xawtv and channels on bt878

yavan · Post by **yavan** » Tue Oct 23, 2007 11:02 pm

Hi, i have zm up and running the way i want it, but i need to be able to see real time stream from my cameras on the gui desktop.

i was thinking to use xawtv but here is my problem:
xawtv or kdetv scannes all the channels of my bt878 very fast in a loop and i can not get to either
1. make it scan very slow for i.e 30sec each channel, so it like changes between cameras each interval of time
2. have 4 instances of xawtv and make each one of them show only one channel. so i end with 4 open windows of xawtv

user@linux-102:~> xawtv4 -hwconfig
This is xawtv 4.0-pre, running on Linux/i686 (2.6.18.2-34-default)

device configuration "BT878 video (ProVideo PV143)":
bus = PCI:0000:00:0a.0
video = /dev/video0
vbi = /dev/vbi0
dvb = [unset]
sndrec = [unset, using default]
sndplay = [unset, using default]
mixer = [unset, using default]
control = [unset]

device configuration "xv port: 65 (video4linux)":
bus = [unset]
video = port:65
vbi = [unset]
dvb = [unset]
sndrec = [unset, using default]
sndplay = [unset, using default]
mixer = [unset, using default]
control = [unset]

any tips on how to solve the problem are welcome

A bt878 chip can only view one input of it's four at a time, ZM works by scanning the imputs and taking a capture of each image, on each pass. If you affect the way ZM scans the card, you affect your recorded images as well.

Use shmlib which is a third party app to view cameras in ZM on the same machine.

thanks for the explanation, i have downloaded it but can not find any INSTALL document on how to install it
do i have to compile it with configure > make > make install ?
what are my dependencies GCC ver, x11 etc ?

this is what i get when i am trying to run xlib_shm:
linux-102:/home/user/Documents/xlib_shm-0.6.3 # ./xlib_shm
./xlib_shm: error while loading shared libraries: libmysqlclient.so.12: cannot open shared object file: No such file o

and this is what i have installed:
linux-102:/home/user/Documents/xlib_shm-0.6.3 # locate mysqlclient
/usr/lib/libmysqlclient_r.so.15
/usr/lib/libmysqlclient_r.so.15.0.0
/usr/lib/libmysqlclient.so.15
/usr/lib/libmysqlclient.so.15.0.0
/usr/lib/mysql/libmysqlclient_r.so.15
/usr/lib/mysql/libmysqlclient_r.so.15.0.0
/usr/lib/mysql/libmysqlclient.so.15
/usr/lib/mysql/libmysqlclient.so.15.0.0

any idea what do i have to do in order to be able to run the xlib_shm ?

The compiled version on his website is old, and compiled against an old mysql client. I was able to get it working on Edgy by installing libmysqlclient.so.12 but by Feisty that would no longer work. You will need to compile it yourself against your system if that is the case for you.

ok i have recompile xlib_shm on my open suse 10.2 i586 box
and this is what i get:

linux-102:/home/user/Documents/xlib_shm-0.6.3 # make clean
rm -f *.o *.core xlib_shm
linux-102:/home/user/Documents/xlib_shm-0.6.3 # make
gcc -c xlib_shm.c -I/usr/X11R6/include
gcc xlib_shm.o -L/usr/X11R6/lib -lXv -lXext -lX11 -lmysqlclient -Wl,-rpath=/usr/X11R6/lib -o xlib_shm
linux-102:/home/user/Documents/xlib_shm-0.6.3 # ./xlib_shm -m 1
xlib_shm viewer for zm 1.22.3 version 0.6.3
Can't open /usr/local/etc/zm.confSegmentation fault

whats wrong ?

yavan · Post by **yavan** » Thu Oct 25, 2007 9:34 pm

ok i kind of resolved the problem
i did not have /usr/local/etc/zm.conf
so i try creating ln -s zm.conf /usr/local/etc/zm.conf
but it did not work for me

so i just cp zm.conf /usr/local/etc/

and it works

but now i see it B/W with lines and the stream is at the same speed as the mozilla montage feature

how to progress from here ?

if more info regarding my hardware is required please let me know
again my problem now is that i see the stream form the cameras (2) in B/W and with lines across the picture
this is how it looks:

During this time you can see clear streams from a browser on another system, correct? In other words, yous ZM install is functioning? If so, you are out of my realm of knowledge. I just played with xlib-shm. Never got to know it that well.

how do i check i have support for vga adapter in xvideo rgb 32 ?

muzyk10 · Post by **muzyk10** » Sat Oct 27, 2007 11:08 pm

are U using autodetect modprobe for bt878 or maybe it is 77 setting?
If autodetect try this 77 (shuld be /etc/modprobe.conf or similar, dont know Suse)

yavan · Post by **yavan** » Sun Oct 28, 2007 7:39 am

the card was autodetected by SuSe so i asume it is autodetected i will try to change the setting manually
and check it out, you are correct regarding the path.
just for my knowledge what is the difference ?

one more question do i have to see a line in my xorg.conf file regarding xvideo enabled and rgb32 ?
because i do not see one

yavan · Post by **yavan** » Sun Oct 28, 2007 4:31 pm

this is what i have found within modpobe.conf regarding bttv:
# options bttv pll=1 radio=0 card=0
# options tuner type=0
# options msp3400 once=1 simple=1

# install bttv /sbin/modprobe --ignore-install bttv && { /sbin/modprobe -k tuner; /sbin/modprobe -k msp3400; }
#

what do i have to change here ?

also this is my dmesg | grep bttv
