We are currently working on a Flex application for consuming
all types of media – a next-generation media consumption
platform. We launch in January and urgently require a fix. The
issue we are experiencing is as follows: We need iFrame components
for 1.) playing YouTube videos, 2.) displaying some html text and
3.) integrating Google AdSense. In order to display iFrame in front
of application, we need to set up "wmode" parameter, "opaque" as
value in html source code, but we get a long list of troubles when
we set "wmode" parameter for our application.
1. Transition performance issues: the Transitions become
very slow, and not very smooth
2. Mouse scrolling function is frozen on Firefox: Using the
middle wheel on a mouse is disabled…the page doesn't move up
or down. When we do scroll by dragging the scroll bar, video does
not scroll smoothly with application and sometimes stops in wrong
3. When flex popup window is displayed (video, html text)
the iFrame is still displayed in front of the flex popup. This
means that some action buttons on the flex popups cannot be
4. When we play YouTube video in iFrame, the cursor
can’t focus on any input boxes (i.e. search box). We need to
click on url box to reset focus and then we can type in input
box…a Firefox issue.
All of these problems are coming from the "wmode" we set up
in html source code.
If anyone can please provide some assistance or suggestions,
it would be greatly appreciated. We would even consider financial
reward for a solution to these issues.
