◆ GetRenderOptions()

void MythVideoOutputOpenGL::GetRenderOptions ( RenderOptions Options)
static

Generate the list of available OpenGL profiles.

Note
This could be improved by eliminating unsupported profiles at run time - but it is currently called statically and hence options would be fixed and unable to reflect changes in UI render device.
