These commands are now all working and I get the set of formats supported. My problem now is that ffmpeg (and even ffplay) all they show is the multi-colored vertical bars. If I run BMD Media Express, however, I see the video coming from the camera. So something seems quite strange in how ffmpeg is acquiring the source. I get the error of “No input signal detected” $ ffmpeg -f decklink -i 'UltraStudio Mini Recorder@10' output.mov ffmpeg version N-73104-g7604358 Copyright (c) 2000-2015 the FFmpeg developers built with Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn) configuration: --prefix=/usr/local --enable-gpl --enable-nonfree --enable-ffplay --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-decklink --extra-cflags=-I/Users/ptl/blackmagicsdk/Mac/include --extra-ldflags=-L/Users/ptl/blackmagicsdk/Mac/include libavutil 54. 27.100 / 54. 27.100 libavcodec 56. 44.100 / 56. 44.100 libavformat 56. 38.100 / 56. 38.100 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 17.100 / 5. 17.100 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 2.100 / 1. 2.100 libpostproc 53. 3.100 / 53. 3.100 [decklink @ 0x7fba09800000] Found Decklink mode 1920 x 1080 with rate 30.00 [decklink @ 0x7fba09800000] Frame received (#1) - No input signal detected - Frames dropped 1 Guessed Channel Layout for Input Stream #0.0 : stereo Input #0, decklink, from 'UltraStudio Mini Recorder@10': Duration: N/A, start: 0.000000, bitrate: 1536 kb/s Stream #0:0: Audio: pcm_s16le, 48000 Hz, 2 channels, s16, 1536 kb/s Stream #0:1: Video: rawvideo (UYVY / 0x59565955), uyvy422, 1920x1080, -5 kb/s, 30 tbr, 1000k tbn, 30 tbc No pixel format specified, yuv422p for H.264 encoding chosen.
