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.
