+== Mac ==
+
+Mac users can use the "qtkit" input device for grabbing integrated iSight cameras as well as cameras connected via USB or !FireWire.
+QTKit is available on Mac OS X 10.4 (Tiger) and later.
+
+ 
+=== QTKit ===
+
+To list the supported capture devices, connected to the machine:
+{{{
+ffmpeg -f qtkit -list_devices true -i ""
+}}}
+
+To use the default device which is usually the first device in the listing the user can either use an empty name string or "default":
+{{{
+ffmpeg -f qtkit -i "" out.mpg
+}}}
+or
+{{{
+ffmpeg -f qtkit -i "default" out.mpg
+}}}
+
+To use one of these devices for capturing the user has to specifiy either the name of the device or the index shown in the device listing.
+Abbreviations using just the beginning of the device name are possible. Thus, to capture form a device named "Integrated iSight-camera":
+{{{
+ffmpeg -f qtkit -i "Integrated" out.mpg
+}}}
+
+To use the device's index provide the index either as the input or use the -video_device_index option that will override any given input name:
+So
+{{{
+ffmpeg -f qtkit -i "2" out.mpg
+}}}
+and
+{{{
+ffmpeg -f qtkit -video_device_index 2 -i "default" out.mpg
+}}}
+will use the device with the index 2 ignoring the default device in the second case.
