SOLVED Display .JPG image on sitemap

1

Hello,
I have been trying to get this going for days now and am going round and round in circles. What I am trying to do is display a .JPG file from my Raspberry pi3 root folder on my sitemap.
Heres my sitmap bit-:

Frame label=""
        Text label="CCTV" icon="" {
            
            Image url="http://192.168.1.119:8080/img.jpg" refresh=60000
        }

and here is the image showing on the Pi3

Looking for a place to get started? Check out 'sudo openhabian-config' and the
documentation at https://www.openhab.org/docs/installation/openhabian.html
The openHAB dashboard can be reached at http://openHABianPi:8080
To interact with openHAB on the command line, execute: 'openhab-cli --help'

[20:12:10] openhabian@openHABianPi:~$ dir
img.jpg  README.txt  x264
[20:13:15] openhabian@openHABianPi:~$

I am not a linux pro and am struggling with this now. Can anyone point me in the right direction?

That would require whatever is serving the HTTP to map incoming requests to your root folder. That’d be unwise.

Simplest thing is to put your jpeg in the openhab folder meant for sharing web content - there’s a /html folder under your user configuration, alongside /transforms etc.

@crumpy10, when you follow rossko57’s advice, make sure to use http://192.168.1.119:8080/static/img.jpg (notice the static) as the URL.

Thanks for the advice @rossko57 and @rlkoshak
I can see this folder from my windows share, can I just place the image file in there through windows?

Then all I will have to figure out is how to save the image every so often from ffmpeg into the folder on the raspberry pi.

5

For the first part, I’m guessing there is a permission problem with Samba preventing you from writing to the files. Search the forum, there is lots of help for that problem posted.

You can maybe use Grafana Image Charts for an overall approach to periodically getting the image.

Hi Rich,
Thanks for the info, I actually just remotely changed my setup and it works as suggested by putting the img file in the html folder directly on windows.

just the FFMpeg bit to work out now…later when I get home…

Not sure if I have enough processing power for Grafana on a Pi3 ?

7

Have you seen the ipcamera binding? It may make things easier for you even if this is not a camera as it will fetch jpgs and also serve them with benefits over the method you are using now like being able to cast the picture to Chromecasts and creating animated Gifs…

You also do not mention what you are viewing the sitemaps on? android or apple products?

image = works great on Android, but bad on ios app.
webview = works great on ios app, not so great on Android.

streaming video:
HLS = works great on ios, not on Android app.
mjpeg = works great on Android, not on IOS app.

@matt1 Yes I have seen your binding but maybe wrongly assumed that it only streamed video feeds and I am wanting to keep the CPU usage on the Pi3 down as much as possible.
I have a Hikvision NVR standalone with a single camera at the moment (will be increasing with upto 8) and was just looking at viewing snapshots on IOS and Android devices. In the future I would like to display on a touchscreen Dell monitor running Habpanel.
Is it possible to setup your binding to just send snapshots every say 5 - 10 seconds?
Cheers
Simon

Yes in fact up until 4 months ago it could only do snapshots.

For the lowest cpu load disable sending the snapshot to the image channel. Whatever the openhab framework it doubles the cpu load and you can use the bindings file server to deliver the snapshots as you are doing now.

Btw the binding only places a load when you view the video streams, so if you rarely watch the feed it will rarely use cpu and you will be surprised at how little you need.

10

OK I might have to take a look at that later then when I get home.

The only thing is, the NVR is a Chinese clone that I can only get RTSP streams from. Will that work with the binding ok?

Sorry I am a newbe at all this, especially Linux.

11

If you can not get a snapshot then the binding is useless as it requires this for the camera to come online in openhab. If it is a Chinese clone with counterfeit firmware then look for the ability to expose the cameras on separate ports in the nvr settings. If it is a complete fake then your out of luck.

Ffmpeg will do it as I use it in my binding to create snapshots from RTSP streams when creating the animated gif files. This will be higher cpu and other resources like network traffic because you have to stream to get the snapshot.

@matt1 Yep its one of those, I dont think there is any other way of exposing the cameras.

Anyway, I sort of have the snapshot thing working but am getting a lot of errors like these-:

Sometimes it picks up a good snapshot, sometimes not. Any idea what the errors are all about? Sorry I am a total learner at Linux and FFMpeg.

try adding this to the command BEFORE the -i

-rtsp_transport tcp

Google differences between UDP and TCP if that works and you wish to know more.

14

Thanks that works much better now, will have a look and get to know the differences. Just struggling to understand the FFMpeg syntax at the moment. What each part of the command does etc…
