Libjpeg-turbo 1.0 beta Released!

[christophe_y2k]

Hello
That work under an Linux Gentoo update (64b)
for perf i say you in a couple of day
ok have 14-20% cpu usage with ZM v1.23.2 with standard jpeg
now have 3-10% cpu usage with ZM V1.24.3 With libjpeg turbo and +1 to +2 fps by ip camera

little procedure for gentoo (must adapt for you...)

# emerge --sync
# emerge zoneminder

configure it and when all are ok and work fine you can

(nb: i copy this procedure from gentoo bugzilla)
# emerge --unmerge jpeg-6b-r9
# emerge --unmerge jpeg-8b
# echo "=media-libs/libjpeg-turbo-1.0.1 **" >> /etc/portage/package.keywords
# mkdir /etc/portage/profile
# echo "media-libs/jpeg-6b-r9" >> /etc/portage/profile/package.provided
# echo "media-libs/jpeg-8b" >> /etc/portage/profile/package.provided
# emerge --pretend libjpeg-turbo
# revdep-rebuild

and install svn of zm:

# emerge SVN-Mirror

# svn co http://svn.zoneminder.com/svn/zm/trunk /usr/share/zoneminder

# cd /usr/share/zoneminder
# ./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --libdir=/usr/lib64 --with-libarch=lib64 --with-mysql=/usr --with-ffmpeg --with-webdir=/var/www/zoneminder/htdocs --with-cgidir=/var/www/zoneminder/cgi-bin --with-webuser=apache --with-webgroup=apache --enable-debug=no --enable-crashtrace=no --enable-mmap=no ZM_DB_HOST=localhost ZM_DB_NAME=zm ZM_DB_USER=zmuser ZM_DB_PASS=zmpass CXXFLAGS=-D__STDC_CONSTANT_MACROS

# make
# make install
# zmupdate.pl -f


Warning on gentoo libjpeg-turbo, break OpenOffice package (now resolved with recently gentoo update)

Have a probleme with scaling not work in montage view but don't know if that a svn bug

Scalling is ok in one cam view or event view
If you have an idea for that write me

Looks like zoneminder 1.25 on ubuntu 12.04 insists on using libjpeg.so.8.0.2 instead of libjpeg.so.62.0.0. I was unable to force zoneminder to use the older version modified with libjpeg-turbo (using the methods posted in this thread). However, I did find a precompiled .deb linked from http://pkgs.org/ubuntu-12.04/ubuntu-mai ... 4.deb.html

Direct Link

Code: Select all

wget http://archive.ubuntu.com/ubuntu/pool/main/libj/libjpeg-turbo/libjpeg-turbo8_1.1.90+svn733-0ubuntu4_amd64.deb
dpkg -i libjpeg-turbo8_1.1.90+svn733-0ubuntu4_amd64.deb
service zoneminder restart

Testing it out now, not sure if I really notice anything in terms of enhanced cpu performance...

Hi,

I'm on 12.04 as well, 32-bit, Virtualbox guest, 2 CPU out of quad Q6600 2.4Mhz, 900Mb RAM assigned

I stopped both Apache2 and Zoneminder (sudo service apache2 stop, etc) and per the library's page for my OS, I ran:

Code: Select all

sudo apt-get update

sudo apt-get install libjpeg-turbo8

With 6 cameras in Modect my utilization went from 85% user to 55% user. ZM load shows: 2.03.

Regards,
JR
