OnMessage intercepting hibernation trouble

Recommended Posts

majstang

Since there is no userinteraction allowed with scripts runned from within Recording Service i made this Autohotkey script in order to intercept the hibernation call (coming from the After recording task im having with an OnMessage command)) and quickly close this function down. In this way taking control of the hibernation process and it gives me the opportunity to have some userinteraction using a script runned outside of RecService.

A messagebox pops up when hibernation is intercepted and gives you the following options:

Press "Yes" button and Hibernation initiates

Press "No" button script breaks and does nothing

If no presses are registred hibernation will initiate after 20 seconds

 

However i did come across a really annoying quirk:

 

If watching TV (DVBViewer is the activated window) when the hibernating call comes...this brings down the graph (DVBViewer goes black).

 

It seems DVBViewer is very sensitive and goes to far. Why does DVBV close the graph when it should not? TSPlayer and MPC-HC does not when the hibernation call is intercepted. Is there a way to make DVBV not behave like this?

 

Please le me know if something is unclear and i will try to explain better...im REALLY keen on getting this to work and would appreciate any thoughts anyone have on the matter. Im using the DVBV 4.2.1. and DVBV beta 160...both does the same.

InterceptPBMSG:

This will NOT work under Vista/Win7. PBT_APMQUERYSTANDBY and PBT_APMQUERYSUSPEND do not work there anymore. And it might interfere with the task scheduler.

 

What does the debug.log say, if you start the viewer in debug mode?

Yes, I know Im using XP, but if someone wants this script to be adapted to Vista/Win7 there is a way.

 

And it might interfere with the task scheduler.

In what way do you reckon?

Here is the debug.log and as you see sessions ends with:

Powermessage PBT_APMQUERYSTANDBY

 

Which im not using...should be PBT_APMQUERYSUSPEND if something at all.

 

Howcome DVBViewer closes graph when it really shouldnt, cuz function should be closed before even reaching DVBViewer? No other player i have tried acts this way. Only DVBV is affected.

 

Debug.log taken when the hibernation call is made and my script intercepts the hibernation and DVBV graph closes during the OnMessage part in my script:

Hi Lars!

 

Would like to hear your opinion about this. Is it a inconsistency of DVBViewer...maybe this topic belongs in Bug Reports/DVBV beta? And most intresting of all, at least for me, is it fixable? :)
