I just checked 0.93.3 out on a Ubuntu 12.04 32bit system.
And it suffer from the same issue reported in [1].
Note that I also give a workaround there to build DV plugin despite
of the
issue.

hi,
if you can `dvgrab` your camera, then your camera has a DV link
interface.
`dc1394` is not the same and it's intended for industrial IIDC
compliant
cameras.
You *cannot* grab a DV camera with the DC1394 library, see [1].
To use your DV camera with Gem, you need either to compile the
`videoDV4L`
plugin or to use a V4L wrapper for DV camcorder [2].
You can also try the Unicap plugin, but I'm not sure if it supports
DV
cam.
Unfortunately, I'm unable to build the videoDV4L plugin on Ubuntu
14.04.
`./configure` says DV plugin is enable (but is it the same ?) but
the is
no gem_videoDV4L.so.
I'll file a bug report for this.
Maybe this plugin works in 0.93.3 release, I never tried it before.
if you build Gem yourself, please consider the use of the git repo
[3].
there are *lots* of improvements since 0.93.3 release.
The latest build system update will give you more information about
which
plugins are actually enabled when configuring.

Hi,
im running a clean install of Ubuntu 12.04, with Puredata 0.43.0-4
from
Ubuntu repos, with a compiled Gem-0.93.3.
Configure output of Gem shows:
capture-support
use PLUGINS : yes
use v4l : yes (libv4l)
use v4l2 : yes (libv4l)
use ieee1394 : yes ( libdc1394 )
When i connect the dv device i see in dmesg:
[14522.765477] firewire_core: phy config: card 0, new root=ffc1,
gap_count=5
[14522.765695] firewire_core: phy config: card 0, new root=ffc1,
gap_count=5
[14523.269924] firewire_core: created device fw1: GUID
002011010f002781,
S400
Im able to dvgrab from the device without problems.
When i create pix_video i see in console:
[pix_video]: backend #0='v4l2' : v4l2 analog
[pix_video]: backend #1='v4l' : v4l analog
[pix_video]: backend #2='dc1394' : dc1394 iidc
When i send [driver dv( to pix_video:
videoctl: driver dv
[pix_video]: could not find a backend for driver 'dv'
When i send [device /dev/fw1( to pix_video:
videoctl: device /dev/fw1
Cannot open '/dev/fw1': 25, Inappropriate ioctl for device
videoDC1394: no cameras found
I try to set [driver 2(:
videoDC1394: no cameras found
I send now [device /dev/fw1( to pix_video:
videoctl: device /dev/fw1
videoDC1394: no cameras found
and so on ..
The device is there (i chmoded it to 777 to make sure)
# ls -la /dev|grep fw
crwxrwxrwx 1 root root 251, 0 Aug 10 19:41 fw0
crwxrwxrwx+ 1 root video 251, 1 Aug 10 23:43 fw1
this is my kernel:
3.2.0-65-lowlatency #68-Ubuntu SMP PREEMPT
Does anyone have any idea what could be wrong ? I guess it must be
sth
stupid and trivial..
thx & regards,
gnd/
