Membrane.LiveFramerateConverter

A Membrane element that drops or fills frames to produce a stable output framerate. Suited for realtime applications.

Installation

def deps do
  [
    {:membrane_live_framerate_converter_plugin, "~> 1.0"}
  ]
end

Stable Framerate Behavior

The converter maintains a fixed output cadence by mapping incoming buffers into regular time slots defined by the target framerate:

• If an incoming buffer is late for the current slot, it is dropped.
• If a slot arrives without input, behavior depends on stall_policy.

Stall Handling

When input stalls after playback has started:

• :duplicate duplicates the last received frame to preserve cadence.
• :halt stops output until new input arrives.

Notifications are emitted for drops, duplications, stalls, and resumes to make it easy to observe these edge cases in a pipeline.
