Class Compiler

This class is responsible for creating the command from multiple fragments. These fragments can be passed to it's constructor, or to it's Compiler.compile method.

const input = new Input( 'movie.mkv' );

const filter = new Filter( input.select( 'v' ), 'scale', { width: 1080, height: 720 } );

const output = new Output( 'movie.mp4', [ '-map', filter, '-map', input.select( 'a' ) ] );

const compiler = new Compiler( output );

// Any aditional fragments can be passed on to the compile method
compiler.compile( output );

Once all necessary fragments are compiled, you can obtain the CommandOptions as a string through CommandOptions.toString or an array of strings through CommandOptions.toArray

compiler.command.toString();
compiler.command.toArray();

A compiler can be cloned at any time. This is useful when you want to create multiple, similar commands, so you don't have to recompile every fragment, but can compile them first, and then clone the compiler as many times as necessary.
