 # 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 |
