Maybe, but not sure it is worth the effort. Many codec seems to do that.
The leaking one doesn't :)
It is not to hard call one function in implementation and it is easier
to read for others.
I'm trying to write some tests that allocs/deallocs codecs with "random"
options to find leaks/crashes and so far only few codecs leaked. Maybe
after this patch is created it will be safer to introduce that auto
You didn't comment patch itself.
