I have a wmv file (about 130MB) in the sd card, i reset and reboot the
device , the mediaserver process will occupy 90%+ cpu and keep that status
until the battery dry out.
I used gdb to debug the mediaserver process, but it seems I can't get the
all threads info, normally I just can see one thread. At one time, I get
all the thread info occasionally, and I will attach them below.
It's odd that I wrote some debug log info in the code but the log can't
output, it seems the stack below may not belong my problematic wmv file but
some files in the phone.
I am sorry I can't attach that wmv file for it's too large comparing to the
permission of gmail.
