+This file adds an optimized vo output to mplayer for the OMAP platform. This is a first pass and an attempt to help to improve
+media playing on the OMAP platform. The usual disclaimer comes here: this code is provided without any warranty.
+Many bugs and issues still exist. Feed-back is welcome.
+
+This output uses the yuv420_to_yuv422 conversion from Mans Rullgard, and is heavily inspired from the work of Siarhei Siamashka.
+I would like to thank those two persons here, without them this code would certainly not exist.
+
+Two options of the output are available:
+fb_overlay_only (disabled by default): only the overlay is drawn. X11 stuff is ignored.
+dbl_buffer (disabled by default): add double buffering. Some tearsync flags are probably missing in the code.
+
+Syntax is the following:
+mplayer -ao alsa -vo omapfb /test.avi
+mplayer -nosound -vo omapfb:fb_overlay_only:dbl_buffer /test.avi
+
+You need to have two planes on your system. On beagleboard, it means something like: video=omapfb:vram:2M,vram:4M
+
+Known issues:
+1) A green line or some vertical lines (if mplayer decides to draw bands instead of frame) may appear.
+It's an interpolation bug in the color conversion that needs to be fixed
+
+2) The color conversion accepts only 16-pixel multiple for width and height.
+
+3) The scaling down is disabled as the scaling down kernel patch for the OMAP3 platform doesn't seem to work yet.
