Hello
the only problem with the Linux drivers for the Blackmagic cards is,
as far as i discovered,
that they are not initialising the cards video-device in /dev/video*
this unfortunately makes it impossible to "just open" the cards input
with pix_video :(
or did they change that in the meantime?
cheers, peter

hello
i have a bm intensity pro here on win 7
it can work , but switching source sometimes crashes pd .
i send message
[driver 1(
to pix-video prior to open gemwin
its think it tells pd to use wdm wich is an older video driver
then select input .
it's not perfectly stable sometimes ..
tell me if you find a way of getting good results

Hello
i recently ran into a somehow similar problem.
until now i haven´t found the time to pu my finger on it, but
i thought, that i my case, it was somehow related to the high
framerate/resolution (1080p/60), which of course should not be an issue
could you just try with 720p/30? changing the colorspace?
cheers, peter

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.
