Is there some specific reason, why there is no macro
used for this, in order to avoid similar mistakes?

#define MKVERSION(a,b,c) ((a)<<16+(b)<<8+(c))
...
#if LIBAVCODEC_VERSION_INT >= MKVERSION(52,0,0)

or similar?

Of course it's a pretty simple element, but the same
things are repeated through the code, a macro might
simplify potential future changes.
