<div>Hello,<br>
<br>
We are using a blackmagick decklink quad on linux<br>
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
<a href="http://wiki.labomedia.org/index.php/AstroFluxTechnique#bmdcapture_.7C_ffmpeg" target="_blank">http://wiki.labomedia.org/index.php/AstroFluxTechnique#bmdcapture_.7C_ffmpeg</a>)<br>
<br>
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<br>

</div>
<div>Regarding Blackmagic on linux you have to use gstreamer
through pdgst.</div>
<div>There are two plugins "decklinsrc" and "decklinksink", this
is working great !</div>
<div><br>
</div>
<div>I think they are in the "bad" plugin set</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>And I confirm, never change settings while using it,
unplugging the blackmagic input whit gem on freezes my
computer</div>
