Ahhh... now I see... same logic...
If I modify  mpeg12.c:800  ,  av_mallocz  in  av_mallocz_static  another 
memory leak is gone!
And finally if I modify  utils.c: 767  ,  av_malloc  in  
av_mallocz_static  all memory leaks is gone!
Thank you!

av_malloc  vs  av_mallocz ... utils.c: 767 ...
is this good ?
