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. + + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
