Error: unable to init FlowLib [code 0x3FFFB] in Windows 8 Pro x64 (Page 1 of 2)

berryracer
Thank you for bug report.

This error [0x3FFFB] was on SVP with NVIDIA cards in early versions. It was fixed.
Error tells about video memory leaks.

1. Can you compare used video memory values via GPU-Z on both last SVP versions: 3.1.3 and 3.1.4?
2. What NVIDIA drivers do you use?
3. SVPmark works fine or with errors too?

Alright thanks man. I will let you know if it happens again

All i can say now - rollback to the last working nv driver version

berryracer
Probably NVIDIA changed something in drivers 314.* and NVIDIA drivers became incompatible to SVP commands.
You can check it. It is simple. Just install older driver with advanced option and clean install option enabled.

If older driver will work fine then return to newest one. Check again. Else go back to more older driver. What driver version works fine at your system?

Error not in ffdShow. Error occurs in SVP library. It can not init OpenCL hardware acceleration.

Now you only one with error 0x3FFFB.
It give me think something wrong with your system, with your OpenCL-driver or with your video driver. NOT with SVP.

I went back to GeForce Driver 310.90 (x64) but same error
Go down to next WHQL-driver: 310.70, 306.97, 306.23.
Or you don't want to fix the error?

please help
Can you attach here your CLInfo output?
Start menu - Programs - SVP - Utilities - CLInfo

berryracer
How do I attach the CLInfo you're talking about?

copy text from appeared notepad and paste it here in the post

UAC is disabled always and I am the admin

ffdshow video settings open just fine

Randomly means 90% of the time, 10% of the time it works...

when I go home, I will try enabling pagefile to a 1 GB min / max as I currently have Pagefile disabled...just to see if it makes any difference...

Also, I was reading on another forum about people having trouble installing codecs on Windows 8 as in they are not working...could that be a reason you think there should be some kind of trick to get codecs working?

Read this if u have time: http://forums.mydigitallife.info/thread … ptop/page2

I am thinking, even though I disabled UAC, Windows still asks me twice before copying, deleting, etc. a file to C:

I read online that there is a registry tweak that totally disables UAC I will also try that when I get home:

As soon as the video starts, you know how there is usually a 2 second delay until SVP displays the message on the screen that it is playing the video @ 60 FPS? Well with me, the movie starts fine for 1 second then by the time SVP is preparing for smooth playback it gives me the error with that ffdshow cannot access bla bla bla message

do you want to logon to my computer within 2 hours on TeamViewer
Yeah! It will be great but I don't know how to find the problem. I'm not master of OpenCL
Chainik can do more than I can. He has another time zone. He will contact you.
