Did anyone use a usb video camera ?

I need to capture images and store them at hdd

I tried install Palantir, but there are errors like
Code:
efika:/Palantir/server_# make
gcc -Wall -D_REENTRANT -O2 -g -c -o jpeg.o jpeg.c
jpeg.c:15:21: error: jpeglib.h: No such file or directory
When I try use ready program I see
Code:
efika:/Palantir/serverPPC# ./palantir
./palantir: /lib/tls/libc.so.6: version `GLIBC_2.4' not found (required by ./palantir)
I installed available one
Code:
efika:/Palantir/serverPPC# aptitude search glibc
v glibc-2.3.6-2 -
v glibc-2.3.6.ds1-1 -
p glibc-doc - GNU C Library: Documentation
v glibc-pic -
i libg++2.8.1.3-glibc2.2 - The GNU C++ extension library - runtime ve
i A libstdc++2.10-glibc2.2 - The GNU stdc++ library
Have anyone idea what I did wrong?

The premade one is obviously for a future version of the distro you're using (I will assume Debian here?) so you will have to compile it yourself as above.

If you're missing a header, you basically just need to install the development package for that library. They're usually named in a really hinky way though.. you may just have to apt-cache search libjpeg* and have a look for example.

everything look ok
now I try to connect from another machine I paste efika IP address in web browser forexample

http://192.168.0.1:3000

and I see a black preview

at efika I see something like that
Code:

Mar 25 11:01:46 [main] 1 client(s) connected

Mar 25 11:01:46 [video] CMCAPTURE - mmap failed, should revert to
read(): Device or resource busy
Mar 25 11:01:46 [video] CSYNC: Device or resource busy
has someone meet with a similar problem?

You may need to run the webserver at a higher permissions level (or reduce the permission requirements on the video device). Web server users like "www" usually have absolutely no access to this level of hardware use.

"Device or resource busy" could mean anything, some error code like -ENODEV or -EBUYS which is used for a hell of a lot of things.

It would help if I could quickly look at the source that is producing the error... is that text output coming from Ruby or from a system library?

I made mestake, I thought that /dev/video0 is my camera, I compared Windows drivers, and I found that it recognize my camera as UVC camera, so I installed Debian package linux-uvc-source, then I load modules
Code:
efika:/home/# lsmod
Module Size Used by
uvcvideo 63144 0
radeon 139688 0
drm 91384 1 radeon
agpgart 37500 1 drm
evdev 12576 2

dmesg:
Code:
usb 1-2: new full speed USB device using ppc-of-ohci and address 6
usb 1-2: configuration #1 chosen from 1 choice
uvcvideo: Found UVC 1.00 device Sirius USB2.0 Camera (0ac8:3343)
uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling
workaround.
input: Sirius USB2.0 Camera as /class/input/input3
after thaht I found /dev/video1, so I changed default config and set Video as /dev/video1, but now it is some kind problem with "video channel"
Code:
efika:/home/# palantir
Mar 26 01:55:41 [main] -- palantir 2.7 starting --

A quick search turned this up (Dutch) http://gathering.tweakers.net/forum/lis ... es/1303847 - no solution.

The second result on Google is this thread! :(

Well, I am sorry I cannot help you, I don't know enough about what you are trying to do nor can I really test it out to see what the problem is. It's really not an Efika problem but a general Linux problem (the thread above is certainly just someone with a PC).

You might have much better luck posting to a forum specifically for Palantir or any other related software you're using.
