Hi Thilo,

I am am working on  streaming FaceTime HD Camera with ffmpeg on OSX 10.8. I am getting the video but there is no audio input. I was referred to this link by a ffmpeg user and I think this will help my efforts. Can you please let me know how to install the patches and what is the command line I need to use to test. Please note that I am not expert user and I might need a bit of guidance from you on installing the patches.

Currently I use the below commands.

To find the devices attached

> ffmpeg -f avfoundation -list_devices true -i ""

The output I get is
[AVFoundation input device @ 0x7f9ff9c14ae0] AVFoundation video devices:
[AVFoundation input device @ 0x7f9ff9c14ae0] [0] FaceTime HD Camera
: Input/output error

To record from camera

>ffmpeg -f avfoundation -i "0" out.mp4

Looking forward for your earliest response.
