Only happens on 4.16.1. Works w/o problem on 4.6.
> Spark VideoDisplay error
> ------------------------
>
> Key: FLEX-35398
> URL: https://issues.apache.org/jira/browse/FLEX-35398
> Project: Apache Flex
> Issue Type: Bug
> Components: Spark: VideoPlayer
> Affects Versions: Apache Flex 4.16.1
> Reporter: SteveJC
> Priority: Major
>
> App I'm maintaining was originally develop using Adobe Flex 4.6. I have tried
> compiling it under Apache Flex 4.16.1 and AIR SDK 32.
> Btw I encountered problem with the ant installer but got past it by removing
> references to the errant "air-check" task. After that, AIR SDK downloads the
> correct version fine.
> On to the main problem:
> I'm using VideoDisplay (spark) somewhere in my code and it was throwing this
> error:
> {code:java}
> RangeError: Error #2004: One of the parameters is invalid.

> There seems to be a bug in the OSMF code(?).
> The workaround I did was to simply switch back to mx:VideoDisplay and lose
> some features. Also noticed video quality is not as good.
> Is there any other way I can retain spark VideoDisplay?
