6.3. Supported fields
A complex source string is limited to a set of well-defined field/value pairs, some of them mandatory, the
others optional.
6.3.1. Input file fields
These fields specify the media file(s) to be played. It is possible to compose a clip out of several essence
files, for example a video file and number of audio files. Normally, the file0 field will be sufficient to
define an input file that holds all the needed streams.

numbering. See field file0 for supported formats.
