I have a simple suggestion that eluded me on my previous email
and could have prevented the rant I wrote. :(
Let's remove the OPTIONS ASS (for libass) entry AND let's simply
depend on multimedia/libass.
It is simple and fulfills every criteria:
1) port is going to build
2) no option will be ignored
3) POLA is upheld since the port was built with ASS subtitle
support before and it will continue to be. The only difference
is that it will always use an external library instead of the
internal one.
Let me know what you think. A multimedia/mencoder patch is attached
as a suggestion. Is this compromise acceptable?
Best regards,
