Some time ago a lot of people where complaining about FreeBSD not having the possibility to use a webcam. Okay, we had a gspca driver and some other drivers but only for v4l1 and most of them don't work anymore. Now we have webcamd and v4l2 and we (The FreeBSD people) can take advantage of that. Webcamd have a lot of drivers and also the important UVC driver. There are a lot of programs that are working with a webcam on linux and now these programs can work on FreeBSD. I have succesfully compiled and run the following programs on FreeBSD:

wxcam
guvcview
effectv
luvcview
uvcview
mplayer
mencoder
mjpg_streamer
uvc_streamer
camorama
camserv
motion
xawtv
zoneminder

I have screenshots of this programs running on FreeBSD 8.0 release. For more information, go to http://www.rockafunk.org/

Making ports of all of this programs can easy be done. I already have the patches. Any help is welcome.

Can you be more specific what is not working? Can you post some error messages. How did you install webcamd? There is a port of webcamd and you also need to install v4l_compat and libv4l. Do /dev/video0 exist?

mplayer and vlc work here. Skype and flash are still non-functioning (just gives green static). At least when I last tried about 2 weeks ago.

I have tried skype but no luck yet. For the video in skype to work, some patching need to be done in the kernel source. Skype on FreeBSD work under linux emulation and I think the patches only work only the pwc driver. The patches can be found at http://opal.com/freebsd/sys/compat/linux/.

Me too. Same problem with Zeiz. If i remember right it was refused to see camera on usb port or something like that.

Do /dev/video0 exists? How do you start webcamd? First you need to load cuse4bsd by doing kldload cuse4bsd Then do a dmesg in a terminal to find out the ugen number. My logitec camera gives "ugen4.3".

Load webcamd like this:
# As root or use sudo

webcamd -d ugen4.3 -i 0 -v 0

Also change the permissions of your video device.
# As root or use sudo

chmod 666 /dev/video0

Test with pwcview:

pwcview

I see that some people have problems installing webcamd. I like to help so I have written here how I have done it.

Get the latest port tarballs for v4l_compat, libv4l, pwcview and webcamd.
Also get the cuse4bsd source.
Just follow the instructions to do that.

Actually tried Skype :)
Anyway:

Hi zeiz, if your webcam supports the pwc driver you should only load that driver. If you put webcamd_enable="YES" in your rc.conf the webcamd driver will load on boot. And when you then do webcamd -d ugen2.2 -i 0 -v 0 you load the driver for the second time. Do not load the pwc driver and webcamd together.

zeiz

June 22nd, 2010, 16:19

Understandable. I just shown that webcamd is loaded.
However Do not load the pwc driver and webcamd together
Did you mean that webcamd will be loaded by pwc driver and thus no need in webcamd_enable="YES" in /etc/rc.conf?

adamk

June 22nd, 2010, 16:23

pwc is a driver for specific webcams.. webcamd + cuse4bsd should be used for webcams *not* supported by pwc.

Thanks but how could you comment this:

Test with pwcview:

pwcview
? cuse4bsd loaded, webcam loaded and then pwcview started. But you said that pwc is only for some webcams. Did you mean that for other webcams cuse4bsd+webcamd must be loaded to make pwcview working? And for those supported by pwc no need in both cuse4bsd and webcamd?
Sorry if I'm really dumb today :)

adamk

June 22nd, 2010, 16:54

There is the pwc driver (for specific webcams) and then there is the pwcview program, which is not specific to the pwc driver.

Adam

You are right. The program pwcview is just a program to view /dev/video0. The driver does not matter for pwcview. The pwc driver however is just for webcams supporting this driver. If you dont have such a webcam you dont have to load the pwc driver. So you are right!

zeiz

June 22nd, 2010, 18:01

So, assuming that pwcview works for both following cases, should I use webcamd + pwc if my webcam supported and webcamd + cuse4bsd othewise?

adamk

June 22nd, 2010, 18:16

Wow, you really are having a hard time with this:

Do not load the pwc driver and webcamd together

If your card is supported by the pwc driver, use it (do not use webcamd). If it's not supported by the pwc driver use cuse4bsd+webcamd.

zeiz

Got it working. Thanks, Chuchubi!
A couple of problems are here.
First video0 looks always being created under root credentials and editing of /etc/defaults/devfs.rules or /etc/devfs.rules or /etc/devfs.conf doesn't work here. Only chmod works for given session.

Second: during boot webcam first fails to start:
Starting webcamd
/libexec/libexc/ld-elf.so.1: Shared object libcuse4bsd.so.1 not found required by "webcamd"
/usr/local/etc/rc.d/webcamd: WARNING: failed to start webcamd
ELF ldconfig path: ..... /usr/local/lib ....
However
find / -name libcuse4bsd.so.1
/usr/local/lib/libcuse4bsd.so.1

Nevertheless webcamd starts later. I am on 9-current, it could be the -current problem.

Skype (tarball: skype_static-2.0.0.72-oss.tar.bz2) doesn't work yet: both video and audio.
On Linux same webcam works fine.

I would like to create the ports but I have to do a lot of reading and that may take some time. My experience with writing a port from scratch is very little at the moment. I have edited and upgraded some existing ports that were left alone by the maintainers. That is why any help is welcome. If you want to help I will send you the patches. Just let me know.

I am using FreeBSD version 8.1 (AMD64)

I installed V4l_compat, libv4l and webcamd.

I have checked to make sure that those software applications were installed correctly.

I have loaded webcamd_enable in /etc/rc.conf

I have also loaded the cuse4bsd in /boot/loader.conf

I have tried 3 different web cams and none of them are capable of rending streaming content.

I have looked at /var/log/messages and see no record of my device pluging in my web cam either. It does indicate or show a USB memory stick

I installed webcamd, loaded cuse4bsd module. My webcam is ugen7.2. However when I run webcamd -d ugen7.2 -i 0 -v 0 it displays

Attached ugen7.2[0] to cuse unit 0

and stops at it. The video0 device in /dev is created, but after waiting for an hour for webcamd to finish, I just stopped it with CTRL+C. Is there something wrong, or my camera is unsupported? I have Logitech C310, it's UVC-enabled, works on Debian stable OOTB.

Hello everyone.
I am trying to get a Logitech C160 webcam working on webcamd, to use it with motion software, but I smell unsupported hardware.

I have also the hunch that webcamd won't work on usb 2.0 ports ( I have no 1.1 ports on the box... dang ).

Said webcam is UVC-supported as in this page of the Logitech support forums ( http://logitech-en-amr.custhelp.com/app/answers/detail/a_id/6471 ) so I guess it should be supported by webcamd.
After I did everything that has been suggested in this thread, I still can't get it working.

anyway, the box is headless, so pwcview -h:
pwcview -h
yields
Failed to set palette to YUV420P: Invalid argument
so I tried with a lower res:
pwcview -s sqcif -h
but:
Failed to set palette to YUV420P: Invalid argument

usbconfig dump_device_desc dump_curr_config_desc
ugen2.2: <product 0x0824 vendor 0x046d> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON

bLength = 0x0012
bDescriptorType = 0x0001
bcdUSB = 0x0200
bDeviceClass = 0x00ef
bDeviceSubClass = 0x0002
bDeviceProtocol = 0x0001
bMaxPacketSize0 = 0x0040
idVendor = 0x046d
idProduct = 0x0824
bcdDevice = 0x0010
iManufacturer = 0x0000 <no string>
iProduct = 0x0000 <no string>
iSerialNumber = 0x0002 <340253A0>
bNumConfigurations = 0x0001

So it's definitely a video device.
I could not find a list of supported hardware with webcamd. Anyway motion says:

motion: [1] v4l_start: set input [8]
motion: [1] Retrying until successful connection with camera

webcamd -d ugen2.2 -i 0 -v 0 -B

ls /var/db/pkg | grep v4l

Any ideas? I guess my cam is not supported.

Thanks in advance to everyone.

March 23rd, 2011, 21:16

Unfortunately, I can't offer much in the way of advice. I do have a uvc webcam. webcamd does allow me to use some applications (mplayer, vlc, emesene) but, even so, motion errors out for me :-)

March 23rd, 2011, 22:46

I'll try to build motion as described in their wiki ( http://www.lavrsen.dk/foswiki/bin/view/Motion/FreeBSD ) with pwc support, crossing my fingers. Have to clean up after all the mess I made with webcamd tho :)
Thanks anyway.

Fiuz

March 23rd, 2011, 23:45

Update: I managed to re-install and re-compile motion with pwc support, re-compile pwc to the latest version, but I still can't figure why I have no /dev/video0. Driver is loaded correctly, and when I plug/unplug the webcam, dmesg reports:

ugen2.2: <vendor 0x046d> at usbus2 (disconnected)
ugen2.2: <vendor 0x046d> at usbus2

The system sees the hardware. At least it's something :) I want to try to create /dev/video0 manually since motion's log says that it can't access the device file.

mknod /dev/video0 c 81 0 root:wheel
returns
mknod: /dev/video0: No such file or directory
The man page says that mknod is deprecated since 6.0, what should I use to create manually the device? Devfs?

March 24th, 2011, 00:40

According to your first post, you do have a /dev/video0. It's created when webcamd attaches to the device.

March 24th, 2011, 09:10

Thanks for your reply, adamk.

I maybe am not clear with my post above, but since I have uninstalled webcamd in order to try with pwc/motion-with-pwc support, my /dev/video0 has disappeared. I need to recreate it.

My camera works fine in pwcview, but Cheese reports no device found. Its docs suggest testing the webcam in gstreamer-properties, but it also works fine there as the default v4l2 device.

Skype and Flash can't see a camera device either, but I'm not sure that works for anybody.

(Also has details how to get webcams working that don't support YUV video like the one I tested here.)

A few clarifications:

- The skype version tested was the one from the net/skype port, newer ones still need other patches: http://markmail.org/message/yilswgpnur4zawne

- To install Linux rpms (libv4l) see "Installing a Random Linux RPM Based Application" in the handbook: http://www.freebsd.org/doc/handbook/linuxemu-lbc-install.html

- You may need to restart skype after enabling video support.

- You may need to adjust device permissions in /etc/devfs.rules for /dev/video*.

I tried the flash site again, and this time it worked. skype (from net/skype) still crashes, though. I am setting XLIB_SKIP_ARGB_VISUALS=1 as per your directions.

Sounds like your camera (like mine which is also a gspca) doesn't support YUV video ootb, did you LD_PRELOAD the v4l2convert.so as mentioned in the thread I linked? Example: (bourne shell)
LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so /usr/local/share/skype/skype --resources=/usr/local/share/skype

And btw bsam@ now posted a port for the Linux libv4l that I just tested and I guess he will commit soon: http://lists.freebsd.org/pipermail/freebsd-multimedia/2011-April/011912.html

Maybe you use a different FreeBSD version/date of checkout on that box? Anyway, copyout_map() etc are only used by the DVB part of the patches which I now separated out into a port and fixed this issue in (separated because of LGPL in Linux DVB header files that I used parts of and got no reply about when emailing the author of those parts); I posted about the new patches here: http://lists.freebsd.org/pipermail/freebsd-multimedia/2011-April/011992.html

Link to the mailing list post again: http://lists.freebsd.org/pipermail/freebsd-multimedia/2011-April/011992.html

Turns out Alexander committed the patches to -current now (r221426), so since you run that you just need to update your /usr/src.

Is there a way only to rebuild the linux.ko without having to recompile the kernel?
Well there may be other unrelated changes that may require a kernel rebuild anyway, but in general you should be able to just cd to /usr/src/sys/modules/linux and run:
make DEBUG_FLAGS=-g install
(The same goes for /usr/src/sys/modules/sound/sound after applying the one-line sound.ko patch which has been committed as r221388.)

I now turned my Linuxolator V4L2 patches into a port: multimedia/linux_v4l2wrapper-kmod

So now people not running -current no longer have to find the right patch to apply to their 8-stable or release and rebuild their linux.ko, just install this port and do:kldload linux_v4l2wrapper
Thanx to Andrey V. Elsukov for turning my patches into a separate kld like I already did with the Linuxolator DVB patches: multimedia/linux_dvbwrapper-kmod

Thanks, it is working with the linux_V4l2wrapper.

One more question. If it would also work by just fetching the latest source and re-compiling the kernel, why is the need for a kernel module? Just curious because I try to have as less modules loaded as possible xD

(Sorry for the late reply.)

The module port is only for people that don't want to upgrade to -current or manually apply my V4L2 patch. (or upgrade to -stable once the patch has been merged there.)

I suggest make a new ports of FarSight's libmimic (http://sourceforge.net/projects/farsight/files/libmimic/libmimic-1.0.4/) and then modify any instant messager in ports tree, which supports webcamd, to link with libmimic.

@zeissoctopus

Please read here, I got a working webcam with libmimic in emesene

Edit:
Currently webcam converesations are not possible on at least aMSN, due to microsoft having blocked access to their SIP servers. (Please read the link above I posted, there is the original quote)

Hi, I think you use the port version. This version only use the bktr driver. If you want to use the version that will work with webcamd you will need a patched version. You could try:

http://www.rockafunk.org/patches_and_includes.tar.gz

This file include a lot of patches including Camserv. I hope this helps.

Camserv is a v4l1 program. If you have a uvc webcam you may have to start camserv like this:

LD_PRELOAD=/usr/local/lib/libv4l/v4l1compat.so camserv

Also you could try my configuration files.

wget http://www.rockafunk.org/camserv.tar.gz

Extract camserv.tar.gz and copy the directory to /usr/local/share.

cp -R camserv /usr/local/share/

In my configuration I have a little picture and some text. If you study camserv.cfg you can put your own picture and text there.

Good luck.

Quick recap now that there is a port obviating the need for some manual patches?

We need to install:
multimedia/cuse4bsd-kmod
multimedia/linux_v4l2wrapper-kmod
multimedia/webcamd (or the pwc driver depending on hardware)
multimedia/pwcview

Given the v4l2wrapper do we still need to install:
multimedia/libv4l and
multimedia/v4l_compat

But only for v4l1? Is that Intel or from China? Intel has the patent for video chips. I'm sure they have drivers to share they give them to Microsoft users frequently enough :) Linux has at least one driver.

You're talking cpio - it's easy to make a unix device for a stream. Then just cat /dev/cam1 >> socket_dumping_to_bitblit_to_video_card.

It's not rocket science. Likely this or that "cam" has other features (i.e., still frame, maybe even IP encoding) if you're getting the signal through yet another Intel chip. Most devices do this.

Anyhow call Intel and complain. It is their technology and they print on their Texas presses all camera chips. It's just an alteration dac chip. Still not amazing really.

OH i'm sorry I though chuchu did not say he offered new software only working with one break. He's trying to get it to work !!

Chuchu? These days I think people are logging in changing things so you continually have to jump through hoops of fixing what had already been working (ie, they make changes that aren't needed but break things). I'm sure some microsoft people have logged in to damage unix.

You might try getting the source and compiling. Often that installs itself correctly when "all else is broken".

Sorry I'm having difficulties with forum posting and was not paying attention and did stick my foot in my mouth.

I had said before Intel / Texas has patent for camera chips and makes them. Complain to Intel if you need a driver. They sure bend over to help Microsoft with them :)

If you don't have a driver that works there's a reason.

Using linux drivers ? Yea. But there is where things "seem to change around" allot.

You might need to get deeper in - run as loadable module that you can debug while you use it - put your own code in that prints what works / does not.

MAKE SURE THE BEEF WORKS - the IRQ/DMA/INP commands that talk to the camera. You might try it manually.

Another NOT SMALL detail. They keep changing the codes in the chips to "new versions". This causes drivers to fail.

Who always seems to have the drivers? Microsoft (and, hardly, sometimes Apple)
