 Summary of the bug:
 I use FFmpeg to capture video and audio from a Decklink card.
 I am building FFmpeg myself with the media-autobuild_suite
 (https://github.com/jb-alvarado/media-autobuild_suite).
 I keep old versions for myself for backup purposes. So long I did not have
 any issues using those builds for capturing from a Decklink card.
 But since recently I saw that the handling of the Decklink card seems to
 be broken. I could narrow it down (from my backups) to a timespan between
 2017-05-30 and 2017-06-16 where something changed that broke it. The old
 version (2017-05-30) does work, the newer ones, including the latest, do
 not work.
 I have attached the log files for the builds I had at hand to test.

 How to reproduce:
 {{{
 % ffmpeg -v 9 -loglevel 99 -f decklink -list_devices 1 -i dummy -report
 ffmpeg version N-86494-g18f09524f7 (and newer)
 built on 2017-06-16
 }}}
