[mythtv] XvMc-OpenGL and OpenGL-OSD

[Daniel and Mary-Beth Sherwood]

Steve

The steps I have taken to get XvMC-OpenGL renderer and OpenGL OSD working (to give a Colour OSD with XvMC decoding) are as follows...

1) rebuild MythTV 0.21 (trunk will probably be the same) with --disable-xvmcw --disable-xvmc-vld --disable-xvmc-pro --enable-xvmc-opengl

2) set the Playback profile to xvmc-opengl renderer and opengl OSD.

3) Try it.

If you get something displayed but it appears to be corrupt (I have seen various comments describing vertical bars, horizontal bars or just a subsection of the image being displayed) then apply the attached patch to libs/libmythtv/util-opengl.cpp and try again.

Good luck

Daniel
