RPi Cam Web Interface

[RichShumaker]

It is a web page so you would need a way to see the web page.
I do believe that would require a firewall hole punch or putting the page outside the firewall somehow.

I have used a remote desktop on my RasPi in the past to get to get to this.
I am sure there are way better ways to do it as it is a stream and should be able to be 're-directed' or 'repeated' somehow.

[SlowBro]

Yeah, so I think the only way to do this may be an RTMP server. I’m not 100% certain even that would work, I need to experiment.

[RichShumaker]

I built a Pi RTMP server but I did not link it to RPi Cam Web Interface or I would tell you how to do that.
I used vMix and I 'fed' my stream to the RTMP server which distributed it.
I am sure there is an easier way to do this at the MJpeg and Default are both 'streams' just not RTMP.

Is it possible to trigger sound alarm or red blinking of any part of screen in webinterface then motion is detected?

[btidey]

Is it possible to trigger sound alarm or red blinking of any part of screen in webinterface then motion is detected?

When motion is detected then an macro (motion_event.sh in the macros folder) is run if it is present. That, in principle, can do whatever you want.

If the sound alarm is from the RPi Cam server itself then that would be very straightforward as the macro could just trigger a sound event.

If you want the sound or a visible indicator on the remote web client then that is also possible but would need changes on the web interface and the server to support it.

Tried to install onto a new sdcard several times today but get the following error message:

Reading package lists... Done
Building dependency tree
Reading state information... Done
Package dialog is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'dialog' has no installation candidate

I am not sure what this is referring to. As far as I can tell all the files are present in the installation folder.

Any assistance would be appreciated.

[rpdom]

Run apt-get update, then try again. There was a change in the most recent update that changed the location of some of the index files and they need to be updated before you can download new packages.

[rjhazeld]

Thanks for that - did the trick. Frustrating though since the card was new and updated a couple of days ago to make it work on a 3b+.

Hi, I'm trying to use raspimjpeg as a standalone executable and found that it's tightly coupled with schedule.php file, here's what I have done and have observed.

1. Installed RPi Cam Web Interface without any issue and could get all functions up and running in Chrome. Then I tried to use raspimjpeg as a standalone executable.
2. Login with pi user
3. Run sudo su -c 'raspimjpeg' www-data, the output is

Code: Select all

start monitoring for pid: 1991
{2018/04/05 02:31:15} start monitoring for pid: 1991
RaspiMJPEG Version 5.8.10
recommended video buffer size 65536
h264 size set to 131072
recommended video buffers 1
h264 buffers set to recommended 1
Opening FIFO 0 /var/www/html/FIFO 7
Opening FIFO 1 /var/www/html/FIFO11 8
MJPEG streaming, ready to receive commands
send smd 9

4. Opened another terminal and run echo -n "im" > /var/www/html/FIFO, the command executed without any error, but 1) raspimjpeg output didn't change at all and 2) there was no image captured in /var/www/html/media.
5. Run sudo su -c 'php /var/www/html/schedule.php > /dev/null &' www-data, after issuing the command, the raspimjpeg output had two new lines

Code: Select all

Starting command loop
Capturing image

My question is: what did schedule.php do to have raspimjpeg start the command loop (before executing schedule.php, raspimjpeg seemed not starting the command loop) and how should I get rid of schedule.php and still allow raspimjpeg to run correctly?

BTW, raspimjpeg is by far the only solution I can find with such low latency when streaming video to browsers, it's REALLY a great project. Great job folks.

They are a little bit coupled but not tightly.

What you are seeing is that when raspimjpeg starts up its sends a cmd 9 to the scheduler via the FIFO1 which is where the scheduler receives things like motion detect commands. cmd 9 is used to reset the scheduler and allows it to get into sync with its schedule and do things like period change commands etc. If FIFO1 is not set up and active then raspimjpeg stalls as there is no extra detection on that. As soon as you start up the scheduler then FIFO1 becomes active and it proceeds.

You can set up FIFO1 independently of scheduler if you want to get and handle things like motion detects from raspimjpeg. This would allow raspimjpeg to start up OK.

If you are not interested in the motion detect then you can disable raspimjpeg from trying to use FIFO1 altogether by setting motion_pipe in /raspimjpeg to empty.

Code: Select all

motion_pipe

instead of

Code: Select all

motion_pipe /var/www/html/FIFO1

Worked like a charm! Thank you btidey!

Another question: I found on the raspimjpeg github site https://github.com/roberttidey/userland saying that "This branch is 95 commits ahead, 189 commits behind raspberrypi:master. ", as a .NET background developer I don't know if there is any DLL hell situation in C world in this case, meaning that whether raspimjpeg depends on some other components which have been updated in the raspberrypi:master branch, or the compiler just statically linked all dependencies into raspimjpeg executable. Will there be a plan to merge two branches?

The raspimjpeg github uses a fork of the raspberry userland as an environment to compile from and have all the MMAL references etc. The only extra commits we add are in the userland/host_applications/linux/apps/raspicam/ part where the raspimjpeg source is.

We only extract out the raspimjpeg binary so the other applications in here like raspivid are unaffected and will be using the official raspberry userland builds.

I occasionally refresh the core userland code to bring it in line with the official version to benefit from any improvements made there.

Hi..

How to set the video recordings to not exceed 20 seconds with one second between each event?

I entered 20 in Max_Capture without success

Thanks for your help

[btidey]

Hi..

Thanks for your help

What max_capture does is to simulate a motion end signal after this interval if a video recording started by a motion start trigger lasts longer than this. Note this is just the motion end signal. For it to have an effect then there must be something in the scheduler Motion End command set up.

There is a separate control could video split (under camera settings which will automatically break any video recording into separate segments of that number of seconds.

I would like to set up my RPi cam using this and then use it in Home Assistant (a freeware home automation package). Is there a mjpeg stream available to directly connect to without using the html front end?

You can access the mjpeg stream outside of the web interface by using the same url the web interface uses.

Code: Select all

http://ip/html/cam_pic_new.php?pDelay=40000

where html is the folder you installed into. pDelay is optional but controls the frame rate of the stream in microseconds per frame.

1) /dev/shm/ is a temporary folder set up in RAM so there is no SD card wear involved. That is why cam.jpg is written there and links used. Same with status file.

2) That url will work if you are using port 8080, installed direct into /var/www rather than subfolder, and allowed the jpglink in the install. The jpglink determines whether cam.jpg is available as a direct linked file. I prefer to use http://myPi:8080/cam_pic.php which will achieve the same thing

You can obviously create a browser shortcut on your phone to give direct access without going through the browser.

You could make the web side more mobile friendly by changing the style sheet and sizes around somewhat.

If you want to make a full blown app then all the functionality can be achieved via urls so one could create an app user interface and utilise the existing urls to provide the functionality.

I believe there are also some camera shell apps that you an tie this into.

Hello,

due some circumstances (someone has stolen my cam in the garden and looked fully inside the camera this idiot) I had to install a completely new raspberry cam.

I re-ordered the zero w and put the newest stretch image even with the current RPICAM Control last week. I installed the scripts as before (every hour a break also every 20 seconds a photo).

The settings are as the same as on my other cam on the first version of the rpi (running inside my flat). Now I am wondering why I have nearly 100% cpu load with a load average from about > 2. Compared the settings to the old raspberry are the same, so the cpu load should be lower than on the old pi because it runs at 1000 mhz (the old pi at 700). I verified with the commands for reading out the clock speed, the pi zero truely runs on 1000mhz. It records on a mounted nfs source via wifi, the old pi directly via lan. All other settings are the same.

here is htop:
