Alright, I had a moment of opportunity so I ran the same test described in the libjpeg-turbo readme file. The following results were run on a freshly built 64bit Ubuntu 10.04 System which uses an Athlon 3300+ cpu: dvr@ubuntu-dvr:~$ export LD_LIBRARY_PATH="" dvr@ubuntu-dvr:~$ time cjpeg tes...

That's a good point about different jpeg code paths... If you are using a capture device with a V4L driver that natively supports the card's hardware capabilities, then I would tend to agree with your speculation. You might want to send dcommander a message through the Sourceforge project website to...

I don't have a 64bit Ubuntu machine in front of me at the moment to verify, but I think your library path should read /opt/libjpeg-turbo/lib64 not /opt/libjpeg-turbo/lib. According to the readme file, here is the recommended way to test libjpeg-turbo: export LD_LIBRARY_PATH=/opt/libjpeg-turbo/{lib}:...

I haven't tried the .deb file myself, but I would expect it to operate the same as when compiling from source.... namely, it installs itself under its own folder and doesn't overwrite your existing libjpeg library. Consequently, if you want to use the libjpeg-turbo library instead of the default, yo...

I read your post... thought about it... I can't say I know what the issue is, but in light of no other responses here is what I would do if I were in your shoes. You could find out if it is a permissions problem by simply executing: sudo chown apache:apache -R /var/www/html Although my guess is that...

The author now has .deb files available for download on the libjpeg-turbo project website. That will be your best bet.

This should do it: sudo yum install perl-Module-Load If you have not already, I recommend you read the installation instructions for Zoneminder on CentOS in the wiki and verify you are not missing additional prerequisites. Simplest thing to do would be to just copy and paste the "yum install&qu...

The following is one example, specific to Zoneminder, of what dcommander is saying. Find the line in your /etc/init.d/zm script that says "$command start" and place the following just prior to that. For 64 bit systems: export LD_LIBRARY_PATH=/opt/libjpeg-turbo/lib64:$LD_LIBRARY_PATH For 32...

Some random thoughts... Perhaps you have tried this already, but what happens when you try to configure Zoneminder w/o the --with-fmpeg parameter? On my system anyway, Zoneminder seems to find ffmpeg w/o any help. Also, here is where avformat.h is on my system: /usr/local/include/libavformat/avforma...

I'm running CentOS 5.4 and the following has worked well for me: Remove any existing versions of ffmpeg first. e.g. sudo yum remove ffmpeg ffmpeg-devel cd svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg cd ffmpeg ./configure \ --enable-gpl \ --enable-shared \ --enable-pthreads \ --enable-nonfr...

Works like a champ on latest svn, revision 3033.

Thanks genanr!

The link I was referring to is this one:
http://sourceforge.net/projects/libjpeg-turbo/files/

The author has recently moved most everything from the previous location over to sourceforge.

At this location, the latest version appears to be 0.90.

Eureka! Got it. But before I show the steps I took to roll my own, you probably just want to read this thread as the author now has precompiled binaries available for both rpm and deb based systems: http://www.zoneminder.com/forums/viewtopic.php?p=60023#60023 If you are interested in doing things th...

The libjpeg-turbo website only shows version 0.90 available for download, rather than 1.0. Will 1.0 be posted soon or is 0.90 really the latest version?

Arecont makes some very high resolution cameras. The images are great, but as already mentioned you have to watch the bandwidth and cpu usage. I wouldn't expect Zoenmidner to be the limiting factor in how many mega pixels you can have or how many cameras you can use at once. The limiting factor will...
