Title: Divx Encoding For Z
Post by: daemon1 on June 21, 2005, 03:14:23 am

hi everyone,

been trying for the last 2 days to find the best encoding and resolution for the zaurus to play divx's nicely...
(this has been done on a c3000)

firstly you need to use tetsu 18a kernel with bvdd iwxmmt and mplayer 1.1.5 from atty.jp

I've tried to sqeeze movies down the smallest possible size whilest having an acceptible quality. in my trials ive tried the following on the same divx.

Code: [Select]

mencoder -cache 4000 -vf scale,expand=0:-60 -zoom -xy 320 -ffourcc XVID -oac lavc -lavcopts acodec=mp2:abitrate=48 -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=448 -ofps 25 -sws 2 ./input.avi -o ./output.avi

Output.avi = 233507436bytes small widescreen
"mencoder -vf dsize=640:480,scale=320:240,expand=0:-60  -sws 2 -o Output2.avi -oac mp3lame -lameopts preset=96:mode=0:vol=10 -ovc lavc -lavcopts vcodec=mpeg4:vhq:v4mv:mbd=2:trell:cmp=3:subcmp=3:mbcmp=3:vbitrate=200:autoaspect
-ofps 23.976"

"mencoder -vf dsize=640:272,scale=320:136,expand=0:-104 -sws 2 -o Output1.avi -oac mp3lame -lameopts preset=96:mode=0:vol=10 -ovc lavc -lavcopts vcodec=mpeg4:vhq:v4mv:mbd=2:trell:cmp=3:subcmp=3:mbcmp=3:vbitrate=200:autoaspect
-ofps 23.976"

mencoder xxxxi -vf scale,expand=0:-60  -zoom -xy 320 -sws 2 -o Output3.avi -oac mp3lame -lameopts preset=96:mode=0:vol=10 -ovc lavc -lavcopts vcodec=mpeg4:vhq:v4mv:mbd=2:trell:cmp=3:subcmp=3:mbcmp=3:vbitrate=200:autoaspect

best one??

this will work???

along the way found a weird thing, the :autoaspect breaks bvdd and doesnt play any avi anymore... reboot is needed to fix the problem...

to play the movie you need to add "-vm -vo bvdd -fs output.avi" either manually in terminal or in kino2 or zplayer options.

anyway after painstakingly encoding all the options above... found the best one, which makes the movie full screen, sound in sync, good clear resolution and an acceptable size = 230MB down from 704MB... and the winner is...

Code: [Select]

mencoder xxxx -oac mp3lame -lameopts preset=96:mode=0:vol=10 -srate 24000 -vop scale=320:240 -o output17.avi -ovc lavc -lavcopts vcodec=mpeg4:vhq:v4mv:vbitrate=200 -ofps 20 -sws 2
try it with your movies and let us know how it goes....

Title: Divx Encoding For Z
Post by: speculatrix on June 21, 2005, 06:58:24 pm

I'm afraid I went the lame route and booted windows on my desktop PC, and used the windows media encoder with registry hacked to allow mp4 video/mp3 audio:

Am still playing with best settings, but it works for me.

Below are the sample of converted VGA movies.
Simply plays them on C3000 after used tetsu 18a kernel with bvdd iwxmmt ,mplayer 1.1.5 ,zplayer from atty.jp.
I can play them on C3000 smoothly,
I would like to know whether C1000/Cxxx can play it or not.
Please give some comments.THANKS.

I use Window Media Encoder,too.
I am using the same method from this tutorial.
http://www.double.co.nz/zaurus/ (http://www.double.co.nz/zaurus/)
But I changed the settings that shows below.
