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 entry selects 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>}.
