Video rendering issues when focusing a text component

Evyatar Ben Halevi-Arbib
Hello,

When compiling using Apache Flex 4.13 & AIR 15 for Android tablets we
encountered the following issue -
Focusing in a text component (TextInput or TextArea) located next to the
video causes the displayed video to "jump".

You can see how it looks in this clip -
https://dl.dropboxusercontent.com/u/8740014/2014-09-23%2013.06.04.mov

In addition, it can be easily reproduced using the following sample
application -

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

                        xmlns:s="library://ns.adobe.com/flex/spark"
applicationDPI="160">



       <s:VideoDisplay width="50%" height="400" source="
http://mediapm.edgesuite.net/osmf/content/test/manifest-files/dynamic_Streaming.f4m"
/>



       <s:TextArea top="0" right="0" />



</s:Application>


Thanks in advance,

Evyatar

Can anybody please look at this?

It's a very strange behavior that the video jumps when something happens in
a text component next to it...

Thanks in advance,
Evyatar

I thought that if you run too much ActionScript in any frame it will
affect video.  You might want to profile what is running when the video
skips.

Please check the simple application example.
It contains only one VideoDisplay component and one TextArea component, but
it's enough to reproduce the issue.

Thanks in advance,

Re: Video rendering issues when focusing a text component

A lot of code can run when focusing a Spark TextArea.  I assume you've
tried other components like mx:TextArea or mx:TextInput and they don't
have the same problem?

I know it is an old post, but I also have the same issue with Flex 4.16/AIR 23.0, did you find any solution?
