produce it as well. I use other tools to encode because of the lack of scene change auto-keyframing in adobe media encoder. It's a good all around encoder but it doesn't get files as small as a pro encoder can.

On a last note if you are linking to the video via a web browser, that isn't StageVideo. It's similar in that it's GPU rendered but it's a little different in implementation.
