How to install two DV codecs?

[SerbianBoss]

I am interesting in how to install to DV codecs (panasonic and cedocida) in same time so that i can change codecs.

For example if i would like to capture in panasonic and other tape in cedocida.

thanks

Just install both of them. They shouldn't clash. But you can only use them to capture is you have an analogue capture card that can use vfw codecs through software like virtualdub.

If you source is mini-DV tape, or coming in through an analogue to DV converter then neither will be used because the hardware has already done the encoding and you are just transferring encoded data.

If you are looking to compare the two, any video on your HD will suitable. Just load it into virtualdub, resize to DV spec, and choose which one to save as.

It's true they won't clash but only the one that is installed last will be available to VfW applications (if the application relies on the OS to find the codec).

Both the Panasonic and Cedocida DV codecs are VfW codecs. The VfW architecture only permits one codec to be registered with a given FourCC at any given time.

To switch between the two, you either have to reinstall the one you want to use before using it OR make a fairly simple change to the registry at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32

DirectShow does not suffer from this problem and you can have as many variants of DV encoders and decoders as you like.

And what to do when i type:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32

How can i switch between two codecs in registry?

thanx

Find the Value Vidc.dvsd, and change the data to point to which ever codec you want to use. Simplest method - install the one of the codecs, find the key in the registry and export that value to a .reg file. Install the other codec, and repeat, creating a new .reg file. Whenever you want to alter codecs, just merge the correct .reg file.

This tool might help: VCSwap

Just to be sure:

I first install for example cedocida. Go to registry fing Vidc.dvsd and export for example to desktop(now i have cedocida.reg file).

Then i install Panasonic codec,go to registry, find vidc.dvsd and now export to desktop.

So i now have to registry. And if i want for example to work with Cedocida i just click on cedocida registry(witch i export to desktop). And if i want to work with panasonic i do the same. Is this ok?

I will try VCSwap to see how works?

[guns1inger]

I suspect that VCSwap does pretty much the same thing, but alters the registry directly, and covers a wider range of codecs.

[SerbianBoss]

So it is the same if i work with VCSwap or if i export cedocida and panasonic dv codec and than manually and to registry.

If you open the .inf file that comes with the codec (using Notepad), you can see exactly which registry keys are affected.

In addition to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32

there are also changes to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\MediaResources\icm\vidc.dvsd

[SerbianBoss]

When i open cedocida with notepad i have this:

[DVR.Add.Reg]
HKLM,SYSTEM\CurrentControlSet\Control\MediaResources\icm\vidc.dvsd,Description,,"Cedocida DV Codec"
HKLM,SYSTEM\CurrentControlSet\Control\MediaResources\icm\vidc.dvsd,Driver,,"cedocida.dll"
HKLM,SYSTEM\CurrentControlSet\Control\MediaResources\icm\vidc.dvsd,FriendlyName,,"Cedocida DV Codec"
HKLM,"Software\Microsoft\Windows NT\CurrentVersion\drivers.desc",cedocida.dll,,"Cedocida DV Codec"
HKLM,"Software\Microsoft\Windows NT\CurrentVersion\Drivers32",vidc.dvsd,,"cedocida.dll"

And in registry(when type KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control \MediaResources\icm\vidc.dvsd)i have this:



My question is:
What to do with this new registry(picture).Does i need also this(this four data) to export like i export Vidc.dvsd ? I mean can someone explain proper way of installing two dv codecs and how to change them.

[SerbianBoss]

To be precise:

When i install (for example cedocida dv codec first) what to do ? What to export from registry?

Because i want to have two dv codec on system cedocida nad panasonic.

So,what is proper way to do this.

thanks

Test VCSwap. If it works, use it. Both codecs can be installed on the system together, however only one can be associated with the correct fourCC at any given time. If VCSwap lets you switch between them, use it instead.

Just one more question. If i first install cedocida and than panasonic dv, and if disable panasonic(in vcswap) can i work with cedocida? I must test on another computer, so i am interested does you know does this work?
