需要缓存完一整个视频才能播放

[06110902002]

假设文件大小有100mb ，需要将这100mb缓存完才能播放，缓存一部分时 为啥不能播放？求解

[JeffMony]

贴一个例子，我来看下

[06110902002]

测试文件：
https://static-dev.nio.com/dc-operation/2022/11/16/g5sX1zY2BcfjORwH.mp4
http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear1/prog_index.m3u8

复现步骤：
1.先看一遍上述文件，不需要看完，看10秒即可，这里能在本地路径看到缓存了一部分文件如图：

2.关闭网络退出，重启之后再播放，不停的打印日志：
