some problems

hi there ara some problems in using video cache。
1.if device has network ,just setLooping(true) , it lead to the use of network also
2.readSourceAsync this method will cause concurrency problems。 its like lseek failed: EBADF (Bad file number) and so on。because if that cache file was still being write while another thread attempted to access it, an IOException would be thrown
3.sendto failed: ECONNRESET (Connection reset by peer) this problem I didn't resolve it， do u have any idea?
any way， thank u your shared
Best regard!
