Replying to [comment:3 Cigaes]:

{{{avcodec_close}}}?
I did not open the codec context so there's no reason to close it, I
presume. By the way things get unchanged even if you close the context or
you open and close it. the leak is in between the two calls
{{{
DestCodecCtx = avcodec_alloc_context3(codec);
avcodec_copy_context(DestCodecCtx,SourceCodecCtx);
}}}
and closing and freeing it will not avoid it, because in the call some
memory is allocated for
{{{DestCodecCtx->priv_data}}} and in the second call the pointer is set to
NULL without freeing the memory previously allocated.
