I tested it on mingw (For this i forced configure to set HAVE_SNPRINTF as false), and as is ffmpeg would not print anything. Changing that line to _vsnprintf fixed it.
snprintf.h does a "#define vsnprintf avpriv_vsnprintf", so i figured avpriv_vsnprintf() was basically calling itself.

If this behaves as expected when using MSVC then disregard what i said.
