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});

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
sudo yum install mesa-dri-drivers Xvfb libXi-devel libXinerama-devel libX11-devel
If you are using Debian, ʻubuntusystem, you can use ʻapt 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
