# 常见问题
## HLS 标准录制模式和原始录制模式有什么区别？
| | 标准录制模式 | 原始录制模式 |
| --- | --- | --- |
| ffmpeg | 需要 | 不需要 |
| 资源占用 | 较多 | 较少 |
| 稳定性 | 比较差 | 比较好 |
| 录播文件 | 一个 flv 文件 | 很多片段文件 |
| 录播信息 | 包含在 flv 文件里 | 单独保存为一个文件 (index.meta.json) |
| 播放器支持 | 几乎全部播放器都支持 flv | 支持 m3u8 的播放器很少 (VLC、dandanplay) |
| 自动分割文件 | 支持 | 不支持 |
| 手动分割文件 | 支持 | 不支持 |
| 自动转 mp4 | 支持 | 支持 |
## 如何终止程序？
