Hello Oriol, we have a couple of capture agents with Epiphan VGA2USB and also Blackmagic Intensity pro capture cards with ALMOST no problems running on Ubuntu 10.04 and 10.10. The problems we found were due to USB microphones and Pulse audio drivers, and try to record HD quality video. We get out of sync video&audio, but this is another problem. So I will send to your email a file with all the files of the 'gst-decklink' repository, so you can continue the installation steps for the Blackmagic card.
(If someone else is interested and/or there is no problem to attach it to this email, please tell me and I will do it) Best regards, Fernando Hernandez *Cloudpe Corp.* 2012/11/21 Oriol Pellicer i Sabrià <[email protected]> > Sorry: I meant in the second paragraph that I have a v4l device, not a > v4l2 one. > > > Greetings, > > Oriol. > > > > 2012/11/21 Oriol Pellicer i Sabrià <[email protected]> > >> 2012/11/20 McKenzie, Adam <[email protected]> >> >>> Hi Oriol,**** >>> >>> ** ** >>> >>> I noticed you had “location=/dev/vga2usb0” for your epiphan capture >>> device.
