Curious about what (stream.sys driver-based applications) is .

[jonnyhillow]

The update today (kb3054476) says it's for when you use (stream.sys driver-based applications) , what exactly is that?

Looked on "google" but not much help , i have Win 7 64 bit SP1 .

Thank you

Could be for Windows Media based Application, webcams (not entirely sure) ect...Got it too today's evening.

I will be waiting for a couple of days before installing this, just in case.

Yeah , i read all that before i decided to post here , Microsoft really doesn't explain what that is exactly .


They need to explain what (stream.sys driver-based applications) are .

Hello,

You can obtain informations via the MSDN site under the URL: https://msdn.microsoft.com/en-us/library/windows/hardware/ff568275(v=vs.85).aspx

Bonne journée.

Thanks for the link.

From my understand the driver specifies the interface class GUID to register adapters in the PIO Mode or DMA Mode and put them in their proper group/range of peripherals, performs routine stream request block.
Looks stream.sys belongs to DVD decoder and USB Camera group and has something to do with Microsoft Direct Show.

I found a few place yet nothing informative - then I found a place that explains the application where you use the test for W.E.I. Windows Experience Index that would benefit from this update.

Welcome to Sevenforums,

It would be kind if you have that link, so we can read about too.

Edit: Ohhh...that was here that place , sorry....

Microsoft releases 13 optional Windows patches | InfoWorld

Therefore explains:
KB 3054476 -- According to Microsoft, this update for stream.sys driver-based applications in Windows 7 or Windows Server 2008 R2 "helps Microsoft improve the experiences when users run stream.sys driver-based applications in Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1, such as the performance and the quality improvements." This is a new patch.

After reading that I remembered that the cache file for W.E.!. is in C:/Windows/performance/WinSat/
That W.E.I. does not complete the task - keeps running yet finished. I assume its the problem solver.
I installed this update to see if it solves that problem. Its too much work to dump the cache file.

 

[NoN]

Ah, ok..you're running W.E.I right now?

I had no probs with WEI lately, but might run it too. Keep us in touch.

"helps Microsoft improve the experiences when users run stream.sys driver-based applications in Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1, such as the performance and the quality improvements."

Might be also for improvements of the streaming quality of the adapters plugged...

Was you referring to the part of the log in Run Assessment mediaex input dshow, you're troubleshooting?

Might the update have restored something in registry keys for you. From what i read most of WEI troubleshooting is about power plan registry settings not set properly.

My log shows error at start because i've forced the High power plan to be the default setting.

 

[jonnyhillow]

From what i gather this update sounds like it's probably worth installing.

 

[NoN]

From what i gather this update sounds like it's probably worth installing.

Yeah, its definitely not a harmful update, and might help the Microsoft API Direct Show performances.

 

[jonnyhillow]

Thanks for your help NoN and Steve .

 

[Steven284]

Was you referring to the part of the log in Run Assessment mediaex input dshow, you're troubleshooting?

Thanks - that is possible - if I could find the error in log.

I am thinking of the popup Video Display - explains task - then that it completed - yet popup does not exit.

In Windows - this is where Stream.sys is :

 

[NoN]

edit/open the C:/Windows/performance/WinSat/winsat.log and browse by last run, you should be able to trace the error inside the log.

Check again your Power Plan settings and have a look at that thread for infos:

Windows Experience Index not working

Look just in case at your registry if those key are well set in User "Default -PowerSchemes" & "PowerSchemes"

Hit Start=>Run=>type regedit, at prompt run as administrator and browse to those keys: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\User\PowerSchemes

If WEI run, then you do not have to worry.

 

[carwiz]

What does WEI have to do with streaming devices like cameras and projectors?

 

[NoN]

What does WEI have to do with streaming devices like cameras and projectors?

WEI is using the Microsoft Direct Show API when launching Index Score to evaluate the performances of encoding and decoding, that's why it was discussed here along stream.sys

 

[carwiz]

Yes, I'll give you that but I don't think the Stream.sys driver is used during WEI evaluation. I don't have a video capture card but I do have a TV card and WEI doesn't evaluate that. At least I've never seen it in the test log. Or perhaps I don't understand completely how/where the driver is implemented.

Tried to post image of Direct Draw components but the attachment link isn't working.

I'll report the attachment link issue to John, but for now if you click on the "Go Advanced" button, the attachment link will then work.

Thanks Shawn.

Added: I reported it from the error window but forgot to include the link then followed with another reply with link. Seems we are crisscrossing email now.


Test. Advanced works.
