View Source Membrane.WAV.Serializer (Membrane WAV Plugin v0.9.0)

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 stream_format 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.

  • disable_seeking

    boolean()

    Default value: false
    Whether the element should disable emitting Membrane.File.SeekEvent.

    The event is used to supply the WAV header with proper values before the end of stream. If your sink doesn't support it, you should set this option to true and use Membrane.WAV.Postprocessing to fix the header.
