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