Membrane.H264.FFmpeg.Decoder (Membrane H264 FFmpeg plugin v0.15.0) View Source

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.FFmpeg.Parser) may be required in a pipeline before decoder (e.g. when input is read from Membrane.File.Source).
