Jesse Hellyer commented on FLEX-33558:
--------------------------------------
How do I know that this is an AIR method? I am using the captive runtime, its
the only option that Flash Builder allows me to do when compiling for iOS.
I wouldn't be using the JPEGEncoder as non-SDK code, but the SDK code causes
NUMEROUS memory leaks and other issues, and its much much much slower than the
one I am using that is non standard. Like 5x slower. I would prefer not to
have to JPEG encode it at all, but I need the data in a format that I can read.
Do you have any suggestions on where I can go from here? Has anyone ever
gotten CameraUI to work correctly for themselves in a release version app?

> I have been having very slow results with the CameraUI in flex. Initially,
> I was using version 3.1 which was VERY buggy, and I was running into erroring
> out returning from the CameraUI, and very slow speeds.
> I have since downloaded and installed the newest Apache Flex framework,
> 4.9.1. The CameraUI returns VERY fast on our Samsung Tab 7.1 that we bought
> a few months ago. On an older Droid Charge phone, that is up to date with
> updates, it takes 30-40 seconds to return from the CameraUI into my code.
> Same with an iPhone 4 running iOS 6.1.
> The line in question is marked in yellow below:
> mpLoader.loadFilePromise(mediaPromise);
> Essentially, I call the cameraUI when the user hits a button. The native
> camera interface opens up right away. A picture is taken. On iOS and
> Android both, you have to “save” or “use” the picture. Once you click that
> button in the native UI, the camera holds on a black screen for a long time
> (up to 30 seconds or so). That’s where the error seems to be,
> mpLoader.loadFilePromise(mediaPromise);
> You can see in the code I have put output statements to a label showing where
> the code is hanging. It hangs right after it writes out -16
> Here is the code:

> And here is the XML config file:
> https://gist.github.com/MrJesse34/5627336
> Here is a video of the behavior on my iPhone:
> http://www.youtube.com/watch?v=_QufH1ElqXo
> the issue starts at :30 and ends around :50
> you can see the busy indicator stops spinning for that time
> Note the delay of the busy indicator - it happens right as the
> mpLoader.loadFilePromise(mediaPromise); code is ran.
