Talk:Ov51xJpegHackedInstall
From Ov51x JPEG hacked Wiki
This installation doesn't seem to work for fedora core 5 test 3. Everything up until modprobe works perfectly - but then things starts to act weird. Here is a peek at my shell:
#> modprobe ov51x FATAL: Module ov51x not found. #> #>insmod ov51x.ko insmod: error inserting 'ov51x.ko': -1 Unknown symbol in module
I should mention that the update-module method seems to be missing from fedora... Also I'm running kernel "2.6.16-1.2080_FC5smp"
Please try to provide a dmesg output. Also, using insmod you should first do a modprobe videodev as stated in the page.. Then if it still doesn't work, post your dmesg output here..
