firewire avc1394 camcorder to v4l for ekiga and cheese

(this is detailed and lengthy because i couldn't find anything in arch that discussed it -- hopefully now searchers will have a jump point]

the camcorder is attached via firewire from pcmcia

i think i have all the modules

these devices exist

However, ekiga (which correctly identifies the sony dcr-hc32 on auto detect) only shows a green screen and not the usual broken camera bouncy thing

this is apparently a known bug in ekiga  2.0.11 (http://www.nabble.com/ekiga-2.1.0-svn.- … 81873.html)
somewhere else there was also concern with pwlib plugins. Other distros do pwlib-plugin type packages. arch doesn't?

$pacman -Qi pwlib                                                           ~
Name           : pwlib
Version        : 1.10.10-2
...

$ pacman -Ql pwlib|grep plugin 
pwlib /usr/include/ptlib/plugin.h
pwlib /usr/include/ptlib/pluginmgr.h
pwlib /usr/lib/pwlib/devices/sound/alsa_pwplugin.so
pwlib /usr/lib/pwlib/devices/sound/oss_pwplugin.so
pwlib /usr/lib/pwlib/devices/videoinput/avc_pwplugin.so

pwlib /usr/lib/pwlib/devices/videoinput/v4l_pwplugin.so
pwlib /usr/share/pwlib/make/plugins.mak

Either way, i'd like to also use gnome's cheese (just for fun) or potentially skype video. Using the minidv camcorder as a v4l device would enable this and hopefully work around the ekiga bug.
It seems there are a few choices to do this. None of which I could get to work.

How can i use vloopback to use my firewire cam as a V4L device ?
Load vloopback
  modprobe vloopback

You need to use Coriander and set on services tab V4L
And then you will have a V4L in /dev/video1.

but this won't work for this case (though i did build it, and updated the out of date lib{raw,dc}1394. I downgraded before trying the other options.

http://damien.douxchamps.net/ieee1394/coriander/ wrote:

However, any cameras in which you can insert a video tape (camcorders,...) will NOT work with coriander. These cameras record compressed DV video on the tape, while the IIDC specify uncompressed, on-the-fly video flows. If you wish to use a camcorder you should have a look at Kino instead.

so the choices seem to be

3.  First you have to attach your camcorder to your firewire port and swith it on. Now start dv2vloopback with this:
      ./dv2vloopback /dev/video0 352x288x24 25
      The first parameter is the video device that will be used (it modprobes vloopback and by default the virtual device is in /dev/video0 so no problem), the next three parameters are the width, height and color depth and the last parameter is the frames per second.

Both of the potential solutions require vloopback, which is in the aur (vloopback 1.1rc1).

$ yaourt -S vloopback
...
$ sudo modprobe vloopback
$ lsmod |grep vloopback
vloopback              12896  0 
videodev               26880  1 vloopback

The first choice (dc1394_vloopback) is part of the libdc1394 package which is already installed. So its a good one to start with.

$ dc1394_vloopback                                                           ~
unable to start camera iso transmission

$

I have no idea what this means, but because it has an option to run as a daemon, i'd imagine it is suppose to lock up the terminal instead of exit. 

$ dc1394_vloopback --video1394=/dev/dv1394/0
unable to start camera iso transmission
: Success
$ dc1394_vloopback --video1394=/dev/dv1394/0 --width=720 --height=480

$ dc1394_vloopback --video1394 /dev/dv1394/0 --width 480 --height 720
unable to start camera iso transmission
: Success
$ dc1394_vloopback --video1394 /dev/dv1394/0 --width 720 --height 480
unable to start camera iso transmission
: Success

no luck trying different options. onto the other potential solution

dv2vloopbak is not in the aur. So i tried a quick pkgbuild. (didn't submit it, because it doesn't work for me)

the command, both with and wihtout sudo, continue until ctrl+c kills it.


Somewhere someone has to have a minidv camcorder working with v4l!? anyone doing it on arch -- or anyone see a glaring mistake?

Thanks

Re: firewire avc1394 camcorder to v4l for ekiga and cheese

Hello, I have a problem with installation of dv4l. I have installed vloopback from svn, since I have the latest kernel.

After ./configure I do:
