It can be installed from a deb file in the same way. There is also a GUI program in the DesktopVideo package called MediaExpress. You'll need to select the option that includes HDMI input. This utility is mostly used to activate particular hardware inputs and outputs, since not all can be active at the same time. See the readme in the archive for more details on installation.īefore doing anything with the card, you'll need to run the configuration program BlackmagicControlPanel. This will install the kernel module, the shared libraries, a configuration app, and a firmware-updater app. On Ubuntu, the drivers can be installed with dpkg -i and the appropriate (32-bit or 64-bit) deb filename. The archive contains debs, rpms, and tarballs for various distros. The drivers are available at the support page under the not-entirely-obvious name "Desktop Video for Linux". See the Connection Diagrams on the support page linked above. The HDMI slot should be wired to match this. They aren't labelled, but the input port is the one closest to the ePCI connector (e.g. There is an input port and an output port. The HDMI inputs are on a separate slot, connected to the card via HDMI cables. The card has a plethora of adapters for various types of video input. The manual can be found at the card's support page (I don't want to post a link directly to the manual in case they issue a new version and the URL changes). How this impacts Project Eideticker is unknown but a function of exactly what analyses we want to perform. exactly a 720-pixel high screen, a cropped/bordered output, or the ability to treat the HDMI output as the primary output so Firefox can render at exactly 720p). The only potentially perfect solution with this card would a device that outputs full RGB at 720p and does not do any scaling (e.g. What this means: it's almost impossible to get a pixel-perfect capture of a device with this card. Unfortunately neither of these limitations were apparent in their marketing materials we had to contact support to find out. Supposedly capturing at 720p is possible with 10-bit RGB, but not 8-bit RGB, for reasons unknown (perhaps due to the fact that the 10-bit formats use their own codecs). Capturing at 1080p50 and up can only be done at YUV 4:2:2, i.e., full 8-bit RGB is not possible.Unlike many TVs, the cards will not crop or add border to output that is larger or smaller than the standard it just won't capture at all. The important part here is that the output must be at a standard resolution, e.g. This means HDMI 720p and 1080p at standard refresh rates and a handful of other standards.
