Node Fluent Ffmpeg

node-fluent-ffmpeg 是一个 FFmpeg 的 Node.js 包装器，为执行媒体命令和处理文件提供了流畅的接口。它充当进程管理器，处理外部 FFmpeg 二进制文件的生命周期，通过 ffprobe 实现程序化媒体转码、视频缩略图生成和元数据提取。

该库通过一个将 JavaScript 方法调用转换为命令行参数的命令构建器脱颖而出。它具有用于跟踪已处理帧和吞吐量的事件驱动进度监控功能，以及将处理后的媒体数据直接路由到可写流以进行实时处理的能力。

该项目涵盖了广泛的媒体处理功能，包括用于音频和视频属性的编码配置、用于视觉和音频效果的复杂滤镜图定义，以及用于连接多个源的输入管理。它还包括用于探测媒体容器和流以检索技术元数据的工具。
