View Source Membrane.RTP.H265.FU (Membrane RTP H265 Plugin v0.5.2)

Module responsible for parsing H265 Fragmentation Unit.

Summary

Types

don()
t()

Functions

parse(data, seq_num, acc)

Parses H265 Fragmentation Unit

serialize(data, preferred_size)

Serialize H265 unit into list of FU payloads

Types

don()

@type don() :: nil | non_neg_integer()

t()

@type t() :: %Membrane.RTP.H265.FU{
  data: [binary()],
  don: don(),
  donl?: boolean(),
  last_seq_num: nil | non_neg_integer(),
  type: Membrane.RTP.H265.NAL.Header.type()
}

Functions

parse(data, seq_num, acc)

@spec parse(binary(), non_neg_integer(), t()) ::
  {:ok, {binary(), Membrane.RTP.H265.NAL.Header.type(), don()}}
  | {:error, :packet_malformed | :invalid_first_packet}
  | {:incomplete, t()}

Parses H265 Fragmentation Unit

If a packet that is being parsed is not considered last then a {:incomplete, t()} tuple will be returned. In case of last packet {:ok, {type, data, don}} tuple will be returned, where data is NAL Unit created by concatenating subsequent Fragmentation Units and don is the decoding order number of the NAL unit in case donl field is present in the packet.

serialize(data, preferred_size)

@spec serialize(binary(), pos_integer()) :: [binary()] | {:error, :unit_too_small}
