[MPlayer-users] CVS compile tv-v4l2 input driver not detected/enabled

[Barton Bosch]

Hey List, apologies in advance if this message ends up double posting -- 
seems like there's some weird prob with my messages propagating to the 
list.  Sent this email a few days ago and have been waiting patiently 
but so far no soap.

In any case CVS compilation still fails to detect the tv4l2 device as 
detailed below. In the meantime I dug a little deeper and ran:

	grep -r videodev2.h


on the CVS main directory and found only the #include 
<linux/videodev2.h> in the tvi_v4l2.c file.

My knowledge of C is *very* limited but comparing the videodev2.h header 
include in tvi_v4l2.c with the videodev.h include in tvi_v4l.c doesn't 
reveal any difference.  A little help here?  TIA.

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.
