Demo

Useage

Install npm Package

npm install ffcreator --save

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

Node.js

const { FFScene, FFText, FFVideo, FFAlbum, FFImage, FFCreator } = require("ffcreator");

// Create FFCreator instance
const creator = new FFCreator({
    cacheDir,
    outputDir,
    width: 800,
    height: 450
});

// Create scene
const scene = new FFScene();
scene.setBgColor("#ffcc22");
scene.setDuration(6);
scene.setTransition("GridFlip", 2);
creator.addChild(scene);

// Create Image and add animation effect
const image = new FFImage({ path: path.join(__dirname, "../assets/01.jpg") });
image.addEffect("moveInUp", 1, 1);
image.addEffect("fadeOutDown", 1, 4);
scene.addChild(image);

// Create Text
const text = new FFText({ text: "hello 你好", x: 400, y: 300 });
text.setColor("#ffffff");
text.setBackgroundColor("#000000");
text.addEffect("fadeIn", 1, 1);
scene.addChild(text);

// Create a multi-photo Album
const album = new FFAlbum({
    list: [img1, img2, img3, img4],   // Picture collection for album
    x: 250,
    y: 300,
    width: 500,
    height: 300,
});
album.setTransition('zoomIn');      // Set album switching animation
album.setDuration(2.5);             // Set the stay time of a single sheet
album.setTransTime(1.5);            // Set the duration of a single animation
scene.addChild(album);

// Create Video
const video = new FFVideo({ path, x: 300, y: 50, width: 300, height: 200 });
video.addEffect("zoomIn", 1, 0);
scene.addChild(video);

creator.output(path.join(__dirname, "../output/example.mp4"));
creator.start();        // Start processing
creator.closeLog();     // Close log (including perf)

creator.on('start', () => {
    console.log(`FFCreator start`);
});
creator.on('error', e => {
    console.log(`FFCreator error: ${JSON.stringify(e)}`);
});
creator.on('progress', e => {
    console.log(colors.yellow(`FFCreator progress: ${e.state} ${(e.percent * 100) >> 0}%`));
});
creator.on('complete', e => {
    console.log(colors.magenta(`FFCreator completed: \n USEAGE: ${e.useage} \n PATH: ${e.output} `));
});

Some great open source projects developed based on FFCreator and excellent tutorial articles here

About Audio

Sound is the soul of a video. FFCreator supports multiple ways to add audio. You can not only add global background music, but also set your own voice or soundtrack for each individual scene.

• In FFVideo - Turn on video background music (default off).

const video = new FFVideo({ path, x: 100, y: 150, width: 500, height: 350 });
video.setTimes('00:00:18', '00:00:33');
video.setAudio(true); // Turn on

• Add a global background audio.

const creator = new FFCreator({
  cacheDir,
  outputDir,
  audio: path, // background audio
});

// or
creator.addAudio({ path, loop, start });

• Add your own separate music for each scene.

scene.addAudio(path);
// or
scene.addAudio({ path, loop, start });

About Cache

FFCreator3.0+ uses node Stream for data caching. The original version frees up disk space and further improves the speed.

Stream settings

• By setting parallel (or frames) to modify the number of video frames for a single parallel rendering.

  Note: This should be set reasonably according to the actual configuration of your machine, not that the larger the value, the better.

parallel: 10,

• Set highWaterMark, you can learn about the highWaterMark water mark from here.

highWaterMark: '6mb',

• Set the pool to turn on or off the object pool mode.

pool: true,

About FFmpeg

At the initiation of your project, you can ensure seamless operation by configuring the path for ffmpeg using either FFCreator.setFFPath(), setFFmpegPath(path: string), or setFFprobePath(path: string). This ensures that the project can access the necessary ffmpeg utilities for its execution. For more comprehensive ffmpeg configuration options, please refer to the configuration page.

Installation

1. Install node-canvas and headless-gl dependencies

If it is a computer with a display device, such as a personal pc computer with windows, Mac OSX system, or a server server with a graphics card or display device, you can skip this step without installing this dependency.

If you are using Centos, Redhat, Fedora system, you can use yum to install.

sudo yum install gcc-c++ cairo-devel pango-devel libjpeg-turbo-devel giflib-devel

InstallXvfb and Mesa

sudo yum install mesa-dri-drivers Xvfb libXi-devel libXinerama-devel libX11-devel

If you are using Debian, ubuntu system, you can use apt to install.

sudo apt-get install libcairo2-dev libjpeg-dev libpango1.0-dev libgif-dev build-essential g++
sudo apt-get install libgl1-mesa-dev xvfb libxi-dev libx11-dev

2. Because FFCreator depends on FFmpeg, you need to install a regular version of FFmpeg

• How to Install and Use FFmpeg on CentOS https://linuxize.com/post/how-to-install-ffmpeg-on-centos-7/
• How to Install FFmpeg on Debian https://linuxize.com/post/how-to-install-ffmpeg-on-debian-9/
• How to compiling from Source on Linux https://www.tecmint.com/install-ffmpeg-in-linux/

Start Up

If it is a computer with a display device, such as a personal pc computer or a server server with a graphics card or display device, start normally npm start

Otherwise, You must use the xvfb-run script command to start the program to use webgl under the Linux server

xvfb-run more detailed command parameters http://manpages.ubuntu.com/manpages/xenial/man1/xvfb-run.1.html

xvfb-run -s "-ac -screen 0 1280x1024x24" npm start

Questions

1. During installation warning missing package'xi'

No package 'xi'

foundgyp: Call to 'pkg-config --libs-only-l x11 xi xext' returned exit status 1 while in angle/src/angle.gyp. while loading dependencies of binding.gyp while trying to load binding.gyp

Solution

yum install libXi-devel libXinerama-devel libX11-devel

2. Start node app and prompt error message doesn't support WebGL....

Solution

The node app should be started as follows.

xvfb-run -s "-ac -screen 0 1280x1024x24" npm start

3. Npm install error ERR! command sh -c node-pre-gyp install --fallback-to-build

Solution

It may be caused by your node version. If it is nodev15, there will be this problem. https://github.com/Automattic/node-canvas/issues/1645 . Please use the stable version of node.js. For example, nodev14 (even version).
