* This avdevice decoder can capture audio from an ALSA (Advanced

*
* The filename parameter is the name of an ALSA PCM device capable of
* capture, for example "default" or "plughw:1"; see the ALSA documentation
* for naming conventions. The empty string is equivalent to "default".
*
* The capture period is set to the lower value available for the device,
* which gives a low latency suitable for real-time capture.
*
* The PTS are an Unix time in microsecond.
*
* Due to a bug in the ALSA library
* (https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4308), this
* decoder does not work with certain ALSA plugins, especially the dsnoop
* plugin.

/**

* Special devices muxing/demuxing library.
*
* 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 xcbgrab 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.

* - channels: supported number of channels.

* - channel_layout: supported channel layouts.
* type: AV_OPT_TYPE_INT64
* - Capabilities valid for video devices:
* - pixel_format: supported pixel formats.

* - fps: supported fps values
* type: AV_OPT_TYPE_RATIONAL
