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. + A [1] : http://damien.douxchamps.net/ieee1394/libdc1394/faq/#Can_I_use_it_for_my_DV_camcorder [2] : https://sourceforge.net/projects/dv4l.berlios/ [3] : git://git.code.sf.net/p/pd-gem/gem -- do it yourself http://antoine.villeret.free.fr 2014-08-10 23:55 GMT+02:00 <[email protected]>: > 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 ?
