Multiplex example
This folder provides an example of multiplexing tracks from fragmented MP4 files.
The functions
combineInitSegments
combineMediaSegments
combines the tracks from two or more different init or media segments. The combined tracks get unique track names as specified using parameters. Note that they should start at 1 according to the file format specification.
In principle, the trex box data from the init segment may be needed when
generating media segments since that may contain default values. In practice,
for this specific case of just transfering tracks, it should work without
propagating the trex data.
The data is written to the combined mdat box track by track, so that there
is exactly one trun box for each track. Interleaving data into more trun
boxes should be possible by writing fractions of samples from the different
input files.
