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. + a -- do it yourself http://antoine.villeret.free.fr 2013/9/27 Benjamin ~ 01xy <[email protected]> > 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 > > ++ > Benjamin > > Le 27/09/2013 09:21, Etienne Landon a écrit : > > 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.
