HOW TO: Intervideo Decoder Registry Patch for GBPVR

[csy]

You may wish to start by stripping-out the registry patches. Launch Regedit and navigate the tree structure to the 'GBPVR' sub-key within the specific decoder key. Right-click the 'GBPVR' sub-key and select delete. This will take you back to where you were prior to applying the patch.

Alternatively you can play with the settings in the 'GBPVR' sub-key of the decoder.
The Intervideo Registry patch did 5 things:
1. Enabled DXVA
2. Enhanced DXVA to include HWCOLOR and HWMC acceleration (specific to Intervideo)
3. Enabled VMR7/9 capability (but application chooses which renderer is actually used)
4. Ensured 'auto' de-interlacing (default anyway)
5. Enabled DD/DTS 5.1 audio decoding.

The two key parameters are DXVA and VMR

csy,

I just had a thought (yes it hurts), based on some of your notes:

This is a universal Nvidia Purevideo decoder registry patch which Purevideo decoder will use on all applications.

This registry patch can be adapted to work with other Directshow applications be replacing the ‘GBPVR’ tail-end of the key with the valid registry name of the alternative application.

As GBPVR is on the tail end of two of these patches, would it be fair (correct) to say that the Intervideo and Cyberlink registry settings are only activated in GBPVR itself, hence I need look no further than the PureVideo registry patch for changes?

With respect to your Mplayer Classic issue, you are probably correct, although WRT to Intervideo /Cyberlink check to see if MPlayer Classic has automatically added its own sub-keys with the decoder tree.

A recent discussion resulted in the conclusion that if you wrap code (# button in forum) around these listings, you won't get those (unwanted) added spaces.

I tried # and that didn't work.
I also tried [#] and that didn't work either

eek...sorry. I looked at this thread.

Let me test it ..

Code:

REGEDIT4

[HKEY_CURRENT_USER\Software\InterVideo\Common\VIDEODEC\GBPVR]
"BOBWEAVE"=dword:00000000
"DXVA"=dword:00000001
"HWMC"=dword:00000001
"NVMCP"=dword:00000001
"VMR"=dword:00000002
"HwColor"=dword:00000001

[HKEY_CURRENT_USER\Software\InterVideo\Common\AUDIODEC\GBPVR]
"AUDIO"=dword:00000005
"AUDIOCHAN"=dword:00000004

Hmm... CODE ... /CODE (in square brackets, i.e. the # BUTTON (not the # symbol itself, in the forum menu - sorry I wasn't clear on that) appears to work for me. Perhaps you just forgot to remove the original spaces when you tested it :-) ?

Got it - thanks.

How do I know if I need these reg patches? As far as I can tell GBPVR works just fine - does this mean I don't need the patch, or that it would work 'better' with them applied?

[csy]

The patches principally do 3 things:

1. Enable MPEG2 hardware acceleration to reduce CPU load
2. Enable hardware de-interlacing which provides a sharper picture on LiveTV and TV recordings than default software de-interlacing
3. Enables DD/DTS 5.1 decoding (default is stereo)

If you are satisfied with the default picture quality and sound, then there is no need to install these patches.

After installing this patch my recordings play in fast forward. Anyone have any ideas how to fix this? Is there a value I can change in the patch to prevent this problem? I think via my codec pack hardware acceleration is enabled, can I just enable hardware deinterlacing somehow?

I have not come across this problem before.

You can remove the patch by removing the registry subkey, as per the last note in post 1 of this thread.

Hardware de-interlacing is implicitly enabled via using DXVA+VMR.
