[GnomeMeeting-list] YUV420P Mandrake 9.1 fix

[Adam Flinton <adam softfab com>]

Dear All,

Had the problem of upgrading mandrake from 9 to 9.1 & getting the "Your 
driver doesn't support the YUV420P format" error message.

Just download the pwcx-8.2.2.tar.gz & use that instead of the file 
reff'ed below (& the .o is the /gcc-3.2/pwcx-2.4.20.o ).

Other than that following the instructions below worked.

"I have a fix for this but it will probably require a package in plf as

it requires a non gpl'd binary only module. 

Apparently sometime between 9.0 and 9.1 the developer of the pwc driver
has changed the way the pwc module works with the Logitech (philips
chipset) Quickcam Pro 3000. Below are the steps I took to get it to work
in Mandrake 9.1:

1.)Download the pwcx module from
http://www.smcc.demon.nl/webcam/pwcx-8.2-gcc32.tar.gz

[root foo root]# wget
http://www.smcc.demon.nl/webcam/pwcx-8.2-gcc32.tar.gz

2.) Untar the binary module and copy it to the kernel modules directory.

[root foo root]# tar -xzvf pwcx-8.2-gcc32.tar.gz
[root foo root]# cp pwcx-8.2-gcc32/pwcx-gcc32.o
/lib/modules/2.4.21-0.13mdk/kernel/drivers/usb/pwcx-gcc32.o
       
3.)Add the following line to the end of your /etc/modules.conf

post-install pwc /sbin/insmod --force
/lib/modules/2.4.21-0.13mdk/kernel/drivers/usb/pwcx-gcc32.o >/dev/null
2>&1  || :

[root foo root]# echo "post-install pwc /sbin/insmod --force
/lib/modules/2.4.21-0.13mdk/kernel/drivers/usb/pwcx-gcc32.o >/dev/null
2>&1  || :" >> /etc/modules.conf


If you still have problems with gnomemeeting complaining when you open
the video device, you may need to set the color palette to rgb24 using
gconf-editor (reminds me of regedit *shudder*), drill down to apps,
gnomemeeting, devices. right click the key for "color_format" and choose
edit. Change it from yuv420p to rgb24.

If anyone (plf?) is interested in an rpm to handle all this I could
probably throw one together. 

Also if anyone knows how to get the integrated usb audio to work, or has
had luck using gnomemeeting with i810 audio, please contact me :)
