-/**
- * @defgroup lavd 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 x11grab 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.

- *
- * List of capabilities that can be queried:
- *  - Capabilities valid for both audio and video devices:
- *    - codec:          supported audio/video codecs.
- *                      type: AV_OPT_TYPE_INT (AVCodecID value)
- *  - Capabilities valid for audio devices:
- *    - sample_format:  supported sample formats.
- *                      type: AV_OPT_TYPE_INT (AVSampleFormat value)
- *    - sample_rate:    supported sample rates.
- *                      type: AV_OPT_TYPE_INT
- *    - channels:       supported number of channels.
- *                      type: AV_OPT_TYPE_INT
- *    - channel_layout: supported channel layouts.
- *                      type: AV_OPT_TYPE_INT64
- *  - Capabilities valid for video devices:
- *    - pixel_format:   supported pixel formats.
- *                      type: AV_OPT_TYPE_INT (AVPixelFormat value)
- *    - window_size:    supported window sizes (describes size of the window size presented to the user).
- *                      type: AV_OPT_TYPE_IMAGE_SIZE
- *    - frame_size:     supported frame sizes (describes size of provided video frames).

- *    - fps:            supported fps values
- *                      type: AV_OPT_TYPE_RATIONAL
- *
- * Value of the capability may be set by user using av_opt_set() function
- * and AVDeviceCapabilitiesQuery object. Following queries will
- * limit results to the values matching already set capabilities.
- * For example, setting a codec may impact number of formats or fps values
- * returned during next query. Setting invalid value may limit results to zero.
- *

- * @code
- *  AVFormatContext *oc = NULL;
- *  AVDeviceCapabilitiesQuery *caps = NULL;

-/**
- * @defgroup lswr Libswresample
- * @{
- *
- * Libswresample (lswr) is a library that handles audio resampling, sample
- * format conversion and mixing.
- *
- * Interaction with lswr is done through SwrContext, which is
- * allocated with swr_alloc() or swr_alloc_set_opts(). It is opaque, so all parameters
- * must be set with the @ref avoptions API.
- *
- * The first thing you will need to do in order to use lswr is to allocate
- * SwrContext. This can be done with swr_alloc() or swr_alloc_set_opts(). If you
- * are using the former, you must set options through the @ref avoptions API.
- * The latter function provides the same feature, but it allows you to set some
- * common options in the same statement.
- *
- * For example the following code will setup conversion from planar float sample
- * format to interleaved signed 16-bit integer, downsampling from 48kHz to
- * 44.1kHz and downmixing from 5.1 channels to stereo (using the default mixing
- * matrix). This is using the swr_alloc() function.
- * @code
- * SwrContext *swr = swr_alloc();
- * av_opt_set_channel_layout(swr, "in_channel_layout",  AV_CH_LAYOUT_5POINT1, 0);
- * av_opt_set_channel_layout(swr, "out_channel_layout", AV_CH_LAYOUT_STEREO,  0);
- * av_opt_set_int(swr, "in_sample_rate",     48000,                0);
- * av_opt_set_int(swr, "out_sample_rate",    44100,                0);
- * av_opt_set_sample_fmt(swr, "in_sample_fmt",  AV_SAMPLE_FMT_FLTP, 0);
- * av_opt_set_sample_fmt(swr, "out_sample_fmt", AV_SAMPLE_FMT_S16,  0);
- * @endcode
- *
- * The same job can be done using swr_alloc_set_opts() as well:
- * @code
- * SwrContext *swr = swr_alloc_set_opts(NULL,  // we're allocating a new context
- *                       AV_CH_LAYOUT_STEREO,  // out_ch_layout
- *                       AV_SAMPLE_FMT_S16,    // out_sample_fmt
- *                       44100,                // out_sample_rate
- *                       AV_CH_LAYOUT_5POINT1, // in_ch_layout
- *                       AV_SAMPLE_FMT_FLTP,   // in_sample_fmt
- *                       48000,                // in_sample_rate
- *                       0,                    // log_offset
- *                       NULL);                // log_ctx
- * @endcode
- *
- * Once all values have been set, it must be initialized with swr_init(). If
- * you need to change the conversion parameters, you can change the parameters
- * using @ref AVOptions, as described above in the first example; or by using
- * swr_alloc_set_opts(), but with the first argument the allocated context.
- * You must then call swr_init() again.
- *
- * The conversion itself is done by repeatedly calling swr_convert().
- * Note that the samples may get buffered in swr if you provide insufficient
- * output space or if sample rate conversion is done, which requires "future"
- * samples. Samples that do not require future input can be retrieved at any
- * time by using swr_convert() (in_count can be set to 0).
- * At the end of conversion the resampling buffer can be flushed by calling
- * swr_convert() with NULL in and 0 in_count.
- *
- * The samples used in the conversion process can be managed with the libavutil
- * @ref lavu_sampmanip "samples manipulation" API, including av_samples_alloc()
- * function used in the following example.
- *
- * The delay between input and output, can at any time be found by using
- * swr_get_delay().
- *
- * The following code demonstrates the conversion loop assuming the parameters
- * from above and caller-defined functions get_input() and handle_output():
- * @code
- * uint8_t **input;
- * int in_samples;
- *
- * while (get_input(&input, &in_samples)) {
- *     uint8_t *output;
- *     int out_samples = av_rescale_rnd(swr_get_delay(swr, 48000) +
- *                                      in_samples, 44100, 48000, AV_ROUND_UP);
- *     av_samples_alloc(&output, NULL, 2, out_samples,
- *                      AV_SAMPLE_FMT_S16, 0);
- *     out_samples = swr_convert(swr, &output, out_samples,
- *                                      input, in_samples);
- *     handle_output(output, out_samples);
- *     av_freep(&output);
- * }
- * @endcode
- *
- * When the conversion is finished, the conversion
- * context and everything associated with it must be freed with swr_free().
- * A swr_close() function is also available, but it exists mainly for
- * compatibility with libavresample, and is not required to be called.
- *
- * There will be no memory leak if the data is not completely flushed before
- * swr_free().

- * Input and output AVFrames must have channel_layout, sample_rate and format set.

- * If the output AVFrame does not have the data pointers allocated the nb_samples
- * field will be set using av_frame_get_buffer()
- * is called to allocate the frame.
- *
- * The output AVFrame can be NULL or have fewer allocated samples than required.
- * In this case, any remaining samples not written to the output will be added
- * to an internal FIFO buffer, to be returned at the next call to this function
- * or to swr_convert().
- *
- * If converting sample rate, there may be data remaining in the internal
- * resampling delay buffer. swr_get_delay() tells the number of
- * remaining samples. To get this data as output, call this function or
- * swr_convert() with NULL input.
- *
- * If the SwrContext configuration does not match the output and
- * input AVFrame settings the conversion does not take place and depending on
- * which AVFrame is not matching AVERROR_OUTPUT_CHANGED, AVERROR_INPUT_CHANGED
- * or the result of a bitwise-OR of them is returned.
