I was looking at this to see if we could use the chromaosd stuff for
the PVR 350 which only supports Xv not XvMC. The main reason is that the osd
drawn by X is much nicer than the blended Xv one which flickers horribly.
The attached patch appears to work for me.
Is there any reason to not implement it for Xv as well, especially since
enabling it in the settings table tries to use it but it breaks horribly.Thanks John > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:mythtv-commits- > [EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] > Sent: 25 October 2005 00:07 > To: mythtv-commits@mythtv.org > Subject: [mythtv-commits] mythtv commit: r7569 by danielk > > Author: danielk > Date: 2005-10-24 23:06:36 +0000 (Mon, 24 Oct 2005) > New Revision: 7569 > Changeset: http://cvs.mythtv.org/trac/changeset/7569 > > Modified: > > trunk/mythtv/libs/libmythtv/NuppelVideoPlayer.cpp > trunk/mythtv/libs/libmythtv/osdsurface.cpp > trunk/mythtv/libs/libmythtv/osdsurface.h > trunk/mythtv/libs/libmythtv/videobuffers.cpp > trunk/mythtv/libs/libmythtv/videobuffers.h > trunk/mythtv/libs/libmythtv/videoout_xv.cpp > trunk/mythtv/libs/libmythtv/videoout_xv.h > trunk/mythtv/libs/libmythtv/videooutbase.cpp > trunk/mythtv/libs/libmythtv/videooutbase.h > > Log: > > References #512. > > This implements a basic chromakey OSD. > > For it to be enabled, you must have this in your > xorg.conf "Devices" section: > Option "XvmcUsesTextures" "false" # use 3d engine for overlays > And you have to insert a "UseChromaKeyOSD","1",hostname setting in > the settings table. > > This currently makes no claim to efficiency, this clears the a > buffer to the chromakey color w/borders, and then plops the OSD > on top of it; creating an RGB OSDSurface or creating a specialized, > chromakey painting, OSD blend function would probably be much > faster.
