Any suggestions? Also it appears (from ffmpeg configuration info) that this API requires libc++. This will nominally limit support to OS X 10.9+. -- Ticket URL: <https://trac.macports.org/ticket/51377#comment:6> MacPorts <https://www.macports.org/> Ports system for OS X

In order to install support for declink, the BlackMagic DecLink SDK, must be installed. Normally this would be implemented as a separate port under MacPorts and become a dependency for ffmpeg. Unfortunately, although the DecLink SDK is nominally opensource, its availability for download is restricted by BlackMagic. In order to download the SDK, BlackMagic requires the downloader to register their email address and formally agree to their licensing agreement. This doesn't restrict an individual from downloading the SDK and building ffmpeg with declink support for his own use, but makes it impractical to construct a port that can download the SDK on demand as MacPorts normally does. When I get some more time, I'll try building a version of ffmpeg with declink support using a manual download and, if successful, will publish a HOWTO on the MacPorts wiki so you can do it for yourself. I don't have access to the BlackMagic hardware so I'll need your help with testing. -- Ticket URL: <https://trac.macports.org/ticket/51377#comment:7> MacPorts <https://www.macports.org/> Ports system for OS X
