Public Methods
void OutputPipelineImpl (const PipelineConfig & config, const VolumeCurve & volume_curve, EffectsLoaderV2 * effects_loader_v2, uint32_t max_block_size_frames, TimelineFunction ref_time_to_frac_presentation_frame, std::shared_ptr<Clock> audio_clock, Mixer::Resampler sampler)Creates an |OutputPipeline| based on the specification in |config|. The pipeline will
ultimately produce output frames via |ReadLock| in the |output_format| requested.
|max_block_size_frames| is the largest contiguous region that may be returned from
|ReadLock|. If a caller requests a frame region of more that |max_block_size_frames|, then
the pipeline will truncate this to only |max_block_size_frames| and the caller will have to
call |ReadLock| again to mix the subsequent frames.
|ref_clock_to_fractional_frame| is a timeline function that will compute the output frame
number (in fixed point format with 13 bits of fractional precision) based on a reference
timestamp.
The |sampler| is optionally used to select the type of sampler to be used when joining
mix stages together.
