Thanks again for your help. I’ve rebuilt ffmpeg and now I do see devices.
But I don’t know how to differentiate. From the output below it seems to me there’s only 1 device which very likely would be the built-in webcam of the macbook pro. Which, if that is the case, then my thunderbolt device isn’t being recognized. I do know that the capture device works, I can see it if I run the Flash Media Live Encoder application or the Media Express application that comes with the capture device. $ /usr/local/bin/ffmpeg -devices ffmpeg version N-73015-g8edc17b 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: --enable-nonfree --enable-gpl --enable-version3 --enable-postproc --enable-swscale --enable-avfilter --enable-libmp3lame --enable-libvorbis --enable-libtheora --enable-libfaac --enable-libxvid --enable-libx264 --enable-libvpx --enable-hardcoded-tables --enable-shared --enable-pthreads libavutil 54. 27.100 / 54. 27.100 libavcodec 56. 41.100 / 56. 41.100 libavformat 56. 37.100 / 56. 37.100 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 Devices: D. = Demuxing supported .E = Muxing supported -- D avfoundation AVFoundation input device D lavfi Libavfilter virtual input device D qtkit QTKit input device E sdl SDL output device > On Jun 20, 2015, at 4:12 AM, Moritz Barsnick <[email protected]> wrote: > > Hi Ricardo, > > On Fri, Jun 19, 2015 at 18:52:02 -0700, Ricardo Kleemann wrote: >> And tried the command -devices and I don’t understand the output.
