UiStatic vs UiElement?

[imilne]

Can anyone explain what the difference is between them and when I should be favouring one other the other?

UiElement is much lower level. It's probably best to avoid using this directly if you can.

That's all I needed to hear

As a (kind of) follow up to this question, the reason I was asking is because I'm building an IScreenPlugin that needs to display information over playing video (including Live TV). I'm activating it in response to a keypress with:

Code:

PluginHelperFactory.GetPluginHelper().ActivateScreen(...)

This works, but only after the initial MetaData overlay (the Alt+B one) has disappeared. No amount of keypressing activates it before that (in fact I think it only keeps the MetaData on screen even longer). Once there are no overlays, then mine will respond and appear. If the MetaData one is brought back, mine can override it straight away if desired.

I was just wondering if there was a reason for this behaviour - and if so, that's fine - or if I'm perhaps doing something wrong?

Oh, and as a follow up to the follow up, if I activate my plugin while the Now/Next details screen is visible, then NPVR throws a NotImplementedException when it tries to deactivate it.

Code:

System.NotImplementedException: The method or operation is not implemented.

Ok, I've fixed this for the next release.

The built in metadata overlay does work differently to other OSD overlays, so it might not be possible to override it. It wasn't intentional, but not something I've tested.

[imilne]

Thanks sub.

I'll set OSDTimeoutInfo in config.xml to a really low value while testing it, as it's amazing how long 4 seconds is when you're waiting to test something (over and over and over...)

Sub, I see that the API has IPluginHelper.SetPlayerMetaData(Hashtable) - would it be possible to add a GetPlayerMetaData so that any active details can be read back by another plugin?

I'd like to be able to get the title, poster, channel logo, etc of whatever is playing.

Edit: actually, on second thought the poster might not be possible because it's often a reference to an image callback isn't it?

Thanks
