Vista - Media Seeking Issue

In the current release (June CTP) of WinFX/.NET 3.0, there is a problem
with seeking through video while it is paused. This problem has been
around for some time. I saw a previous post mentioning the bug, and a
reply was given that Microsoft is "investigating implementing this for
future builds." To me, this seems like a pretty important feature, and
it still has not been implemented. Without it, things like going frame
by frame through a video are impossible, not to mention the inability
to even have such an extremely simple setup of a MediaElement, and a
slider and play/pause button to control it. Are there any updates on
this?

If you are referring to seeking in paused state not working at all, you need
to set the ScrubbingEnabled flag to true in order to get this feature.
There is a _slight_ perf cost of having this functionality, so it is not
enabled by default.

If you are referring to a different bug, could you provide more details?

Thanks,

ScrubbingEnabled is a property of the MediaPlayer class, which was
decoupled from the MediaElement class. So, I cannot simply set this
property. Is the MediaPlayer class no longer used at all? How am I
supposed to enable this property for a MediaElement?

This property is also on MediaElement.

So it is. And it works wonderfully! However, it appears to be
undocumented (or at least I was unable to find anything). It doesn't
even appear in the Visual Studio auto-complete list for some reason,
which is why I thought it didn't exist.

Thanks a lot for the feedback! My guess is that had an older version of the
WPF Extensions to Visual Studio (this is a relatively new property). In any
case, we will make sure the extensions and our docs are updated.

Thanks again,
Ed
