not able to build libv4lconvert on Ubuntu 16.04

not able to build libv4lconvert on Ubuntu 16.04

[Thomas Jenni]

Hi there !

I've tried to build libv4lconvert (ubuntu 16.04, 64bits) cloning the git.

After removing the first line of the Makefile in the libv4lconvert
directory (that was set to arm architecture), the problem was that it
didn't find "linux/videodev.h".

I tried:

sudo ln -s /usr/include/linux/videodev2.h /usr/include/linux/videodev.h

but that was the same.

I tried:

sudo ln -s /usr/include/libv4l1-videodev.h /usr/include/linux/videodev.h

and then it told me a lot things (that i don't understand):

In file included from /usr/include/x86_64-linux-gnu/asm/ioctl.h:1:0,
                 from /usr/include/linux/ioctl.h:4,
                 from ../libv4lconvert/libv4lsyscall-priv.h:41,
                 from log.c:21:
log.c:42:11: error: ‘VIDIOCKEY’ undeclared here (not in a function)
  [_IOC_NR(VIDIOCKEY)]        = "VIDIOCKEY",
...

Here's the complete log:
