Recording from standby

[robmh]

Hi

Before I start, thanks for a great piece of software. (Donation imminent.)

I have GBPVR installed and working fine apart from one issue which I suspect is down to shortcomings in my capture card/drivers.

I tried setting my system up so that it would go into standby (S3) and come out of standby to make recordings. According to the logs, recording starts but the files are always zero length (0KB).

I even tried rebooting in wake.cmd but this doesn't apear to fix the problem!

Setup:
- Intel mobo with dual-core CPU.
- Hauppauge WinTV Nova-T PCI tuner card.
- HD 3450 graphics card. (Using ATI Decoder and MUX)
- GBPVR 1.2.9.
- MCE Standby tool.

I also tried hibernating but the recording service wouldn't wake up the PC reliably.

Does http://www.hauppauge.com/html/sysreq.htm mean that WinTV PCI cards don't support standby?

As I'm using the ATI Decoder and MUX, could the problem be due to the GFX card and not the tuner card or are these only used during playback?

Any other suggestions?

BTW, do I need to run gbpvrwake.exe at startup or will GBPVR call wake.cmd anyway?

Thanks in advance for any help.

I think gbpvrwake has to run from startup for wake.cmd to be started up.

Try playing with the "power management" option your tuner in device manager (if that tab is available).

GFX card not involved in recording.

My wake.cmd contents:- (pings are to get my network up to speed)

@echo off
set logfile="E:\Program Files\devnz\gbpvr\logs\wake.txt"
echo ===================================== >> %logfile%
echo Wake from standby on %date% at %time%>> %logfile%
"E:\Program Files\devnz\gbpvr\FullResume.exe"
net stop "GB-PVR Recording Service"
net start "GB-PVR Recording Service"
ping 192.168.1.254 -n 5 -w 1000 >> %logfile%
ping http://www.ja.net -n 5 -w 1000 >> %logfile%

There have been addition to wake.cmd by others to use 'devcon' to stop and restart pci devices.

I'd post the full logs as well, in the hope that sub can spot something out of the ordinary.

Thanks for the feedback. I'll try your suggestions.

The reason I thought gbpvrwake gbpvrwake might not need to be called is that wake.cmd is listed in the "GB-PVR Calls These Batch Files" section of
http://gbpvr.com/pmwiki/pmwiki.php/Manual/BatchFiles .

BTW, I've tried restarting the tuner card with devcon but a reboot is needed to complete the action so I thought I might as well reboot.

I'm going on the gbpvrwake.exe from some of subs posts :-

I saw that message too but I thought things might have changed since 2006.

Returning to your original suggestions, why do you think FullResume.exe might help? Doesn't it just activate the display?

BTW, whenever this problem happens, if I interract with the PC while a recording is "in progress" (even though the file is zero-length), recording then starts i.e. it's as if the timed wake-up only partially restarts the system and it is only fully restarted when someone uses the PC.

I've been 'alerted' to the discrepancy on the wiki.


I'll change the entery, but I am confused. I never used it myself. It was just that I took it upon myself to work on the wiki a while ago...

Is someone saying that gbpvrwake.exe is a requirement? and that it should be running from the startup folder, for the wake from standby feature to work?

[gEd]

for wake.cmd to be run yes, gbpvrwake.exe needs to be running all the time (from startup folder)

Hi, I have a Nova-T waking from standby and recording with no probs. Make sure the wake.cmd file is killing and restarting pvrx2.exe rather than gbpvr.exe though

Sorry, it just happened to be in there to solve a problem of mine.

Most odd in your case that user action can start it off, I can't think what could still be asleep that windows would startup.

[robmh]

Yes, I agree, very odd.

This is why I thought that the ATI MUX might be involved as I ASSUMED that it used the the HD 3450 hardware which might not have (fully) woken up.

If this is a possibility then I suppose I could try another MUX but I'm really clutching at straws here. (Originally, I used the MS MUX but this failed when recording a black screen on C4 - a known issue apparently.)

Note that I've only just added a Nova-T Stick to my system but I haven't yet tried it in standby. (All my comments so far refer to the Nova-T PCI card.)

I guess that I need to do some more rigorous testing to get a better handle on the problem but this is somewhat time consuming due to its nature.

Anyway, thanks for the comments so far.
