[PD] pix_video problem

[Pierre Desprats]

Hi,

I'm having trouble with pix_video.

I'm using a sony PWM200 in 720p/50p,
A BlackMagic Decklink Studio with HD-SDI input connected in PCIe.

I'm testing on a windows 7 with Pure data 0.43.4 and GEM 0.93.3

Drivers are correctly installed and when I send "enumerate" to 
pix_video, it shows me two devices :
Blackmagic WDM Capture Directshow
Decklink Video Capture Directshow

but when I choose one (it doesn't matter which one), i got the error : 
"could not start graph playback, hr 0x80070057"
Slightly after, pd crash.

I certainly miss clues to understand what's happening so I hope someone 
could light me up ?

Thx.

P.
