View Source Membrane.AAC.Parser (Membrane AAC plugin v0.12.1)

Parser for Advanced Audio Codec.

Supports both plain and ADTS-encapsulated output (configured by out_encapsulation). Input with encapsulation :none is supported, but correct AAC caps need to be supplied with the stream.

Adds sample rate based timestamp to metadata if absent.
