MEMBERS

byte_offset

Byte offset in ring buffer to DSP

copied_total

Total number of bytes copied from/to ring buffer to/by DSP

pcm_frames

Frames decoded or encoded by DSP. This field will evolve by large steps and should only be used to monitor encoding/decoding progress. It shall not be used for timing estimates.

pcm_io_frames

Frames rendered or received by DSP into a mixer or an audio output/input. This field should be used for A/V sync or time estimates.
