[FFmpeg-user] Help free() invalid pointer

[NDJORE BORIS]

Hello all,
I need help please.
I use ffmpeg in my cpp program.
In the  main of my main.cpp file I initialize two times codeccontext and
filtercontext.
Because at one hand, I extract motion vecteur and do somes actions
(editing) on them (mvs).
And at the second time, I put edited motion vectors in the output file
during reeconding.
The functions that do the actions (edit) on motions vecteurs are in an
other .cpp file (editmv.cpp).The header file of  editmv.cpp is included in
an other header file witch is included in my main.cpp.
 but when I run the executable. At the end of the first action witch is the
extraction and editing of mvs in the other cpp file, when my program comes
back to the main at second time to reencode the video, I get this error :
free(): invalid pointer: 0x00007fffffffe001.

Can someone help me, please?

This is the valgring command output :
