Hi,
sorry, I'm answering really slowly but I couldn't have a SDI camera
since I posted my question.
Today I made some new tests, and guess what; it's working.
The only thing I changed is that I have 2 new devices : usb camera and
an Osprey card for SD camera.
The blackmagic driver works only if the usb camera is connected. When I
disconnect, I loose the signal and PD crash.
When the usb camera is plugged, everything is stable and works fine.
Mystery.
Thanks for your help, I'm sure thoses informations will be usefull
really soon.

hello,
to reduce CPU eating, did you try to put each [pix_video] in a
separate pd~ and then send the image to a main patch with [pix_share_*] ?
this could help
I never worked with blackmagic card but it could be possible to add a
new backend to [pix_video] to support those cards "natevely" in pd.

Hello,
We are using a blackmagick decklink quad on linux
to get the signal threw pix_video, we use the bmdcapture command
line tool combined with ffmpeg so as to write on a virtual video
device created by v4l2loopback (cf
http://wiki.labomedia.org/index.php/AstroFluxTechnique#bmdcapture_.7C_ffmpeg)
it works fine and it is stable even if we plug/unplug the video
sources, it allows us to capture 1080i video or PAL video
encapsulated in the SDI signal, but if we try to capture 4x1080i
signals, the framerate is less than 25fps as Pd is > 100% CPU

Hello list, my first message ! youpi
Regarding Blackmagic on linux you have to use gstreamer through
pdgst.
There are two plugins "decklinsrc" and "decklinksink", this is
working great !
I think they are in the "bad" plugin set
If this works the same in windows, perhaps you have to fisrt set
the mode of the blackmagic before turning gem on. By setting up I
mean selecting the appropriate input and video resolution.
And I confirm, never change settings while using it, unplugging
the blackmagic input whit gem on freezes my computer
