Subject [jira] [Updated] (FLEX-34642) Playing recorded video from Wowza in a Spark VideoDisplay shows black screen but plays sound only
Date Fri, 21 Nov 2014 13:55:34 GMT

     [ https://issues.apache.org/jira/browse/FLEX-34642?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Erik de Bruin updated FLEX-34642:
---------------------------------
    Attachment: ApplicationStageVideoEnableSkin.mxml

I don't know about OSMF, but I think it's a wrapper for the Video and StageVideo objects,
correct? If so, I recognise the problem, and it's indeed related to using StageVideo. You
can solve it (at least when wrapping the above objects yourself) by adding the attached skin
(ApplicationStageVideoEnableSkin.mxml) to your Application, like so: 

var application:SkinnableComponent = SkinnableComponent(FlexGlobals.topLevelApplication);
application.setStyle("skinClass", ApplicationStageVideoEnableSkin);
