View Source Membrane.MP4.Track (Membrane MP4 plugin v0.34.1)

A module defining a structure that represents an MPEG-4 track.

All new samples of a track must be stored in the structure first in order to build a sample table of a regular MP4 container. Samples that were stored can be flushed later in form of chunks.
