I did

# apt-get install libVLC5
# cmake -C zm_conf.cmake -DENABLE_MMAP=yes .

Returns -- Optional libraries not found: cURL libVLC

OK, thanks again for your input. I made progress, but now I'm stuck for hours on this: zm_mpeg.cpp:(.text+0x59): undefined reference to `avcodec_encode_video2' I assume my libavformat headers are wrong. I have this: # dpkg -l | grep libavformat ii libavformat-dev 4:0.8.10-0ubuntu0.12.04.1 Developmen...

Thank you for that. I am always puzzled though. There seem to be a major conflict over how to compile from source. One way I see is this: root@host:~# git clone https://github.com/ZoneMinder/ZoneMinder.git zoneminder; root@host:~# cd zoneminder; root@host:~# ln -s distros/ubuntu1204 debian; root@hos...

I think I managed to compile this way: # cmake -C zm_conf.cmake -DENABLE_MMAP=yes . # make clean # make # make install (if updating run the update script, root user, no password) # scripts/zmupdate.pl --user=root --pass= # ldconfig *** Never mind, it's compiling now. I think I didn't have enough cof...

I'm having trouble figuring out how to compile a particular branch. I've tried several different things. # git clone https://github.com/ZoneMinder/ZoneMinder.git zoneminder; # cd zoneminder; # git checkout -b release-1.27 origin/release-1.27 # ln -s distros/ubuntu1204 debian; # dpkg-checkbuilddeps; ...

variable is not a string at /usr/local/lib/x86_64-linux-gnu/perl5/ZoneMinder/Memory/Mapped.pm line 113. I continue to be plagued with this error. I see the code here in Mapped.pm, I do not use this language and it's really foreign to me. Any clues what's wrong, what it's doing, and how do we fix it?...

Thanks, I will do that.
I guess you have to know these things when you're king.

nevermind.
Found on another forum: zmupdate.pl --user=root --pass=

That worked.

I am stuck on an error from zmupdate.pl mysqldump: Got error: 1044: Access denied for user 'zm'@'localhost' to database 'zm' when using LOCK TABLES I tried zmupdate.pl -u zm -p zm, but that didn't help. zm/zm are what I have listed as the db user and password according to my old zm.conf. I tried adm...

Yeah, this is all correct. My post is not intended to be a "fix", it is still a cry for help. And still unanswered.
Good news is that this morning I woke up to a working system for the first time in a month.

The stream dies. We restart the stream. I fail to see the problem with this strategy.

This is not my code, I'm coming in cold on this. That's why I've been asking for help to get it to work. It will take a long time for me to be comfortable with the code. Is this your function? I'm just grasping at straws here. Like I said in another post, I'm willing to put in the time to make it wo...

I found the root of the problem. zm_monitor.cpp (2675) there is a block if ( captureResult != 0 ) { // Unable to capture image for temporary reason // Fake a signal loss image capture_image->Fill( signal_check_colour ); captureResult = 0; } else { captureResult = 1; } So, if the stream fails, this b...

New troubleshooting information: I have determined that the problem is NOT network congestion, and it is NOT due to packet loss. ZM recovers from packet loss, I verified this up to 10 seconds. The problem is when the stream is reset by the camera. This is 100% repeatable and can be done in one secon...

In zm_ffmpeg_camera.cpp at line 215, we know we have a problem. "Unable to read packet from stream". The Capture function returns a -1. At this point, I think the zmc should terminate and reconnect the failed stream. But it doesn't. It just repeats the error until the log drive fills up. S...
