Membrane MP4 plugin
v0.24.1

View Source Membrane.MP4.Demuxer.ISOM (Membrane MP4 plugin v0.24.1)

A Membrane Element for demuxing an MP4.

The MP4 must have fast start enabled, i.e. the moov box must precede the mdat box. Once the Demuxer identifies the tracks in the MP4, new_tracks_t/0 notification is sent for each of the tracks.

All the tracks in the MP4 must have a corresponding output pad linked (Pad.ref(:output, track_id)).
