@type t() :: %Membrane.H26x.AccessUnit{
  keyframe?: boolean(),
  nalus: [Membrane.H26x.NALu.t()],
  nalus_payloads: [binary()],
  timestamps: Membrane.H26x.NALu.timestamps()
}

A type defining the structure of a single access unit produced by the parsing engine.

In the structure there are following fields:

• nalus - the list of logically associated NAL units making up the access unit.
• nalus_payloads - the payloads of the NALus (in the same order), prefixed for the output stream structure and ready to be output.
• timestamps - the {pts, dts} of the access unit - taken from its first VCL NALu or generated by the parsing engine ({nil, nil} if neither is available).
• keyframe? - whether the access unit contains a keyframe.
