Resumed from hibernation - GBPVR hangs the system

[steyr]

Hi.

When the computer resumes after hibernation (e.g. for updating EPG). - Windows freezes completely.

Heres how I reproduce the problem.

1. GBPVR is running - from within the application I choose: Hibernate
1. The PC wakes up to update EPG
2. After downloading EPG - I right-click the icon in the systemtray -> Update EPG
3. To get an updated TV-guide I shutdown GBPVR
4. When I try to restart GBPVR - Windows freezes completely.

Hitting CTRL + ALT + DELETE doesn't do a thing - the only way to regain control is to hard reset the computer.

The problem seems to be related to using the TV-out.

If I disable hardware encoding - the problem seems to disappear.

As I really would like to take advantage of my TV-out on the Hauppauge card - it would be nice if theres something I could do to make it work.

Any suggestions anyone?

When I look in the gbpvr.exe-native-1.log - I see the following error.

12:59:02.296 ERROR SetGlobalAlpha - IKsPropertySet->Set IVAC_OSD_GLOBAL_ALPHA failed
12:59:02.343 VERBOSE DirectShowHelperPVR350::ShowImageUsingPVR350()

12:59:02.343 ERROR SetOSDState - IKsPropertySet->Set IVAC_OSD_STATE failed

(see attachment).

If you search the forum for keywords such as "350","hang", "hibernate", you will find that you are one of many people who has had this problem.

>If I disable hardware encoding - the problem seems to disappear.

that's what most people do (inc. myself) to resolve this.It appears to be a 350 driver bug that never got fixed by the manufacturer.

shame but there you go.

Hi gEd

I've done tons of investigation on this topic - and tried quite a few things - so far - no luck

I stumbled across this thread by Mabo:

I am using the latest drivers but don't seem to be as lucky as him.

Mabo -> Your thread was posted in 2004 - and I suppose that the drivers available at hauppauge.com are newer than the ones you refer to....
If you read this thread - please respond

More info:

Tried downloading a trial version of SageTV 4.0 to see if the same problem would occur when resuming from hibernation...

It didn't - so I don't think its a (hauppauge) driver problem?

Also I found this in the documentation for SageTV:

If Windows is configured to go into standby mode after a period of inactivity, SageTV will set a timer for the system to resume operations in time to record a Favorite or Manual Recording. If needed, all capture devices and video hardware will be reinitialized so that SageTV will continue to be able to use them

Apparently this is taken care of by a program/service called SageTVService.exe

Something similiar would be possible with GBPVR?

I know I could just switch to SageTV to have my problem solved - but having tried GBPVR for a while - I would prefer that anytime over SageTV...

see here for what you're looking for.

It might sort things - might not. Many people have given up with the 350s TV out. if you can get it working its very nice though...

EDIT: i just followed your link and you linked to the same thread as the one i did. If youve followed the wake.cmd/devcon route and it didnt work then im not sure what else to try. you may have to settle on software decding instead.

Hey ricklous..

Just out of curiosity...

I can see that you live in the UK..

Do you have a hauppauge card - and if - do you use the tv-out?

For now I'm not keen on giving up on the tv-out - it must be possible to get it working - at least some people seem to be successful with that...

If you happen to stumble over any (new) solutions - please let me know

[ricklous]

Yeah I have used the 350s TV out.

It gives an excellent picture. It was a long time ago (at least thats how it feels!) since i tried it, but i think the only problem i had was a system lockup if i tried to ff. But to be honest, before i could find any other bugs i switched back to software decoding when i realised the limitations of the card. You cant play DVDs/AVIs etc without some form of transcoding on the fly, you need to reroute the sound back into the system if you want to hear anything else other than the 350s sound and the new features like video in a window wont work on it either.

The general belief is that the problems are hardware related - which is why they are so hard to solve. Ive also read that it seems to be that people on certain chipsets have more problems than others - but it was never pinned down exactly and even if you say 'this chipset will crash your 350', you'll probably find someone out there whos not had that problem.

Its annoying because of the great picture. If you *just* want to watch TV and thats all, then it might be worth doing more hunting for a solution, and your best bet is probably the hauppauge forums, but there may come a point where you have to just give up and use software decoding, for your own sanity if nothing else

Hi Guys,
Well the hauppauge pvr 350 hibernation problem has again turned up, apparantly. To answer the question by steyr: I'm still using the drivers that I reported as working with hibernation. As my system has been running very well on these drivers, I didn't take courage to change it (if it ain't broke, don't fix it).

However, the gbpvrwake and wake.cmd route should still be working for ssetups where hibernation does cause problems. You have to be sure that the card is not in use by any process whatsoever (IR.exe, teletext, recording etc) before you can restart the card with devcon without a reboot. The wake.cmd I posted takes care of most of these processes.

I'll keep watching this thread...

Greetz,
MaBo

Hi ricklous!

First of all - thank you for taking time to respond to my thread - even though you don't solve my problem - you keep up my spirit :-)

It gives an excellent picture. It was a long time ago (at least thats how it feels!) since i tried it, but i think the only problem i had was a system lockup if i tried to ff. But to be honest, before i could find any other bugs i switched back to software decoding when i realised the limitations of the card. You cant play DVDs/AVIs etc without some form of transcoding on the fly, you need to reroute the sound back into the system if you want to hear anything else other than the 350s sound and the new features like video in a window wont work on it either.

The main purpose for my machine is to record and playback TV.
However I agree with your comments regarding the limitations with AVI/DVD and the lack of better sound than what hauppauge is capable of delivering...
When I first discovered this - I was quite disappointed, since I had bought a decent sound card for my HTPC... then thought, what the heck - the main purpose is to record/playback TV, so I'll live...

...if just I could save my system from completely hanging upon resuming from hibernation...

The general belief is that the problems are hardware related - which is why they are so hard to solve. Ive also read that it seems to be that people on certain chipsets have more problems than others - but it was never pinned down exactly and even if you say 'this chipset will crash your 350', you'll probably find someone out there whos not had that problem.

You're probably right about this - but I will submit some details about my HTPC - just in case it could give a hint in some direction.
Here goes:

- Mobo: Abit IS7
- Intel Celeron 2.93 GHz
- #1 HDD: 80 GB Seagate (Win XP OS)
- #2 HDD: 160 GB Maxtor (For recordings)
- 512 MB RAM (Kingston - If I remember correctly)
- Hauppauge PV350 PCI with EURO-SCART connector (latest drivers installed)
- LiteOn DVD RW Drive
- Matrox G400 32 MB RAM**

** Just noticed that the Matrox card doesn't seem to support hibernation all that good - sometimes it leaves the screen all scrambled when resuming from hibernation... I will try to replace this with a newer card - just to see if it makes a difference...

Could it possibly explain this error in my log:

12:59:02.343 ERROR SetOSDDisplayBuffer - IKsPropertySet->Set IVAC_OSD_DISPLAY_BUFFER failed

(Sub - could you elaborate on this?)

One final question ricklous.

What graphic card do you use for TV-out (If I have to surrender to software decoding)..
Have tried a couple of cards - but I'm not satisfied with the quality (S-VHS connection)..

[steyr]

Hi Mabo!

Thank you for replying to this thread :-)

Just to make sure I got it right.

- You are using the same drivers - you referred to in your "old" thread?
- You do NOT need to have GBPVRwake.exe and wake.cmd running to restart you Hauppauge card - to avoid the "colour-bars-screen-on-tv-out-after-hibernation"?

Do you know where I can find these exact drivers?
If it is not too much of a hassle - maybe I could download them from your web-site (if you have one) or you could send them to me (I have a gmail account..)

You have to be sure that the card is not in use by any process whatsoever (IR.exe, teletext, recording etc) before you can restart the card with devcon without a reboot. The wake.cmd I posted takes care of most of these processes.

Meanwhile I'll have a second look at wake.cmd and any services accessing the card to make sure that everything is covered...
