Hi Jimmy,
A few people are testing the Linux version of the Blackmagic DeckLink VIC
grabber code that's in Sumover SVN.
I've now checked in some minor mods to work with the MacOS X DeckLink API.
Although VIC's MacOS X DeckLink grabber code is almost identical to the Linux
version, the performance is much worse on the same machine, I need to
investigate why.
Hit Lab NZ VIC is based on a latter version of SVN VIC's DirectShow grabber
code that's been modified to support larger frame sizes. The SVN DirectShow
grabber code was intentionally limited to a max resolution of 720p (or it might
even be 576p for PAL signal and 480p for NTSC) but I can't remember without
look into the code.
I might get around to modifying VIC's native DeckLink grabber code to work with
the Windows DecLink API one day, the API isn't too different from the Linux and
Mac versions. The performance should hopefully also be better than using
DirectShow.
Cheers,
Doug

Last year, the HIT Lab in New Zealand was kind enough to knock an HD vic for
the HDMI interface. Now Nathan Gardiner has moved on and I was wondering if
there was anyone else there that can continue work on it. One major limitation
is that it will stream at a maximum of 128 Kbps. That's way too low for what we
need. Doesn't make much sense to use HD at 128 Kbps.
Is anyone picking up the work of Derek Piper and his AGVCR. I'm having some
issues where it doesn't seem to handle the HD streams and during playback, I'm
seeing some major artifacts and image break-up.
If anyone is working other HD solutions I am very interested in hearing
about it.
Thanks,
Jimmy
