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