View Source Membrane.WAV.Serializer (Membrane WAV Plugin v0.7.0)
Element responsible for raw audio serialization to WAV format.
Creates WAV header (its description can be found with Membrane.WAV.Parser
) based on a format received in caps and puts it before audio samples. The element assumes that audio is in PCM format.
file length
and data length
fields can be calculated only after processing all samples, so
the serializer uses Membrane.File.SeekEvent
to supply them with proper values before the end
of stream. If your sink doesn't support seeking, set disable_seeking
option to true
and fix
the header using Membrane.WAV.Postprocessing
.
