mplayer /home/test.mp3
MPlayer interrupted by signal 11 in module: decode_audio
- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
won't help unless you provide this information when reporting a possible bug.
如果不使用RTL8723，貌似就没这个问题，不知道大家是否遇到过

是不是供电不足？
电源是5V1A的，发现使用WIFI会导致内存占用率较高，只剩余8M，不知道是不是这个原因
