Instalei o ffmpeg 0.8.5 no meu Mac OS X Lion 10.7.1 com Homebrew
brew install --use-gcc ffmpeg
É instalado sem nenhum erro. Mas agora, quando corro, fornece o seguinte -
dyld: Library not loaded: /usr/local/Cellar/ffmpeg/0.8.5/lib/libavdevice.dylib
Referenced from: /usr/local/bin/ffmpeg
Reason: Incompatible library version: ffmpeg requires version 53.0.0 or later, but libavdevice.dylib provides version 52.0.0
Trace/BPT trap: 5
