Try loading module with vflip=1 parameter lile following:
insmod microdia.ko vflip=1
You can also change flip values via sysfs:
echo 1 >/sys/class/video4linux/video0/vflip

[Vinicio Nocciolini]

root@localhost ~]# cd /home/vinicio/microdia/
root@localhost microdia]# modprobe videodev
root@localhost microdia]# modprobe compat-ioctl32
root@localhost microdia]# insmod sn9c20x.ko vflip=1
root@localhost microdia]# LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so

mplayer tv://-tv
driver=v4l2:width=640:height=480:fps=25:device=/dev/video0 -vo x11

Resolved!
Adding nvflip=1 Now it s working in the right mode :)
Thanks a lot!!!

Hi again
Now I would like Installing the Microdia Driver

I don't want to do insmod sn9c20x.ko everytime I reboot my computer.

the question is:
Where can I specify nvflip=1 as permant?
I have tried the follow commands but they don't know about nvflip=1

|

|# strip -g sn9c20x.ko
# mkdir -p /lib/modules/`uname -r`/kernel/drivers/media/video/usbvideo/
# cp sn9c20x.ko /lib/modules/`uname -r`/kernel/drivers/media/video/usbvideo/
# depmod -a

That depends abit on what distro you have on ubuntu and probably
generic debians there is a file located at

/etc/modprobe.d/options

which you need to add a line like

option sn9c20x vflip=1

There should be a similar file for other distros which let you specify
options to pass to modprobe for various modules

[Vinicio Nocciolini]

Now Its all OK :) :) :)

I tell u what I did on my fedora 10
in folder /etc/modprobe.d I have create a new file called sn9c20x
After I have edit it as:

# less sn9c20x
options sn9c20x vflip=1

BTW
There are F10 specs for an akmod package available here:
http://repo.or.cz/w/pkgmicrodia.git

The advantage:
akmod rebuilds the module automagically everytime you update your kernel.
(akmod is available at rpmfusion)
