create_sampler_from_stream()

MAYAFLUX_API std::shared_ptr< Kriya::SamplingPipeline > MayaFlux::create_sampler_from_stream	(	std::shared_ptr< Kakshya::DynamicSoundStream >	stream,
		uint32_t	channel = 0,
		uint64_t	max_dur_ms = 0
	)

Construct a built SamplingPipeline from an existing DynamicSoundStream.

Allows multiple SamplingPipeline instances to share a single loaded stream, one per output channel, without re-reading the file. The stream is typically obtained from a previously created sampler via get_stream(), or loaded directly via get_io_manager()->load_audio_bounded().

auto ch0 = MayaFlux::create_sampler("res/audio.wav", 48000 * 5);
auto ch1 = MayaFlux::create_sampler_from_stream(ch0->get_stream(), 1);
auto ch2 = MayaFlux::create_sampler_from_stream(ch0->get_stream(), 2);

Parameters

stream	Loaded DynamicSoundStream to share.
channel	Output channel index (default: 0).
max_dur_ms	Optional maximum duration in milliseconds. 0 for infinite.

Returns

Built SamplingPipeline, or nullptr if stream is null.
