This option (as well as others like skip_alpha, or refcounted_frames
which is also missing in this file) are boolean, not int.
In practice it makes no difference i guess, since the actual
AVCodecContext fields are all int anyway, but maybe it could be
reflected here. I'm not sure if the difference between AV_OPT_TYPE_BOOL
and AV_OPT_TYPE_INT has any implications for API users, though.
