Justin Mclean updated FLEX-34437:
---------------------------------
Labels: easytest flex osmf video videodisplay (was: flex osmf video
videodisplay)
> Underlying Components of Spark:VideoDisplay control enter invalid state after
> losing focus
> ------------------------------------------------------------------------------------------
>
> Key: FLEX-34437
> URL: https://issues.apache.org/jira/browse/FLEX-34437
> Project: Apache Flex
> Issue Type: Bug
> Components: Spark: VideoPlayer
> Affects Versions: Apache Flex 4.12.0, Apache Flex 4.13.0, Apache Flex
> 4.12.1
> Environment: Windows 8.1 x64 8GB I7 IntelliJ, Flex 4.12.1
> Mac OS X 10.9, 4GB I5 Intellij Flex 4.12.1
> Reporter: Quinn Buchanan
> Labels: easytest, flex, osmf, video, videodisplay
>
> When using the spark:VideoDisplay control in Flex versions above 12.0, with
> stage video fix applied:
> OSMFSettings.enableStageVideo = false;
> an error is received once the video player is minimized, hidden, or loses
> focus for a period of time. It appears that one of the components enters and
> invalid state ( OSMF?) and reports a state of loading / buffering even though
> video is finished. When cleanup is run or new source added the error listed
> below occurs. Workaround is to manually clear the video when the screen is
> hidden / transitions - code snippet provided below that may help.
> Error / Exception Received:
> TypeError: Error #1009: Cannot access a property or method of a null object
> reference.
