Re: mplayer OSD rendering using 100% CPU with VDPAU
FYI, I've filed internal problem report #793119 for this.
Can you please provide the exact MPlayer command-line you're using.
Just to be clear, when you say OSD you aren't referring to subtitle data within the media file, but OSD such as what MPlayer shows when volume/brightness/... is adjusted. If so, can you also state exactly how you're triggering that.
Did you build MPlayer yourself? If not, which package did you install? If so, can you state the exact SVN revision you built, and the configure command-line you used.
