Subject [jira] [Commented] (FLEX-33558) CameraUI slow return to flex application on certain devices
Date Wed, 05 Jun 2013 17:40:20 GMT

    [ https://issues.apache.org/jira/browse/FLEX-33558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13676159#comment-13676159

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:

> 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.
