Enumeration Type Documentation

SampleFormat

enum SampleFormat : std::uint8_t

strong

Sample formats available in playd.

This is the intersection of those sample formats available in the decoders and SDL.

Packed formats are those where each sample contains each audio channel, one packed after the other. Planar formats use separate runs of samples for each channel (each channel has its own sample plane). For the most part, playd deals in the former, resampling instances of the latter.

REMEMBER: changes here will require changes in lookup tables in both sample_formats.cpp and audio_sink.cpp.
