[vlc-devel] Sending synced text to the Qt4 interface

I don't understand what I'm doing. I haven't been hacking on VLC for long
at all, and I'm just grepping the code to see how stuff is done. The point of
this mail was to ask for feedback on just this. Note that feeding such a meta
from *all* SPUs is probably undesirable as well, hence the (perceived)
need to have a separate path for synced-text-to-draw-outside-video.
Could be a flag in the SPU data I suppose.

Didn't realize it was racy :/ Still, I was not aware that the vout was created
by my decoder. I certainly don't recall doing this code (especially the one
that opens a visualization window where lyrics get displayed).

Yes, I understand that, it was the point of me asking as it was the only way
I could find so far.

Thanks
