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).
The President of AJA has publicly stated an intent to add an open license to their SDK, https://twitter.com/ajaprez/status/910100436224499713 <https://twitter.com/ajaprez/status/910100436224499713>. I’m glad to hear that handling other VANC data is in the works, I’m particularly interested in VITC and EIA-608 with inputs.
