  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.
