Argh. Okay, I'm stuck again. I need help getting SPU's to display.
1) I hooked all the spu and sub demuxing stuff up to work with the
STREAMTYPE_DVDNAV.
2) There are SPUs in this DVD. ("Found subtitle: 0" and "...: 1")
3) They show up in the stream at about the time I'd expect the
highlighting to happen (using -sid 1, or -sid 0).
4) They are "Menu Id"(0) types not "Start Display"(1). However, according
to the SPU specs I've read, type 0 is actually called "Forced Start
Display", so I changed spudec to treat it like a "Start Display".
5) I've verified that there is SPU image data (next_line gets called a
lot).
6) I've verified that draw_alpha is getting called from
spudec_draw_scaled, which is getting called from the osd subsystem.
Problem is: I don't see anything new on the screen.
I'm suspecting palettes maybe?
Is there a way to examine the SPU image? I'd like to know what I should
be expecting to appear.
