[Ffmpeg-devel] Memory leak in output_example ... ?

[Mat]

Hi all.
Again with  output_example.c ...
If I run  output_example  in valgrind or with mpatrol I got some memory 
advices.
I would like to use  output_example  as base for an application that 
produce many videos continusly but first I need to solve this problem.
I started to making the application and monitoring it with  ps  ( ps u 
-C myApp )  and I see an increment of the memory usage ( about 1% every 
4 hours )
It seems related to  av_new_stream  and  avcodec_open ...
Anyone can help me ?
Perhaps I could use another sample code... what can I use as base?

My test:
    valgrind --leak-check=yes --show-reachable=yes 
--log-file=valgrind.log ./output_example test.vob
Result:
