[Ffmpeg-devel] Memory leaks with some codecs... (again)

[Mat]

Hi all...
Some months ago I posted a message (and a small patch) for some memory 
leaks...
I did the same test again on the current CVS version (debugger: 
valgrind) and I see that they are there again.
I think it could be useful to correct them... :)
I don't know If the changes I proposed the last time are corrects ( 
av_mallocz -> av_mallocz_static ).
If someone can tell me something it will be very appreciated...
Greetings,
-Mat-
