webcamserver

[ralcocer]

I am trying to compile webcamserver but I get the error: Could not find linux/videodev.h, tried the headers, V4l, gsstreamer, mjprg-streamer, the camera works wxcam and with skype .

Thanks in advance

Try adding the "crippled sources" module that corresponds to your arch/version. The linux kernel headers are stripped by default and it looks like webcamserver needs to compile against them.

Did that already but it does the same thing.

Looks like videodev.h is related to an old API that isn't inside the kernel anymore. To preserve functionality, I think they copied that header information into a header in the v4l-utils package. link: http://www.mail-archive.com/linux-media ... 27528.html

Please install v4l-utils (may have to get it from slackware and convert it to a module if it's not in the ppm repo), then create a symlink to the v4l header, where the .configure script is looking for it:

Code: Select all

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

Now you should be able to build as normal.

good luck!

I have had the same problem with compiling mjpg-stream. Check and see if you have videodev2.h

Code: Select all

ls -l /usr/include/linux/videodev2.h

If you have a videodev2.h then sym link a videodev.h to it

Code: Select all

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

Check and make sure everythings OK like I have here

Code: Select all

root@darkstar:~/builds/mjpg-streamer/mjpg-streamer# ls -l /usr/include/linux/videodev*
lrwxrwxrwx 1 root root    56 Jun  9 21:05 /usr/include/linux/videodev.h -> /usr/src/linux-3.6.11-20130520/include/linux/videodev2.h
-rw-rw-r-- 1 root root 99631 May 17 14:19 /usr/include/linux/videodev2.h

IYou should then be able to compile unless something else I don't know about is wrong

I found this script and I was able to run the webcamserver without errors, neeeds v4l:

Code: Select all

#!/bin/sh

SERVER_BIN=webcam-server
LOCK_FILE=/var/lock/$SERVER_BIN
RTRN=0
#OPTIONS='-v -g 320x240 -p 8888 -c yourwebcam.com'

start() {

[ -f $LOCK_FILE ] && echo "$SERVER_BIN already started"
[ -f $LOCK_FILE ] && return

echo -n "Starting $SERVER_BIN: "
export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
nohup $SERVER_BIN $OPTIONS > /dev/null 2>/dev/null &
RTRN=$?
[ $RTRN -eq 0 ] && echo Started! || echo FAIL
[ $RTRN -eq 0 ] && touch $LOCK_FILE
}

stop() {
[ -f $LOCK_FILE ] || echo "$SERVER_BIN is not running"
[ -f $LOCK_FILE ] || return
echo -n "Stopping $SERVER_BIN: "
pkill -f "$SERVER_BIN $OPTIONS"
RTRN=$?
rm -f $LOCK_FILE
[ $RTRN -eq 0 ] && echo Stopped! || echo FAIL
}

case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
*)
echo "Usage: $0 {start|stop|restart}"
RTRN=1
esac

exit $RTRN
