In an effort to create something to solve such issues with
xineliboutput plugin I came up with an idea of this HUD type OSD.
Basically it means that OSD is rendered to a separate transparent
surface on top of video and then these are blended together by the
display hardware. This way the size of the OSD is bound to the size of
the used window rather than the size of the video stream. In other
words no OSD scaling will be necessary even though the video size
The HUD implementation has been integrated into the CVS of
xineliboutput plugin. To operate it requires support for xorg render
extension and presence of composite display manager such as xcompmgr.
It also requires powerful display adapter and drivers with support for
these modern extensions. Maybe you can try it to see if it produces
results that you are hoping for?
