View Source Membrane.FLAC.Parser.Engine (Membrane FLAC plugin v0.12.0)

Stateful parser based on FLAC format specification available here

The parser outputs:

Membrane.FLAC
Membrane.Buffer with "fLaC" - the FLAC stream marker in ASCII
At least one Membrane.Buffer with metadata block(s)
Membrane.Buffers containing one frame each, with decoded metadata from its header (as Membrane.FLAC.FrameMetadata struct)

The parsing is done by calling init/0 and than parse/2 with the data to parse. The last buffer can be obtained by calling flush/1

The parser returns a frame once it encounters a beginning of the next one since there's no other way to determine where the frame ends.

Link to this section Summary

state()

Opaque struct containing state of the parser.

flush(map)

Outputs the last buffer queued in parser. Should be called afer providing all data to the parser.

Returns an initialized parser state

Parses FLAC stream, splitting it into Membrane.Buffers and providing format.

(opaque)

@opaque state()

Opaque struct containing state of the parser.

@spec flush(state()) :: {:ok, Membrane.Buffer.t()}

Outputs the last buffer queued in parser. Should be called afer providing all data to the parser.

@spec init(boolean()) :: state()

Returns an initialized parser state

@spec parse(binary(), state()) ::
  {:ok, [Membrane.StreamFormat.t() | Membrane.Buffer.t()], state()}
  | {:error, any()}

Parses FLAC stream, splitting it into Membrane.Buffers and providing format.

See moduledoc (Membrane.FLAC.Parser.Engine) for more info

The call without state provided is an equivalent of using init/0 as state
