@chapter Device Options@c man begin DEVICE OPTIONSThe libavdevice library provides the same interface aslibavformat. Namely, an input device is considered like a demuxer, andan output device like a muxer, and the interface and generic deviceoptions are the same provided by libavformat (see the ffmpeg-formatsmanual).In addition each input or output device may support so-called privateoptions, which are specific for that component.Options may be set by specifying -@var{option} @var{value} in theFFmpeg tools, or by setting the value explicitly in the device@code{AVFormatContext} options or using the @file{libavutil/opt.h} APIfor programmatic use.@c man end DEVICE OPTIONS
