Membrane H265 plugin v0.4.0

View Source Membrane.H265.Parser.NALuSplitter (Membrane H265 plugin v0.4.0)

A module with functions responsible for splitting the h265 stream into the NAL units.

The splitting is based on "Annex B" of the "ITU-T Rec. H.265 (08/2021)".

Link to this section Summary

Types

t()

A structure holding the state of the NALu splitter.

Functions

new(input_stream_structure \\ :annexb, intial_binary \\ <<>>)

Returns a structure holding a NALu splitter state.

split(payload, assume_nalu_aligned \\ false, state)

Splits the binary into NALus sequence.

new(Membrane.H265.Parser.stream_structure(), binary()) :: t()

Returns a structure holding a NALu splitter state.

By default, the inner unparsed_payload of the state is clean. However, there is a possibility to set that unparsed_payload to a given binary, provided as an argument of the new/1 function.

Specs

split(payload :: binary(), assume_nalu_aligned :: boolean(), state :: t()) ::
  {[binary()], t()}

Splits the binary into NALus sequence.

Takes a binary h265 stream as an input and produces a list of binaries, where each binary is a complete NALu that can be passed to the Membrane.H265.Parser.NALuParser.parse/2.
