Unfortunately when adding cuePoint event listener to mx:VideoDisplay component in Adobe Flex 3 you only receive name, time and type of the Cue Point. Here is a dirty workaround to access the parameters from the metadata. <?xml version="1.0" encoding="utf-8"?> <s:Application minHeight="600" minWidth="955" xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx"> <fx:Script> <![CDATA[ import mx.core.mx_internal; import mx.events.MetadataEvent; import mx.utils.ObjectUtil; protected [...]

Unfortunately the standard way (‘\n’) of inserting new lines in Flex Text Controls (Label, Text etc) doesn’t work when the string comes from XML. The magical way to do it is by using ‘‘ so LoremIpsum becomes Lorem Ipsum

If you get this error on each frame then you have probably moved the camera to the same position as the object (camera.z = 0). Change it a bit and the error should be fixed.
