Hi Roger, Thanks for your response. I tried to use it as input but still I could not get it to work. Please see below:
Test#1- In this I used -i "0" and the terminal got frozen after I ran the command. I had to force quit the terminal. However the FaceTime camera light was on when I ran the command but nothing was captured. Command and the output is given below. $ ffmpeg -f avfoundation -i "0" -r 29.97 -y out.mov ffmpeg version 2.4.git Copyright (c) 2000-2014 the FFmpeg developers built on Sep 17 2014 18:11:13 with Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn) configuration: --prefix=/usr/local/ffmpegavpatch --extra-cflags=-I/usr/local/include --extra-ldflags=-L/usr/local/lib --enable-shared --enable-pthreads --enable-gpl --enable-version3 --enable-nonfree --enable-hardcoded-tables --enable-avresample --enable-vda --cc=clang --host-cflags= --host-ldflags= --enable-libx264 --enable-libfaac --enable-libmp3lame --enable-libxvid --enable-libfreetype --enable-libtheora --enable-libvorbis --enable-libvpx --enable-librtmp --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvo-aacenc --enable-libass --enable-ffplay --enable-libspeex --enable-libschroedinger --enable-libfdk-aac --enable-libopus --enable-frei0r --enable-libopenjpeg --disable-decoder=jpeg2000 --extra-cflags='-I/usr/local/Cellar/openjpeg/1.5.1_1/include/openjpeg-1.5 ' libavutil 54. 7.100 / 54. 7.100 libavcodec 56. 1.100 / 56. 1.100 libavformat 56. 4.102 / 56. 4.102 libavdevice 56. 0.100 / 56. 0.100 libavfilter 5. 1.101 / 5. 1.101 libavresample 2. 1. 0 / 2. 1. 0 libswscale 3. 0.100 / 3. 0.100 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 0.100 / 53. 0.100 (Terminal was frozen and no output messages seen in the terminal) Test#2 In this I tried to specify audio and video inputs separately as I do in Windows but I got the error message below. $ ffmpeg -f avfoundation -i video="FaceTime HD Camera":audio="Built-in Microphone" -r 29.97 -y out.mov configuration: --prefix=/usr/local/ffmpegavpatch --extra-cflags=-I/usr/local/include --extra-ldflags=-L/usr/local/lib --enable-shared --enable-pthreads --enable-gpl --enable-version3 --enable-nonfree --enable-hardcoded-tables --enable-avresample --enable-vda --cc=clang --host-cflags= --host-ldflags= --enable-libx264 --enable-libfaac --enable-libmp3lame --enable-libxvid --enable-libfreetype --enable-libtheora --enable-libvorbis --enable-libvpx --enable-librtmp --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvo-aacenc --enable-libass --enable-ffplay --enable-libspeex --enable-libschroedinger --enable-libfdk-aac --enable-libopus --enable-frei0r --enable-libopenjpeg --disable-decoder=jpeg2000 --extra-cflags='-I/usr/local/Cellar/openjpeg/1.5.1_1/include/openjpeg-1.5 ' libavutil 54. 7.100 / 54. 7.100 libavcodec 56. 1.100 / 56. 1.100 libavformat 56. 4.102 / 56. 4.102 libavdevice 56. 0.100 / 56. 0.100 libavfilter 5. 1.101 / 5. 1.101 libavresample 2. 1. 0 / 2. 1. 0 libswscale 3. 0.100 / 3. 0.100 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 0.100 / 53. 0.100 [AVFoundation input device @ 0x7fc133c15700] Video device not found video=FaceTime HD Camera:audio=Built-in Microphone: Input/output error I also tried $ffmpeg -f avfoundation -i video="FaceTime HD Camera" -i audio="Built-in Microphone" -r 29.97 -y out.mov and I got the same error message as above.
