Query live preview mode

[fla]

I want to write a plugin that will remind the user with an OSD overlay when in live preview mode and there has been no channel change for more than a specified time. To do this I need to query:

1) Are we in live preview mode
2) When was this channel selected (how long on current channel)

What API calls can I make to get this information?

I dont think it would be possible for you to do this.

Hi,

I think this is possible (at least part 2 is). You need to use the IEventNotification (?) interface. This notifies you on various events. You will need to monitor the channel name/number change.

On a channel name/number notification, you will need to:
1. Check if this is a new channel or not by comparing to the variable that keeps track of the current channel; (If this is first channel, go to 2)
- If the same channel, do nothing.
- If a new channel, then:
2. Set the variable that keeps track of the current channel to the new channel. If needed, set a variable to the time we switched to this channel.
3. Set a timer event/reset the timer so that you can be notified to display the OSD if necessary.

4. On a videostopping event, clean-up (ie stop the timer, etc).

The above steps are what basically needs to be done for keeping track of when the channel was last selected.

I am not too sure about how to check if in live preview mode. I am guessing it may be possible to ask GB-PVR (or maybe even be notified) the name of the file it is currently writing to (if in timeshift mode). Thus we are in live preview mode if no file is being written to.

Thanks for the tips. I'll give this a try.
