@ -58,28 +58,30 @@ AVFoundation input device.
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>}.
