遇到同样类似问题。用的示例代码（下面相关路径已经配置好，且对应目录有对应文件，文件来自于本项目examples下的assets目录）。cache里有scene1.mp4和scene2.mp4生成，但output下没看到真正生成的结果文件。另外，只是第一次cache可以生成，删掉cache后，再次运行就不再生成scene1.mp4和scene2.mp4了

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

应该需要安装升级ffmpeg版本，可参考下文
https://linuxize.com/post/how-to-install-ffmpeg-on-centos-7/
升级到3.x版本以上
