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,

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.

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.

Hello,
I just make 3 abstractions ([float2symbol], [symbol2list] and [list2symbol]) based on the new objects [list fromsymbol] and [list tosymbol] from Pd 0.46. (maybe, it is certainly possible to symplify them, comments are welcome). So these abstraction are 100% pure Pd. They can be added in "list-abs" or "purepd" or "zexy/abs", i don't know ? ++

I forget to add [list-drip] from list-abs. ++

I answer to myself... [symbol2list] abstraction doesn't work as i expected because it outputs a list where numbers are unpacked as symbols. ++
