Ah, I understand now.

Yes, the decklink device is currently the only SDI device which is supported by libavdevice.  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.

Would love to see more SDI devices supported and potentially interested in adding such support myself if we can find good candidates.  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).
