[Bug 41779] Re: webcam error - ov511.c: No decompressor available

[alexroat]

Hello !
Finally, I've got a definitive solution for using my Philips ToUcam 720k on Gutsy Gibbon.
This is the "recipe" :

install this package:
sudo apt-get install ov51x-jpeg-source

install also the headers of linux kernel:
sudo apt-get install linux-headers-2.6.22-14-generic 

move to jpeg decomp module source directory
cd /usr/src/modules/ov51x-jpeg

compile the jpeg decompression module
sudo make

copy the module in module tree
sudo cp ov51x-jpeg.ko /lib/modules/2.6.22-14-generic/ubuntu/media/ov511/

update the module dependency database
sudo depmod -a

now, unload the ov511 module
sudo rmmod ov511

load directly the decomp module, it will load the devide driver module automatically
sudo modprobe ov51x-jpeg

now, test the module with vlc
vlc -> click on play key -> choose video4linux -> insert the correct device file (/dev/video0 if you dont have any other acquisition card, otherwise /dev/video1 and so on ) -> ENJOY your bad face :)


PS: change the name of kernel headers and modules directory according with the one that you are using, you can discover this magic name/number with the command "uname -a".
At this moment, i ear an high frequency noise which is quite annoying, but video works perfectly !!! It should work for every ov51x based wabcam.
Moreover, In the next days I will try to fix an automatic loading of the decomp module with udev. In the meantime enjoy your old camera working.
