|

|
*
|
||||||
|
* Audio resampling, sample format conversion and mixing library.
|
||||||
|
*
|
||||||
|
* 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().
