I think the design not so much, the implementation in MPlayer is more of
a problem though, since the "decoding" is done in the demuxers (support
for ogg and mkv is added), instead of in mp_common.h.
Probably because demux_ogg still uses the old and broken way of setting
subtitles (modifying vo_sub directly instead of creating a proper
subtitle stream).
