Hi,
I wanna save the video from ip camera.
however, I received an error message below:

[swscaler @ 0x7fde2c001d80] deprecated pixel format used, make sure you did set range correctly
[mpeg4 @ 0x7fde2c0018e0] intra_quant_bias = 0 inter_quant_bias = -64

Here's my code :
string camera2 = "rtsp://192.168.0.10/profile2/media.smp";
AVInput test2("test2", camera2);
app.addThread(&test2);

VideoParms videoParms( 640, 480 );
AudioParms audioParms;
MovieFileOutput movie( test2.cname(), "/transfer", "mp4", 100, videoParms, audioParms );
movie.registerProvider( test2 );
app.addThread( &movie );

Please let me know which part did I make mistake.
Thanks.

Sorry to do this here, but I'm not sure where else to ask.

Your project is C++ and cross-platform. It uses cmake for building on each system. I am starting a project with a similar set of properties. I would like to know what IDE you use and does it create the cmake files for you and maintain them? Also, how do you easily integrate the submodules into the build as static libraries?

@web2wire , I'm going to start tinkering with https://github.com/node-ffi/node-ffi too replicate stater-example in NodeJS and learn how stuff works here.

Would it be possible for you to create a single library, maybe something like libozoneserver.a as part of the build process?

This should in in addition to the API docs - which is really, a deeper device.

a) figure out a way not to build ffmpeg each time
b) reduce noise on slack

I tried to run the examples through the docker images: https://hub.docker.com/u/web2wire/

However, I wasn't able to reproduce the same results of the page: http://demo.ozone.network:9280/demo.html

Step-by-step this is what I did:

$ docker pull web2wire/ozonedev
$ docker run -it web2wire/ozonedev /bin/bash
container$ ./bootstrap-ozone.sh
container$ cd demo
container$ ./run-demo.sh

and this was the output:

I notice the files on /ozonebase/server/src/examples/ but I'm not sure how to access starter_example.html from my host browser...

I hope someone can assist me on solving this, so I can be able to try oZone

I get a lot of errors, but the rest of them might be a domino effect. The first error is:

/home/phire/ozonebase/server/src/base/../libimg/libimgImage.h: At global scope: /home/phire/ozonebase/server/src/base/../libimg/libimgImage.h:276:28: error: expected identifier before numeric constant enum { CHAR_HEIGHT=11, CHAR_WIDTH=6 }; ^

It seems the newer gcc libraries now define a CHAR_WIDTH and CHAR_HEIGHT in the standard headers. I would just rename them, but am unsure how to find all of the references in all of the files to do so.

We should create man page documentation of some sort. Since we are not distributing an executable, other than example programs, there is some question as to how to name it.

I'm looking at ffmpeg's manpage documentation and it looks like they've created the following man pages, which follow the names of their libraries:
ffmpeg-scaler
ffmpeg-resample
ffmpeg-codecs
ffmpeg-devices

If we followed that format, our project should have the following man pages added:
ozonebase-base (if it can be used by third parties)
ozonebase-consumers
ozonebase-encoders
ozonebase-libimg
ozonebase-libgen
ozonebase-processors
ozonebase-protocols
ozonebase-providers

or perhaps oz-libname for short

Start with http://dlib.net/face_detection_ex.cpp.html
and go from there

Code uses custom counted pointers, pthreads and other functions that are native in more recent version of C++. Suggest migrating to C++11.

Also quite a lot of warnings needs to be tidied.

should put in some safeguards to return an error or wait till init is done but not crash

need to make sure we are compliant with ffmpeg licensing https://www.ffmpeg.org/legal.html
In other words, we need to be able to git clone and build our own ffmpeg lib with the right compile options as per the url above. This will also avoid the endless loops of diff. host system ffmpeg versions and issues.

I vote to remove Rtmp as a protocol handler- I think its pretty much dead as of today. Comments?

Hi, I downloaded ozone on my ubuntu rn.
it's bit confused few things to run ozone for the first time.
I compiled and ran starter_example, then running html file.
Thus, it is failed to load video sources from sftp.
To set the $scope.baseurl from html file, which location should I exactly put it in?
For example, if my linux server ip is 192.111.23.231, is it correct to put this ip address?
or adding the location that "./starter_example" stored?

Please, let me know the details
Thanks

I noticed this error while compiling and it shows up in your automated compiles as well. Is this going to cause any issues for the nvrcli sample or any custom apps?

For @web2wire:

We need to modify ozone code to work with open264 and not x264. I suspect the problem lies in the av_ apis used in ozFfmpeg.cpp but don't know enough to change it.

trying to write an mp4 file for events produces

Jul  6 20:08:25 ubuntu nvrcli[22863]: FAT [Could not open video codec]

Why open264? Using open264 doesn't require --enable-gpl with ffpmeg. License & faq.

Steps to reproduce:

a) Build open264, release 1.5

git clone https://github.com/cisco/openh264.git
cd openh264/
git checkout openh264v1.5
make; sudo make install

b) Build ffmpeg with open264

git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
git checkout release/2.8
./configure --enable-shared --enable-libopenh264 --extra-ldflags=-L/usr/local/lib
make; sudo make install

c) Try to create an mp4 file - write a simple example, or use nvrcli

Hi
Is it available to save recording files as m3u8 format threw oZone?
I'd tried using MovieFileOutput to save it but error came out.
Please let me know any idea to get m3u8 from ozone
Thanks

There are two copies of ozConfigDefines.h in this project:
server/src/ozConfigDefines.h
server/src/base/ozConfigDefines.h

This is confusing. One of them should be deleted. The contents of these files are quite a bit different from one another so I cannot tell which one is "right" simply based on their contents.

Both the cmake and autotools build systems use the one under the base subfolder.

Anyone have any thoughts before I nuke server/src/ozConfigDefines.h ?

I want to know if there is a way to save the original stream when there is an event instead of reencoding it? If I were using a camera directly connected through V4L, then I would want to encode the video for storage. With IP cams, the stream is already in h264 or h265 in most cases and I would want to preserve that.

If there isn't a way to do this currently, would you be open to the addition of the feature? I could work on it once the other PR gets merged.

Fatal should be sparingly used and program exits only when its in a really messed up state. Missing RTSP feeds/timeouts etc are not candidates for program exit.

https://github.com/ozonesecurity/ozonebase/blob/master/server/src/providers/ozNetworkAVInput.cpp#L246-L253

This code loops a video when it reaches EOF. However, the browser needs to be refreshed to see the looped video (frames keep going, but seems the persistent connection with the browser is terminated before the loop starts).

real life situations, mostly in home and in front of door. Purpose - craft a 'people detector' algorithm.

Hi

I wanted to play mp4 on html5 after saving RTSP video files created by MovieFileOutput.

MovieFileOutput recorder("cam", "video", "mp4" ,40, videoParms, audioParms );
recorder.registerProvider(people2);

Because it's encoded to MP4V, however, there is a codec issue to play it on html5.
Is there any solution to record MP4 files with h264?

Ubuntu version is 16.04

Please let me know the details.
Thanks.

The cmake build system has been tested successfully from-source on redhat and ubuntu distros.

Today I moved into a (rpm) package building environment and got the unexpected linker error:
../libgen/libgen.so: undefined reference to gConfig'`

This only occurs when attempting to build via the rpmbuild tool.

That is when I remembered the original autotools build system built static, instead of share libraries. Sure enough, changing the cmake files to build Static libraries allowed rpmbuild to successfully a package.

This issue is to remind myself to do two things:

• Learn from @web2wire why we are using static libraries, and whether or not we plan to ever go with shared. I'm sure there is a reason, I'm just looking to understand what it is.
• add the STATIC parameter to each add_library command. I'd like to get #29 merged before I do this to avoid a merge conflict.

Ideally, to create a server implementation, a single header include and a single library include will be a very low barrier to entry for a 3rd party person wanting to get a quick start. He should be able to copy a lib and a header to his own dir and write a simple_example with just g++ example.cpp -lozoneserver -I. or something

It is useful for application developers to know when a particular class has completed a transaction it was meant to do.
Example, my app may want to know when EventRecorder has finished completing an event recording to update my DB, or when MovieFileOutput writes a video.

Is this repo actively developing or a dead project?

a) fills in dummy frames when there is no provider (at any time)
b) Be able to generate some form of notification to the app when its being used (app will use this to detect the case when there is no camera feed)
c) Ensure downstream processors don't analyze when we have dummy frames

Related to #45

Notification Triggers

Camera

- When not reachable 
    - When reachable but no feed
- When blank screen/blue screens are being shown (maybe keep a counter of same frames and report if all of them are uniform color) -not sure if SignalChecker does this? Not sure if this is the same as "reachable but no feed"

Motion Dectector

- When motion is detected

Event Recorder

- When a "new event" recording is started
- When a "new event" recording is completed

Movie Output

- When a "new movie" recording is started
- When a "new movie" recording is stopped

Lets see what happens

Hi
I tried saving movie files recoded from ip camera.
But it does not create actual mp4 files while in running ozone.

MovieFileOutput recorder( "recorder" , "/tmp", "mp4", 20, videoParms, audioParms);

I think bc it does not passing progress stage while recording.
Is there any idea to solve this issue to create a recorded file?

zmConfgen, zmDB and stuff like that should be taken out (plus all namespaces to be oz #5 )

Goal is:

1. Connect to nvrcli using some mech (simplest is nvrcli listens on a thread for commands)
2. Angular front end
3. NodeJS ONVIF plugin for discovering cameras
4. One page for montage

so our example code can look like:

oz::Application app

and so forth, for all public APIs

output:
git submodule update --init --recursive Submodule path 'externals/dlib': checked out '97151133b07c434c16222a2e11ec735ab19e2540' Submodule path 'externals/ffmpeg': checked out 'da4ea971617351600f49437bc9d489e650b4de38' Submodule path 'externals/json': checked out '0f04e42dd5ee53af466e25a82667fe4c3b039775' Submodule path 'externals/openh264': checked out '9e75838c8638c48a32b15c73c9da7b1fe942fd5f'

when I look up the commit for dlib, it is dated before the current master. I am unable to determine how it is choosing what version to check out.

The build system is inherited from ZM V1 and has tools and headers that aren't really relevant to V2. Should be tidied and updated.
