New Revision: 15127
   Changeset: http://cvs.mythtv.org/trac/changeset/15127

Modified:

   trunk/mythtv/libs/libmythtv/osdtypeteletext.cpp

Log:

Fixes #4274. Don't draw a completely transparent Teletext line.


This checks a line before we try to render it to make sure that there is at least one opaque character on the line, if there isn't we skip it. This makes teletext encoded closed captions consume less CPU since only a few lines need to actually be rendered (as opposed to teletext menus which need to be rendered over the whole screen.)
