[FFmpeg-user] NSOSStatusErrorDomain Code=-12905

[Ari Black]

I have a Mac Mini running Mavericks (10.9.3) with a Logitech c270 USB
webcam. I downloaded the most recent archive of ffmpeg and configured
and made it:

./configure --prefix=/usr/local --extra-cflags="-I/usr/local/include"
--extra-ldflags="-L/usr/local/lib" --enable-libx264 --enable-gpl
make

Following the Mac OS X instructions from
https://trac.ffmpeg.org/wiki/How%20to%20capture%20a%20webcam%20input,
I'm running it from the compilation directory like so:

./ffmpeg -f avfoundation -list_devices true -i ""

But when I try ./ffmpeg -f avfoundation -i "" out.mpg I get this:
2014-05-24 13:47:01.561 ffmpeg[96367:3e03] ***

The light on the camera goes on but that error messages continues
forever unless I cancel the process. out.mpg is never created. I've
googled the error code and it seems to be related to the pixel format
but I've been unable to investigate further because I can't get
video4linux to compile on Mac OS X.

Can someone help me solve this?
