BUG: vloopback_motion.c compile fails

Compilation fails at the make stage, complaining that the storage sizes of vid_pic and vid_win are not known. This happens even following a clean download of the most recent trunk build.

[libv4l-devel includes a replacement videodev.h file]
/usr/include/libv4l1-videodev.h

Environment

Motion version:	trunkREV557
ffmpeg version:	0.11.1-1.1.x86_64
Shared libraries:	ffmpeg
Server OS:	OpenSuSE 12.1, 3.1.10-1.16-desktop, 64 bit.

Fix record

Modifying the config.h file replacing the code:

/* Define to 1 if you have the <linux/videodev.h> header file. */
#define HAVE_LINUX_VIDEODEV_H 1

with this:

/* Define to 1 if you have the <linux/videodev.h> header file. * /
/* #undef HAVE_LINUX_VIDEODEV_H */

Allowed me to compile properly. I am using trunk 557.

If you do not have videodev2.h on your machine I don't know if this will work properly for you.
