Demo

Useage

Install npm Package

npm install ffcreatorlite --save

Note: To run the preceding commands, Node.js and npm must be installed.

Node.js

const { FFCreatorCenter, FFScene, FFImage, FFText, FFCreator } = require('ffcreatorlite');

// create creator instance
const creator = new FFCreator({
  cacheDir,
  outputDir,
  width: 600,
  height: 400,
  log: true,
});

// create FFScene
const scene1 = new FFScene();
const scene2 = new FFScene();
scene1.setBgColor('#ff0000');
scene2.setBgColor('#b33771');

// scene1
const fbg = new FFImage({ path: bg1 });
scene1.addChild(fbg);

const fimg1 = new FFImage({ path: img1, x: 300, y: 60 });
fimg1.addEffect('moveInRight', 1.5, 1.2);
scene1.addChild(fimg1);

const text = new FFText({ text: '这是第一屏', font, x: 100, y: 100 });
text.setColor('#ffffff');
text.setBackgroundColor('#000000');
text.addEffect('fadeIn', 1, 1);
scene1.addChild(text);

scene1.setDuration(8);
creator.addChild(scene1);

// scene2
const fbg2 = new FFImage({ path: bg2 });
scene2.addChild(fbg2);
// logo
const flogo = new FFImage({ path: logo, x: 100, y: 100 });
flogo.addEffect('moveInUpBack', 1.2, 0.3);
scene2.addChild(flogo);

scene2.setDuration(4);
creator.addChild(scene2);

creator.addAudio(audio);
creator.start();

creator.on('progress', e => {
  console.log(colors.yellow(`FFCreatorLite progress: ${(e.percent * 100) >> 0}%`));
});

creator.on('complete', e => {
  console.log(
    colors.magenta(`FFCreatorLite completed: \n USEAGE: ${e.useage} \n PATH: ${e.output} `),
  );
});

About Transition

The latest version of ffcreatorlite already supports scene transition animation, which means you can use it to make cool effects like ffcreator.

Of course you need to install 4.3.0 above version of ffmpeg. Because here is the Xfade filter to achieve Animation.

usage

// https://trac.ffmpeg.org/wiki/Xfade
scene.setTransition('diagtl', 1.5);

fade (default)	fadeblack	fadewhite	distance
wipeleft	wiperight	wipeup	wipedown
slideleft	slideright	slideup	slidedown
smoothleft	smoothright	smoothup	smoothdown
rectcrop	circlecrop	circleclose	circleopen
horzclose	horzopen	vertclose	vertopen
diagbl	diagbr	diagtl	diagtr
hlslice	hrslice	vuslice	vdslice
dissolve	pixelize	radial	hblur
wipetl	wipetr	wipebl	wipebr
fadegrays	squeezev	squeezeh

About FFCreator

FFCreator is not an enhanced version of FFCreatorLite, in fact the two implementation principles are completely different. When you need to process a lot of video without special cool transition animation, FFCreatorLite may be a better choice.

Principle difference

• FFCreator uses opengl to process graphics rendering and shader post-processing to generate transition effects, and finally uses FFmpeg to synthesize the video.
• FFCreatorLite completely uses FFmpeg filters and other effects, splicing FFmpeg commands to generate animations and videos.

FFCreatorLite has 70% of the functions of FFCreator, but in some cases the processing speed is faster and the installation is extremely simple. So please choose which version of the library to use according to the actual usage.

The difference between registration points

The default registration point of FFCreatorLite is the upper left corner and cannot be modified, while the default registration point of FFCreator is the center and can be modified.

Installation

FFCreatorLite depends on FFmpeg, so you need to install FFmpeg

FFCreatorLite depends on FFmpeg>=0.9 and above. Please set FFmpeg as a global variable, otherwise you need to use setFFmpegPath to add FFmpeg native path. (The ffmpeg for windows users is probably not in your %PATH, so you must set %FFMPEG_PATH)

FFCreator.setFFmpegPath('...');

Of course, you can also compile ffmpeg on your machine, please see https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu.
