The Problem whith m3u8 cache

I found that AndroidVideoCache can cache the m3u8,because i found the cahe file in the disk,but,the player can not play the video,I do not know why? it is a AndroidVideoCache bug or the player's bug?

The report mentions AndroidVideoCache, m3u8 caching, a cached file on disk, and an unspecified video player, but names no source file or test. Start by reproducing the playback failure with the reported m3u8 setup and determine whether the cache output or the player is responsible. Done requires a reproducible case and a confirmed component to fix.
