Membrane element that decodes video in H264 format. It is backed by decoder from FFmpeg.

The element expects the data for each frame (Access Unit) to be received in a separate buffer, so the parser (Membrane.H264.Parser) may be required in a pipeline before decoder (e.g. when input is read from Membrane.File.Source).

Element options

Passed via struct Membrane.H264.FFmpeg.Decoder.t/0

• use_shm?

  boolean()

  Default value: false
  If true, native decoder will use shared memory (via Shmex.t/0) for storing frames
