[MPlayer-dev-eng] [PATCH] OSD flickering with dfbmga

[mplayer at interlinx.bc.ca]

Here is a patch which corrects the OSD flickering issue that I
reported to mplayer-users.  Because the OSD is written to a DirectFB
"layer" (which is blended with the layer the video is in by DirectFB)
it does not need to be blended with every single frame displayed and
updates to the layer only need be done when the OSD actually changes.
This patch only "Flip"s the sub-picture layer when there was actually
an OSD change.

Please apply ASAP.

Thanx,
b.
