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