32  * @{
33  * Libavdevice is a complementary library to @ref libavf "libavformat". It
34  * provides various "special" platform-specific muxers and demuxers, e.g. for
35  * grabbing devices, audio capture and playback etc. As a consequence, the
36  * (de)muxers in libavdevice are of the AVFMT_NOFILE type (they use their own
37  * I/O functions). The filename passed to avformat_open_input() often does not
38  * refer to an actually existing file, but has some special device-specific
39  * meaning - e.g. for x11grab it is the display name.
40  *
41  * To use libavdevice, simply call avdevice_register_all() to register all
42  * compiled muxers and demuxers. They all use standard libavformat API.
