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