Membrane Element: FFmpeg SWResample v0.1.0 Membrane.Element.FFmpeg.SWResample.Converter View Source

This element performs audio conversion/resampling/channel mixing, using SWResample module of FFmpeg library.

Types

t()

Struct containing options for Membrane.Element.FFmpeg.SWResample.Converter

  • sink_caps: Audio caps for sink pad (input). If set to nil (default value), caps are assumed to be received from :sink. If explicitly set to some caps, they cannot be changed by caps received from :sink.
  • source_caps: Audio caps for souce pad (output)
  • frames_per_buffer: Assumed number of raw audio frames in each buffer. Used when converting demand from buffers into bytes

Functions

Returns all known sink pads for Membrane.Element.FFmpeg.SWResample.Converter

Returns all known source pads for Membrane.Element.FFmpeg.SWResample.Converter

Returns description of options available for this module
