ai用ffmpeg+python实现视频转换ts并生成m3u8小工具

前言

这几天需要把本网站的视频放到服务器提供在线播放，直接用mp4格式的话，加载和快进都会比较慢，主要是流量用的比较多，把MP4视频切片成ts后就能节约流量也能提高播放速度，以后大家就不用去网盘享受那龟速的下载体验，也不用去开网盘会员了；当然我们还是会同步提供下载课程的入口。

说干就干

我们让AI基于 FFmpeg 和 Python 写的视频转换m3u8实用小工具，用于高效地将各种格式的视频转换为 TS 格式，同时生成对应的 M3U8 播放列表文件。该工具旨在简化视频处理过程，特别适用于需要快速部署 HLS（HTTP Live Streaming）视频流媒体的场景。

视频切片ts软件功能特点

1. 多格式支持
   • 支持常见的视频格式（如 MP4、MKV、AVI、MOV 等），能够轻松进行格式转换而无需复杂配置。
2. 高效处理
   • 借助 FFmpeg 的强大功能，该工具通过无编码方式直接切片视频为 TS 文件，避免重复编码导致的画质损失和处理速度下降。
3. 自动生成 M3U8 播放列表
   • 在将视频切片成 TS 文件的同时，自动生成对应的 M3U8 文件，方便用于流媒体播放。
4. 简单易用
   • 提供用户友好的界面（CLI 或 GUI），无需深入了解 FFmpeg 命令行，任何用户都能轻松上手。
5. 可配置性强
   • 支持自定义切片长度（例如每 10 秒生成一个 TS 文件），满足不同应用场景的需求。
