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 xcbgrab 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.
