[FreeBSD 8/9] USB webcamd and video4bsd: Call for testing
Hans Petter Selasky
During the last couple of days I've spent some time to finish my webcam
daemon. My webcam daemon is basically an application which consists of
userspace Video4Linux USB webcam drivers and some uLinux glue code which links
with libc, pthreads and libusb. The webcamd talks to /dev/video_daemonX which
is provided by the video4bsd kernel module. There is full support for
mmap/read/write/open/close. poll is not supported.
Basic operation and idea:
/dev/video_daemonX is the interface for the webcamd. /dev/videoX is the
interface for the V4L application. The video4bsd transports all data between
these two devices. In the case the V4L application is using mmap, no data is
copied due to shared kernel memory buffer!
Licensing issues:
Effectivly the webcamd userland program becomes GPL'ed due to the V4L USB
drivers which are GPL licensed. Some files inside the webcamd remains BSD
licensed which allows for building similar BSD licensed daemons.
The rest of the code is BSD licensed.
Source code:
1) FreeBSD 8-stable
2) Apply the patch below and re-install libusb in /usr/src/lib/libusb:
http://p4web.freebsd.org/chv.cgi?CH=172876
http://perforce.freebsd.org/chv.cgi?CH=172876
3) Compile ulinux (webcamd + libv4l + pwcview) and video4bsd (must be checked
out in the same folder due to dependencies)
svn --username anonsvn --password anonsvn \
checkout svn://svn.turbocat.net/i4b/trunk/usbcam/video4bsd
make all install
kldload video4bsd
svn --username anonsvn --password anonsvn \
checkout svn://svn.turbocat.net/i4b/trunk/usbcam/ulinux
make fetch
make patch
make all
make install
# this will attach to the first detected webcam:
./webcamd
# this will try to attach to the given USB unit, interface and V4B unit.
./webcamd -d ugen4.1 -i 0 -v 0
# this will display webcam contents from /dev/video0 by default.
./pwcview/pwcview
Feedback and bug reports are welcome.
Yes, I am working on getting this into ports!
Known issues:
1) If you detach the USB webcam you need to manually restart the webcamd.
--HPS
Support: I will be available at #bsdusb on efnet during the day.

Hi,
Maybe this is related to a bug in the recent JPEG library. Try googling.
You can also try another mode:
webcamd -s vga
Or other commands. See webcamd -h .

Hi,
I was trying this driver with:
my webcam:
ugen7.2: <Lenovo EasyCamera vendor 0x046d> at usbus7, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=ON
my system:
FreeBSD starkiller 8.0-RELEASE-p2 FreeBSD 8.0-RELEASE-p2 #0: Tue Jan 5
21:11:58 UTC 2010
ro...@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC
amd64
When turn on the webcam:
Jan 10 16:13:25 starkiller root: Unknown USB device: vendor 0x046d product
0x09b6 bus uhub7
Jan 10 16:13:25 starkiller kernel: ugen7.2: <vendor 0x046d> at usbus7
when execute ./webcamd -d ugen7.2 -i 0 -v 0
Jan 10 16:13:29 starkiller root: Unknown USB device: vendor 0x046d product
0x09b6 bus uhub7
Issues:
To access /dev/video0 with a no-root user in operator group, I changed
permisions: chmod 0660 /dev/video0 manually
I can access using pwcview but I cant access from cheese, Do I something to
get this?
Thanks for this software, good work!!!

these drivers with Spook, a lightweight RTP/RTSP streamer originally for
Linux:
http://www.freshports.org/multimedia/spook/
Spook can use the V4L 1.x mmap() interface. I tried it with a one of
Luigi's ported drivers; it was not always stable, but it was able to
stream. It may be a good 'soak test' for the drivers.
As far as I know, the V4L2 API isn't in a BSD compatible form yet. This
seems to be needed to be able to deal with capture devices which can
read compressed frames from the device directly.
cheers,
Bruce

Hi again,
The JPEG library fix is here:
http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/137265
Try to "svn up" and build fresh sources. I've found and fixed some bugs.

Tested and working fine so far (I've only checked the bundled
pwcview application) with the builtin webcam of an Acer Aspire

Hi,
I think Andrew made a fixed port which you can test. The V4L sources has
changed since the last couple of days. The build error you are seeing has been
fixed in the latest SVN version of my code.

Bzzt, wrong. It will make no difference whatsoever; make.conf is
included by sys.mk before the Makefile itself is read, so the Makefile
overrides make.conf, not the other way around.

Do you have CFLAGS set in /etc/make.conf by chance?

I've tested on my webcam and it works here.
I have an USB Video Class webcam:
ugen2.2: <Vega USB 2.0 Camera. Vimicro Corp.> at usbus2, cfg=0 md=HOST
spd=HIGH (480Mbps) pwr=ON
This is the first time it works in FreeBSD! Thanks a lot!
Currently, it works with -s vga and -s cif. There are many other modes
supported by the webcam, but pwcview just does not support them. This
webcam supports at most 1280x1024, and the quality is clearly better
than 640x480.
There are some problems, however. First, when I start pwcview with an
unsupported mode, the content of the window is green, and I cannot
kill the process. Only after terminating webcamd can I terminate the
process.
Second, I cannot restart pwcview without restarting webcamd. At the
second time I start pwcview with -s vga, the window is green, and I
cannot kill it. The situation is similar to unsupported size.
I've also tried applications such as pidgin, skype and mplayer.
However no one successfully played from the webcam. I doubt it needs
some extra work.
I've changed pwcview a bit to keep the settings in internal variables
instead of fetching them every time. Else I cannot change most
parameters. Maybe the webcam only supports a certain set of setting
values, and use the nearest value after setting them.
Thanks again for the great work! It never caused any kernel panic, and
the programs are fairly stable.

I have tested this with CFLAGS=-g in /etc/make.conf
/usr/ports/multimedia/webcamd# make -dA
...
Global:CFLAGS = -g -I/usr/local/include
...
(cd /usr/ports/multimedia/webcamd/work/webcamd-0.1.0; if ! /usr/bin/env
SHELL=/bin/sh NO_LINT=YES PREFIX=/usr/local LOCALBASE=/usr/local
X11BASE=/usr/local MOTIFLIB="-L/usr/local/lib
-lXm -lXp" LIBDIR="/usr/lib" CC="cc" CFLAGS="-g -I/usr/local/include"
CXX="c++" CXXFLAGS="-g -I/usr/local/include" MANPREFIX="/usr/local"
BSD_INSTALL_PROGRAM="install -s -o root -g
wheel -m 555" BSD_INSTALL_SCRIPT="install -o root -g wheel -m 555"
BSD_INSTALL_DATA="install -o root -g wheel -m 444"
BSD_INSTALL_MAN="install -o root -g wheel -m 444" make -f M
akefile all; then if [ x != x ] ; then echo "===> Compilation
failed unexpectedly."; (echo ) | /usr/bin/fmt 75 79 ; fi; false;
fi)
...
Global:CFLAGS = -g
So CFLAGS is being properly passed to the
/usr/ports/multimedia/webcamd/work/webcamd-0.1.0/Makefile via the
environment but its getting overridden and causing the reported build error.

I've tested with recent ports.
pwcview works fine, both vga and sif
but skype still sees /dev/video0 but fails to play anything from it,
multimedia/cheese even does not sees webcam.
Is it supposed, or I am so unlucky ?
PS. microphone in cam work also as snd_uaudio pcm2

Thanks you for efforts!
I've tested it with

Hi,
During the last couple of days I've spent some time to finish my
webcam
daemon. My webcam daemon is basically an application which consists of
userspace Video4Linux USB webcam drivers and some uLinux glue code
which links
with libc, pthreads and libusb. The webcamd talks to
/dev/video_daemonX which
is provided by the video4bsd kernel module. There is full support for
mmap/read/write/open/close. poll is not supported.
Basic operation and idea:

I know what the problem is, and I will try to fix it in the next release of
webcamd.

You need to recompile these applications after installing libv4l. I have vlc
working with the new stuff.

Yes it is supposed to work, but you maybe need to tweak/rebuild the gstreamer
V4L2 code.

I am unsure whether I missed anything so here is what I did
csup to 8_RELENG
rebuild kernel & world
portmanager webcamd (which built video4bsd also)
kldload video4bsd
webcamd
webcamd -d ugen0.2 -i 0 -v 0
but I get
Cannot open /dev/video_daemonX. Did you kldload video4bsd?
this is the relevant part from dmesg:
video4bsd: /dev/video0..9, /dev/video_daemon0..9
ugen0.2: <vendor 0x046d> at usbus0 (disconnected)
uaudio0: at uhub0, port 2, addr 2 (disconnected)
pcm2: detached
ugen0.2: <vendor 0x046d> at usbus0
uaudio0: <vendor 0x046d product 0x08d7, class 0/0, rev 1.10/1.00, addr 2>
on usbus0
uaudio0: No playback!
uaudio0: Record: 16000 Hz, 1 ch, 16-bit S-LE PCM format
uaudio0: No midi sequencer
pcm2: <USB audio> on uaudio0
what am I missing? The device is supported on linux by the gspca driver.

Hi,
See:
usbconfig -u 7 -a 2 dump_curr_config_desc | grep -i class
To figure out what interface class your USB device is using.

Hi,
Maye that is a bug in /usr/ports/multimedia/libv4l which is external code,
where the printout comes from. Maybe the code should be more fault tolerant.
Try googling first.
Can you dump the USB descriptors of your device?
usbconfig -u X -a Y dump_device_desc dump_curr_config_desc

Interestingly skype does not seem to detect the webcam even though it claims
to support v4l
