Hi !

Since Xora launched a video how to for c7x0 serie on the open zaurus webpage, i really really want to try to get a universal how to.

i tweaked a bit his script, and here is waht i now use on my 750 :

mencoder $1 -srate 24000 -ofps 15 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=150:vpass=1 -lameopts cbr:br=64:mode=3 -vf scale=320:-2:::,eq2=1.0:0.6:0.1:0.7 -oac mp3lame -o Z-$1;
mencoder $1 -srate 24000 -ofps 15 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=150:vpass=2 -lameopts cbr:br=64:mode=3 -vf scale=320:-2:::,eq2=1.0:0.6:0.1:0.7 -oac mp3lame -o Z-$1

use/edit/comment as much as possible for each Z model. I saved it as vid2zaurus and use it by "vid2zaurus file.avi". This produces a Z-file.avi.

Note that Z-file :
* automatically keeps aspect ratio
* needs around 100mo/hour
* enlight colors so that you can see them even without full lightscreen
* is a bit chunky as it is only 15 fps
* produces each one of the two passes at around 50 fps on my duron 1.3 ghz 512mo ram. (So a 2 hours film would be ready in about 2 hours.)

To play it, use Xora's script :

#! /bin/sh
fbset -n -xres 240 -yres 320;
echo 1 >/sys/class/graphics/fb0/driver/w100fb/fastpllclk;
mplayer -cache 16384 -vo w100 -ac mad -ao oss -framedrop -fs -really-quiet -vop rotate=1 $@;
fbset -n -xres 640 -yres 480

#! /bin/sh
fbset -n -xres 240 -yres 320;
mplayer -cache 16384 -ac mad -ao oss -framedrop -really-quiet -fs -vop rotate=1 $@;
fbset -n -xres 640 -yres 480

remove the two fbset lines (and i have a doubt about the w100 driver for GPE users...)

Now things i'd like to know :
- is there a way to keep the black frames really black ? the enlighting process makes the darks frames look ugly, but without it, movie are unwatchable unless you are in the dark... Anyone who knows anything in matrices is welcome.

- what is the maximum bitrate each Z models can play ? i need testers for this, or someone who knows haow to calculate this.

- is there a way to make a gui from this ? i don't know anything in coding, if someone wants to take that, that would be great ! Something with a bitrate calculator, and all. (wonder if it would be very usefull...)

- can someone make the same job for Windows users ? i know virtualdub has some sripting abilities in filtering, and that the filtering process can be saved in a file. Can someone post those files here ?

hi all !

snes9x doesn't work here on my c750 oz 3.5.3 opie. The sound works but the screen is blank. sdl is up to date (and instalation is checked). Any idea ?

Hi !

i've just flashe Open Zaurus 3.5.3 on my Zaurus sl-C750 with a 2.6.11 kernel. I can't access the network at all from the Zaurus...

The desktop pc is a mandrake 10.1 with a kernel, and i'm connected to it trough usb.

- Usb0 is up and configured on the zaurus side.
- usbnet is loaded on the mandrake side, but i can't get usb0 up on it.

I did everything that was told on the oz website, but it doesn't work.

the strange point is here (on the zaurus side) :

usb 2-2: new full speed USB device using address 25
usb 2-2: configuration #2 chosen from 2 choices

I don't understand the 2 choices part.

"usb0: register usbnet at usb-0000:00:10.3-1, Linux Device, 3a:6b:24:1f:af:0a" is what i should get with dmesg...
what is the file that rules this registration ?

thanks in advance for your precious help.

Some bugs have been found in Open Zaurus 3.5.3. We all know at least one.

Please use this thread in order to list them, so that the developpers' work become more efficient.

Please organize your posts, it will be easier to read. A static form could be usefull. I suggest this form

- Zaurus model
- kernel version
- opie or gpe
- last upgrade date
(bugtracker where bug is reported and bugnumber)

SOLUTION (if found) :


I hope it will be useful.
