videoDV4L doesn't build while DV plugins is enabled by configure

[avilleret]

on Ubuntu 14.04 with :

sudo apt-get update
sudo apt-get install libdv4-dev libraw1394-dev libiec61883-0 
git pull
./configure

I got :

  capture-support
    use PLUGINS      : yes
    use v4l              : yes (libv4l)
    use v4l2             : yes (libv4l)
    use ieee1394         : yes (libdc1394)
    use DV               : yes
    use Unicap           : yes
    use Video-for-WinDOS : no
    use QuickTime        : no
    use AVFoundation     : no

But after make there is no gem_videoDV4L.so.

It appears that HAVE_LIB_LIBIEC61883 is not defined while the library is well installed.
If I commented the lines 10 and 15 of plugins/videoDV4L/Makefile.am then ./configure && make I have a gem_videoDV4L.so.

But I didn't test it since I have no DV camcorder under the hand.

FYI the full ./configure log is here : https://gist.github.com/avilleret/9457535e645aa6806425

note that https://github.com/umlaeute/Gem/tree/0.93.3 on Ubuntu 12.04 also suffers from this issue

Hi, i tested with Gem 0.93.3 on Ubuntu 12.04. In plugins/videoDV4L/Makefile.am the lines that had to be commented were 8 and 12. The libs for the plugin were built. I tested with a Canopus TwinPact 100 scan converter and DV input works flawlessly! I'm gonna test Gem from git.

videoDV4L depends on libiec61883-dev (not just libiec61883-0).

if the header <libiec61883/iec61883.h> is not found by configure, it should not claim that DV is supported (so there is indeed an - albeit minor - bug)

it's unclear to me how @gndgnd was able to produce a working build.

[umlaeute]

the bug in configure should be fixed with 74b5091

[avilleret]

yes it is fixed (at least for me) but I don't try it since I don't have DV camcorder
thanks for that
