Linux and OSX systems support basename and dirname via <libgen.h>, I plan to
make the wrapper interface conform to the standard interface first.
If it is feasible, I will continue to modify it to call the system interface
if there is already a system call interface.

You can get more description about the system interface by below command:
 "man 3 basename"

Current default is 200kbps, which produces inconsistent
results (too high for low-res, too low for hi-res). Use
CRF instead, which will adapt. Affects VP9. Also have
VP8 use a default bitrate of 256kbps.
