# `FFix.Graph.StreamRef`
[🔗](https://github.com/akash-akya/ffix/blob/v0.2.0/lib/ffix/graph/stream_ref.ex#L1)

A selected input stream or the result of a filter.

Obtain a stream with an indexed helper such as `FFix.video/3`, a `FFix.Filter`
function, or `FFix.Graph.export/2`. Pass it to another filter, an encoder, or
an output. These functions manage the reference for you.

A stream retrieved from a graph retains the graph's other branches. See
`FFix.Graph` for keeping them connected, and `FFix.Selection` for output
queries that may match several tracks.

# `media`

```elixir
@type media() :: :audio | :video | :subtitle | :data | :attachment | :unknown
```

# `t`

```elixir
@opaque t()
```
