I’ve got a whole pile of patches coming which add support for a variety of protocols for both capture and output (e.g. EIA-708, SCTE-104, AFD, SMPTE 2038, etc).  But today the decklink module is the only device supported.

The DVEO/linsys cards are largely obsolete and the AJA boards are significantly more expensive than any of BlackMagic’s cards.  If anyone has good experiences with other vendors I would like to hear about it (and there may be an opportunity to extend libavdevice to support another SDI vendor).

Bluefish has some very nice ($$$) SDI cards with Linux support. I
think their SDK also supports v4l2. Have never been able to get my
hands on one though.
