# `Membrane.H26x.AccessUnit`
[🔗](https://github.com/membraneframework/membrane_h26x_plugin/blob/v0.11.2/lib/membrane_h26x_plugin/access_unit.ex#L1)

A module defining a struct representing a single access unit.

# `t`

```elixir
@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.
