defmodule Membrane.MPEG.TS.Profiles do
@moduledoc """
Well-known stream profiles that combine stream_type, descriptors, and payload adapters.
Profiles provide a higher-level way to select or configure streams without
hiding the underlying PMT details. For example, `:opus_mpeg_ts` expands to
PES private data with an `Opus` registration descriptor and uses the Opus
MPEG-TS packetizer/depacketizer.
