Hi!
Anybody using vdr-1.5.10, dxr3 and subtitles?
I'm (trying to) use it, but all subtitles have the lines caused by "too many colors in a region". I can't find the dxr3-compatibility option that used to be there in the plugin. I have disabled antialiasing in vdr's OSD settings.
Anybody got dxr3 working with subtitles properly in this version? Perhaps there's a patch somewhere I haven't found? Or the setup option is hidden somewhere I couldn't find it? Or, maybe it hasn't been implemented yet in vdr-1.5.10 at all?
Just wondering,

VDR reduces the colors if the output device can't display all of them.
Maybe the dxr3 device doesn't correctly respond to the CanHandleAreas() call?
See cDvbSubtitleConverter::FinishPage(), the calls to sr->ReduceBpp() and sr->ShrinkBpp().

Yes, I think you are probably right. I looked at the code and modified it so that bpp ís always reduced to 2 (I think) - hack included. I'm not a programmer and know nothing about C++, really. But it works for me (kind of - see below). Of course, this is not a proper fix.
But, I think from previous the discussion here, that the color depth dxr3 can handle isn't that straightforward for. It can handle 8bpp but in a limited way; so just reducing bpp would not use the dxr3 hardware to the full potential. Some additional checking and processing is needed? Though I'm just an end user really, I don't know really, I'm kind of guessing =). Anyways, the subtitles look really good even with 2bpp, so in this case I think just reducing is sufficient.
There's still problem even after reducing the bpp; I think the OSD levels isn't properly implemented in the CVS (dxr3-0-2 branch). I'll post about this in the dxr3plugin-users list. (Symptoms: No other OSD is shown while subtitles are shown, previous subtitles aren't "cleared").

Oops,
wrong patch!
Right hacky thingy attached.
