luvcview -f yuv

this command helps me to view my cam

but other utilities like gstremer camorama and cheese are failing

business_kid

you have 3 posts. Let me try

lucview. That's mildly interesting and verifies a few things.
gspca module. How does lucview do it? Otherwise I would expect some camera module.

Libraries: Probably no libs in /usr/lib64 is a problem, and you will know if everything else has their libs there. I should explain
/begin history lesson
On the making of 64-bit distros, most people left 32 bit libs in /usr/lib for compatability with existing software, and put 64-bit ones in/usr/lib64#
Somebody, (Debian, afaik) felt that 'native' libs should go in /usr/lib (64-bit in the case of a 64 bit system) and invented /usr/lib32 for 32 bit libs. A 64 bit system usually needs some of both.
/end history lesson

Try
file /usr/lib/vl412.*
file /usr/lib32/vl412.*

Watch for 32 bit or 64 bit. Then try 'ls /usr/lib64' & 'ls /usr/lib32'

ONE of those will have very few libs, and they are misplaced. If you have Debian, it will be /usr/lib64. Otherwise, /usr/lib32 are the orphans. They will have to go to/usr/lib, and the equivelants in /usr/lib to /usr/lib64. Then run ldconfig.

lucview it tells that driver is a uvcvideo


#modprobe -l | grep ov
kernel/drivers/media/video/ov7670.ko
kernel/drivers/media/video/ov772x.ko
kernel/drivers/media/video/ovcamchip/ovcamchip.ko
kernel/drivers/media/video/gspca/gspca_ov519.ko

kernel/drivers/media/dvb/dvb-usb/dvb-usb-nova-t-usb2.ko
kernel/ubuntu/lenovo-sl-laptop/lenovo-sl-laptop.ko


and i confirmed the directory structure is ok

will compiling my own kernel help?

what is the procedure to show my kernel image in grub-2?

business_kid

It wasn't your directory structure I was worried about.
Your library search path would not have /usr/lib32 and /usr/lib64. That's the issue
One of them is wrong. either that or add them both to /etc/ld.so,conf & run ldconfig

ankscorek

cat /etc/ld.so.conf.d/libc.conf
# libc default configuration
/usr/local/lib
/usr/lib32
/usr/lib64





the problem still remains the same
no change in error also

sudo LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so camorama -d /dev/video0
ERROR: ld.so: object '/usr/lib32/libv4l/v4l1compat.so' from LD_PRELOAD cannot be preloaded: ignored.

business_kid

Well it has told you what's wrong, so we don't have to.

Check /usr/lib32/libv4l/v4l1compat.so. run

ls /usr/lib32/libv4l/ (should show files)
ldconfig ( should show nothing but is a good idea)
ldd /usr/lib32/libv4l/v4l1compat.so and look for things not found

ankscorek

is the one in red the errorenous part? do i do a ln -s?
