AVFoundation is the currently recommended framework by Apple for streamgrabbing on OSX >= 10.7 as well as on iOS.
The older QTKit framework has been marked deprecated since OSX version 10.7.
-The filename passed as input is parsed to contain either a device name or index.
-The device index can also be given by using -video_device_index.
+The filename passed as input is parsed to contain two input streams seperated by ":".
+The first stream select the video input while the latter selects the audio input @option{"<video>:<audio>"}.
+Each stream can either be specified by the device name or the index.
+The device index can also be given by using @option{-video_device_index <index>} and/or @option{-audio_device_index <index>}, respectively.
A given device index will override any given device name.
-If the desired device consists of numbers only, use -video_device_index to identify it.
-The default device will be chosen if an empty string or the device name "default" is given.
-The available devices can be enumerated by using -list_devices.
-The pixel format can be set using -pixel_format.
+If the desired device consists of numbers only, use the device index option to identify it.
+The default device will be chosen if an empty string or the device name @code{default} is given.
+The available devices can be enumerated by using @option{-list_devices true}.
+The pixel format can be set using @option{-pixel_format <format>}.
