point 2 is workaround to make it sure it display everytimes, but it
disables the performance gains from stageVideo.
I finally got everything clear now i think:
as it is said in the link, justin provided, the stageVideo is displaid
under the Display list, so everything that is drawn above can obscure or
hide the video in this mode.
in flex, by default stageVideo is not used for video not in fullscreen
state (because it assumes that theres too much risks to get something
above it)
and by default in fullscreen it will activate the stageVideo, because it
assumes that everything else is hidden.
in flex app, by default backgroundAlpha being not null, it will obscure
the video when it uses stageVideo, so it hides the video in fullscreen
even if we use directly OSMF components. That is the bug i had in 4.11
if you add wmode="direct" in app html wrapper, it will force videos to
use stageVideo everytime, that means also in non fullscreen mode.
thats why if you set this mode in 4.11, it hides the video everytime!
So without VideoPlayer component:
we just need to set backgroundAlpha="0" and it will fix fullscreen, and
non fullscreen with wmode=true.
But for the VideoPlayer SDK's component, it is not enough!
We still have 4.11 bug with: no video displaid at fullscreen + no video
even in non fullscreen with wmode="true"
That is because of the videoPlayer's skin which contains a black
background Rect under VideoDisplay, which will be displaid above video
in stageVideo mode.
Trying to have stageVideo usage as default behavior would require
changes that would be issue for backward compatibility of visual
designs. (like backgroundAlpha to 0 as default)
So the safest solution is to set OSMFSettings.enableStageVideo = false;
in SDK and tell that Flex SDK don't use stageVideo by default (like it
was the case with previous versions).
but if someone wants to use stageVideo, he must:
1- call OSMFSettings.enableStageVideo = true; at App creationComple for
example (depends where you put the false set in SDK)
2- add backgroundAlpha="0" to App
3- use a custom skin for VideoPlayer component, in which he deletes the
black background Rect
4- add wmode="true" to get stageVideo in non fullscreen state also
in any cases, we can't let 4.11 default behavior with this bug.

Hi,
Looks like this[1] explains the issue and conains workarounds.
1. Add backgroundAlpha="0" to the Application container
2. OSMFSettings.enableStageVideo = false;
We could do the second in the SDK but no idea if that is a good idea or not.
Thanks,
Justin
