Hi ML, Hi dxr3plugin lovers,
Attached to this posting is a patch which fixes the odd problem making
the osd
turn pink after returning from mplayer or after hardware-reset of the
dxr3-card.
I posted this fix in a german-vdr-forum a couple of months ago and it
works for other users there, too. I haven't found the time to post it
here (other users hadn't either:) )... so,
here it is.
Now what this patch does is it changes some behavior of cDxr3PaletteManager.
It seems, that after returning from pmExtern_THIS_SHOULD_BE_AVOIDED,
palette-data in cDxr3PaletteManager is somehow broken after
resuscitation (whatever happens there, the code is
a total mess).
I avoid this by *not* converting the whole data allover again in
cDxr3PaletteManager::GetPalette() through Tools::Rgb2YCrCb() and copy it
to m_pal (only when palette-data has changed, indicated by member
m_changed, should speed up the whole process a bit additionally).
This patch may be applied to current CVS (HEAD or MAIN, also vdr-dxr3-0-2).
Give it a shot !
Bye,
