Heh, got me!  Mea culpa, I scanned the output of ./configure and missed 
the reminder for configure.log (which, believe it or not, I generally 
try to parse when I experience compile probs).

Now that you've pointed me to the relevant line I've tracked the 
situation down a bit further.  My semi-educated guess is that the v4l2 
interface is not being detected because recent mplayer CVS cannot find 
videodev2.h:

 ============ Checking for Video 4 Linux 2 TV interface ============

#include <stdlib.h>
#include <linux/types.h>
#include <linux/videodev2.h>
int main(void) { return 0; }

cc     -o /tmp/mplayer-conf-24845-10019.o /tmp/mplayer-conf-885-10019.c
/tmp/mplayer-conf-885-10019.c:3:29: linux/videodev2.h: No such file or 
directory

ldd /tmp/mplayer-conf-24845-10019.o
ldd: /tmp/mplayer-conf-24845-10019.o: No such file or directory

Result is: no

Which is strange because the v4l2 headers are right there in the same 
kernel source directory 
(/lib/modules/2.6.12-1.1381_FC3/build/include/linux) as videodev.h, 
which mplayer CVS does find:

============ Checking for Video 4 Linux TV interface ============

#include <stdlib.h>
#include <linux/videodev.h>
int main(void) { return 0; }

cc     -o /tmp/mplayer-conf-24845-10019.o /tmp/mplayer-conf-885-10019.c

ldd /tmp/mplayer-conf-24845-10019.o
    linux-gate.so.1 =>  (0x00844000)
    libc.so.6 => /lib/tls/libc.so.6 (0x0069b000)
    /lib/ld-linux.so.2 (0x00681000)

Result is: yes

Sooo, having tracked it down a bit more, I find myself halted once 
again.  How would I go about getting recent mplayer CVS to be able to 
find videodev2.h?  Is there supposed to be a videodev2.ko driver in 
addition to videodev.ko?  Or is Fedora Core not playing nice with 
mplayer CVS?  Thanks for the help folks.
