WinXP : VFW to WDM wrapper

[CocoPops]

Can you use a VFW to WDM wrapper under WinXP ?
(to make VirtualDUB work)

[PatMar]

that depends if there is an WDM driver available for the capture card that you are using.

in the next 2 weeks there will be an WDM beta driver available for the Studio DC10+ cards that can be used with a lot of video editing programs

For ATI Radeon you don't need any wrappers.

[stanwebber]

the wrapper is for the benefit of software that communicates with hardware thru the vfw architecture. if you want to use virtualdub, avi_io etc... with the ati radeon you need the wrapper

[CocoPops]

Just installed a clean version of WinXP and the new XP display driver from ATI homepage and their MMC7.2 software, and to my surprise I could capture in Vdub at 704x576 without installing anything else....

So it seems that FilComArt was right

BTW I have a ATI AIW RADEON

Anyway, the drivers to the RADEON is of the WDM type, so how come Vdub work?

[sommersby]

Yup, I had to install the wrapper on windows ME when I first installed my AIW radeon with the newest drivers and mmc 7.2. When I did a fresh install of Windows xp, using the drivers and mmc 7.2 for xp, I did not have to reinstall the wrapper and I can capture at any res I want to in vdub.

SHS, i don't suppose there's any chance of getting your forum put in the links here is there, I keep trying to send people to it but I can never remember the address

the microsoft wdmvfw mapper is installed by default in winxp. it's also installed by default in directx8.1 & the video capture update for directx8.0(a) if prior wdm drivers exist on your system. at this time virtualdub can only communicate to hardware thru vfw period(god i hate repeating myself)

Question...
what is a wrapper?

[Shabubu]

It makes the program think it's talking to VFW, when it's actually talking to WDM

[mtremel]

Im using Virtualdub, but dont think i am using that.
would that be why i can not capture above 352x240?
(It looks like its a microsoft driver it is capturing from)

[mtremel]

Think im getting in the right direction...
Thanks guys...
