[craver84]

hi everyone,
I'm reinstalling ubuntu intrepid again followin the guide of jsylvia007
I still have problems:

first of all

Code: Select all

garda@Byakugan:~$ sudo echo "/usr/local/lib" > /etc/ld.so.conf.d/ffmpeg.conf 
bash: /etc/ld.so.conf.d/ffmpeg.conf: Permission denied

???
so I did not do this part

Code: Select all

   echo "/usr/local/lib" > /etc/ld.so.conf.d/ffmpeg.conf
   echo "LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH" >> /etc/bash.bashrc
   echo "export LD_LIBRARY_PATH" >> /etc/bash.bashrc

   ldconfig
   reboot

I installed ffmpeg from SVN but when I try to compile zm

Code: Select all

_rtsp.o zm_rtsp.cpp
zm_rtsp.cpp: In constructor ‘RtspThread::RtspThread(int, RtspThread::RtspMethod, const std::string&, const std::string&, const std::string&, const std::string&, const std::string&, const std::string&)’:

I

can you help me please?

[craver84]

wow resolved!


nano -w src/zm_rtsp.cpp
don't change line 183 to:

Code: Select all

   
         mFormatContext = av_ alloc_ format_context(); 

but to

Code: Select all

         mFormatContext = av_alloc_format_context();

So there is a bug where it is putting a space? You should definitely report that!

[jsylvia007]

I'm posting from my Blackberry, so I'm sorry if the format gets messed up.

Craver84 found a typo in my guide, I'll look into that and fix it.

Also, punk_ecas, I will try what you suggested about removing those libraries. What you say makes perfect sense. I can't believe I missed that!!

Also, that guide was mean to be run as root, hence no "sudo" before many of the lines. Which is why you had a peoblem with one of the echo lines.

[jsylvia007]

Ok. I've updated my guide to remove the 3 packages provided by ffmpeg, and also removed the typo with the av_alloc_format line.

I'm starting from scratch on a Virtual Machine. I'll report back.

I'm going to try using the SVN ffmpeg first, then i'll try the other version.

SUCCESS!!! I've updated my guide as to how it works using the current SVN of FFmpeg and the SVN of ZoneMinder.

No older versions needed. I'm going to test this out on my production system, but look for the post below this one to see the complete guide start to finish.

[jsylvia007]

Here is my setup, exactly as I am doing it. No changes, no deviations.

I've added this guide to the Wiki as I am happy now after 10 complete installs that this works.

Ubuntu 8.10 Vanilla 32bit (with FFmpeg SVN, ZoneMinder SVN, jscalendar-1.0, cambozola-0.7)

Again, this is meant to be installed on a FRESH install of 8.10 with no modifications. Also, this guide is meant to be run as root, as such I have left out all the 'sudo' prefixes.

Please try and let me know your success. I've installed this way 3 times from scratch on a virtual machine, and I think this guide is now complete.

Followed this how to and everything works as promised even the ffmpeg part !

Just a couple of suggestions - during zm config it complained about not having mime:lite installed which is required for e mailing events.

This is a useful feature should the zm box go down or get stolen !

Secondly are you sure about the sysctl.conf settings ?

I was under the impression that kernel.shmall refers to the number of 4k pages in kernal.shmmax

Thus I have set mine to

kernel.shmall = 262144
kernel.shmmax = 1073741824

I'll now go and delete my initial attempt at a how to as yours is so much better.

[jsylvia007]

I've updated my Wiki post to reflect MIME::Lite. Great catch!!

Also, no, to be honest, I have NO IDEA WHATSOEVER about the kernel settings. Somewhere on the forums, people have discussed calculations and an excel worksheet.

I dont really know what the correct Kernel parameters should be. From my understanding its also dependent on the amount of physical memory.

[jsylvia007]

Timf: Also could you please put a link to the wiki page in the 1st post and change the title to include [SOLVED]

Also, I'd like to thank everyone in this thread, especially Timf, because his guide was the one that helped me to get mine started.

I found this link in the wiki:

http://www.zoneminder.com/wiki/index.ph ... solutions.

This post seems to recommend that you use the following for kernel.shmall:

Physical Memory * 1024 * 1024 / 4096

For my 6GB I would use ((6000 * 1024 * 1024) / 4096) = 1536000

For kernel.shmmax, they recommend what seems to be 1/2 of your physical memory converted to bytes, so for me that would be:

kernel.shmmax = 3221225472

Thoughts? I'm going to update the Wiki with that link and the link to this post.

I've tried using your excellent instructions, but on Jaunty, and I get the following errors

This is similar to the messages I was getting on my much abused Hardy system.

Any ideas would be greatly appreciated

Thanks

I'll setup a test VM and see what I can find. My guess is that there is still a dependency up stream with bugs because Jaunty hasn't been released yet.

[nickmcg]

Thanks - I had very similar errors on Intrepid too - I'm wondering if it could be my memory seetings.
I have 4 Gb physical ram, and the zmu gives

more ... this seems to be a palette problem - if I set the capture palette to yuv, I get lots of pretty colours at 12fps. it looks like an untuned (analog) tv picture, the image is not visible at all, although the timestamp shows up

I've managed to work rounf the problem - it seems to be a problem with the logitech webcam & zoneminder.

I used mjpg_streamer as documented in these two threads
http://ubuntuforums.org/showthread.php?t=882863
http://www.zoneminder.com/forums/viewtopic.php?t=12082
and everything works really well.

You can now add to the wikki that the instructions in the guide work for Jaunty!

Thanks for your responses

Nick
