I did some testing on that with GTA01. > Please correct me if I misunderstood. Even with GTA01 it was possible - though the tests I made there are not valid for GTA02 (don't have one yet). What I found out with mplayer is: 1) H.264 will take to much time to decompress (even at low bitrates) 2) SDL will be the fastest way to output without HW acceleration 3) using H.263 (as Youtube does) I could get the best compression/bitrate/speed ratio 4) using 320x240 and scale to 640x480 (480x640) is doable Some of those findings are documented at the buttom of http://wiki.openmoko.org/index.php?title=Video_Player > If I interpreted Carsten right 640x480 video will > display at 5-10 fps at best, right? Actually with GTA01 I've had 13 fps in fullscreen mode (320x240 -> 480x640) which looked really okay and was viewable. A 640x480 H.263 though with reasonable bitrate took to much cpu-power to decode. Anyway, with GTA02 you should take a try - it seems doable in SW even without 2D acceleration, as it just has more cpu power. - try to start with: mencoder -quiet -ofps 13 -vf scale -zoom -xy 352 -af channels=1:0:0:1:0 \ -oac lavc -ovc lavc -lavcopts \ acodec=mp3:vcodec=h263p:autoaspect=1:vbitrate=200:abitrate=32 \ -o <outfile> <infile> mplayer -autosync 30 -vf scale -zoom -xy 640 -vf rotate=1 -sws 0 -nodouble \ -vo sdl -fs -framedrop <tagetfile> Greetings from Berlin Kristian -- /* Web: http://www.mput.de | Tel: +49 (0)170/6692447 * * Blog: http://mput.de/blog | ICQ: 93248497 * * GPG-ID: 4BBB6525 (..2009) | Jabber: [EMAIL PROTECTED] * * Twitter: kristian_m | MSN: [EMAIL PROTECTED] */ _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
