I see a change between s4 and s3 in the CompositionPlayer sample in that MediaPlayer in s4 is now being accessed via MediaPlayerWrapper.as (vs in s3 via FlexMediaPlayer.as).
Thanks again to all of the team for your great work.
Nice catch. MediaPlayerWrapper is not permanent, it's just an example of a Flex wrapper for MediaPlayer. (It seemed better factored than the previous FlexMediaPlayer, so I opted to integrate that and retire FlexMediaPlayer.) That being said, we probably do need an official MediaPlayerWrapper (or to be more consistent with OSMF terminology, a "MediaPlayerUIComponent"). There's some debate amongst the team about whether the framework should contain such a class, or whether developers who want a Flex wrapper should use the Flex Component Kit for Flash to convert the MediaPlayerSprite to a Flex component. It's a tradeoff between ease of use and keeping the framework lean.
Any preferences from the community?
+1 "ease of use"
-1 dependency on "developers who want a Flex wrapper should use the Flex Component Kit for Flash to convert the MediaPlayerSprite to a Flex component"
my 2 cents.
