Is it a slight memory leak in Crystal Driver

[valpa]

Hi

I use mplayer -slave -idle mode to playe movie all days long. When a
movie finished, it will automatically load another movie without
existing mplayer program.

I then monitor the memory usage in /proc/xxx/status : VmSize, it shows
the memory usage will slightly increase per minutes. after several
days. My 1G ram used up.

I don't know how to give further information. If need, pls tell me.

Thanks,
valpa

Can you send a kernel log for this scenario? Need to check if the sequence of closing and opening handles is clean.

Could be a memory leak elsewhere than in the driver.

Also do you see any allocation errors in kernel mode?

Because closing and opening handle will take about 2 seconds, I change
the code without closing/opening handle. For each movie, just close
and reopen the decode.

will it be a problem to keep handle opening, and close/open the
decoder consequently?

kernel log for keep open/close the handle. I believe there is no mem
leak if handle close/open for every movie.

When I bypass the open/close handle, the log is: (there have memory
leak)
