"Subtitle filter" plugins

Hi all.

What are the best possible approaches to be able to receive subtitle text input in plain text, without rewriting Freetype renderer's code - exactly, to avoid any modifications in main source tree?

// currently I look at Marquee's source code, but feel there's something incomplete with its SUBCAT_VIDEO_SUBPIC implementation.

sub filter plugins should be able to access the text before rendering.

Nope..

subpic filters (as in SUBCAT_VIDEO_SUBPIC, "sub filter", pf_sub_filter) are seemingly receiving empty p_subpic->p_region value in pf_sub_filter call, so p_subpic->p_region->psz_text route is unavailable.

Then there are no existing ways.
