[basicUI]: ipcamera videostream in basicUI sitemap throws exception #745

Boby71 · 2021-01-02T11:56:30Z

The problem

When going to a page within the basicUI sitemap containing the video element the following exceptions are being thrown:

HTTP ERROR 500

Expected behavior

I expected the video stream to be shown on the page.

Steps to reproduce

Define an item which contains the URL to a video stream of an IPCamera. For me it's the provided channel of the IPCamera binding:
Create a page "sitemap" with the following content:

sitemap page_328b2c7c3a label="New Sitemap" {
    Video item=DoorCam_MJPEGURL
}

Open the sitemap in the browser -> exception

Additional information

My IPCam is an INSTAR 9008 Full HD; the provided URL of the item can be opened an viewed at in any browser without any problem. This case was already mentioned here, but as I don't have the rights to move the issue to another repo, I reopened the case here: openhab/openhab-addons#9518

The text was updated successfully, but these errors were encountered:

lolodomo · 2021-01-02T12:19:24Z

Is it working with a sitemap created manually in a .sitemap file (not with MainUI) ?

lolodomo · 2021-01-02T12:45:44Z

A video widget requires a mandatory url argument, something like:
Video url="http://xxxxxxx.mp4" item=VideoUrl

https://www.openhab.org/docs/configuration/sitemaps.html#element-type-video

Issue to be closed (wrong sitemap syntax) or to be associated to MainUI rather than BasicUI if the problem is the sitezmap builder from MainUI.

Boby71 · 2021-01-02T18:20:09Z

Unfortunately, it's the same when I add the URL to the element:

Sitemap:
Video icon="camera" item=DoorCam_MJPEGURL url="http://192.168.1.50:8081/ipcamera.mjpeg"

When I put the video element into a .sitemap file and open the page, there is no exception:

.sitemap-file:

sitemap test123 label="Test123" {
        Video icon="camera" item=DoorCam_MJPEGURL url="http://192.168.1.50:8081/ipcamera.mjpeg"
}

I still don't see an image in the video control, but this might have other reasons I need to check.
But the exception is ONLY thrown for the sitemap built by the sitemap builder in GUI.

The used URL works fine:

But the exception is ONLY thrown for the sitemap built by the sitemap builder in GUI.

Ok, so this is not a Basic UI bug but rather a bug in the MainUI sitemap builder.
@ghys : any idea ?

Skinah · 2021-01-03T03:17:37Z

This works for me if contained in a sitemap FILE and viewed in basicUI and the ios app. Note the encoding is added.

Video url="http://192.168.1.xx:54321/ipcamera.mjpeg" encoding="mjpeg"

I have heard others say it does not work if stored in the JSON database and that putting it into a file fixes it, but I have not tried it myself to confirm. I am now mostly using a OH3 widget to display the feeds as it is much better as it has the ability to overlay controls and alarms on top of the feed.

Boby71 · 2021-01-03T10:05:52Z

Encoding doesn't make a difference - it even fails when it's used too. But even if this had been the reason:
From a users perspective at least a understandable error message should show up in the log, like "no encoding used - skipped the element" or something like that. Throwing an exception and freezing the system isn't the way.

To sum it up:

video element on MainUI created sitemaps causes exceptions
(the same) video element in a .sitemap file doesn't throw an exception

Also catch remaining exceptions and log a warning/ignore the parameter instead of making the whole sitemap building process fail. Fix wrong feature ID for the video widget URL. Fixes openhab#2047.

Should be fixed by openhab/openhab-core#2072.

Stupid question: How can I find out which PR is included in which build/snapshot?
I had a look at the Jenkins build log, but there were no changes in #2116?
https://ci.openhab.org/job/openHAB3-Distribution/2116/

ghys · 2021-01-05T19:45:33Z

@ghys: I guess this will solve this issue as well?

Yes, thanks.

How can I find out which PR is included in which build/snapshot?

Look at https://ci.openhab.org/job/openHAB-Core/changes and check that your distribution build was made after the build which included the commit you're after. openhab/openhab-core#2072 is not yet merged btw.

Boby71 · 2021-01-05T20:09:02Z

@ghys , thank you!

I did a quick check and used exactly the same sitemap in a .sitemap file and in a UI generated sitemap:

sitemap test label="Test" {
    Text icon="camera" item=DoorCam_MJPEGURL label="Video-URL"
    Video icon="camera" item=DoorCam_MJPEGURL url="http://192.168.1.50:8081/ipcamera.mjpeg" encoding="mjpeg"
    Text icon="camera" item=DoorCam_ImageURL label="Image-URL"
    Image icon="camera" item=DoorCam_ImageURL url="http://192.168.1.50:8081/ipcamera.jpg" label="Image" refresh=60
}

I don't get an exception anymore, but a completely different behaviour in basicUI, depending on where I created the sitemap:
.sitemap file:

UI made sitemap:

Do you think this different behaviour will be fixed as well? Thank you!

Doing the same in a .sitemap file there's no problem at all.

Hi, is it solved? I still get this issue after installing version 3.1.0 Build #2147.

Hi, is it solved? I still get this issue after installing version 3.1.0 Build #2147.

it works for me. Do you a) use the item provided by the channel and b) the video URL in parallel?

vcatini · 2021-01-24T04:45:47Z

Yes, I use both, and I get error message in the screenshot. It works fine in a text format saved sitemap file. I updated openhab to the latest snapshot through openhabian config console. What else I miss? I'd like to remove sitemap file to manage it in the UI but I can't. Many thanks for any help.

I use the URL and port provided by the thing - and not the address of the cam itself. My cam is 192.168.1.82, but I use 192.168.1.50:8081 (the port needs to be defined at the thing).

Hi, I tried also using image widget instead of video but even if I get no error in the log I also get no image in the UI.
I use same configuration as Boby71 one, this is the code in the sitemap UI:

sitemap page_a3a0449c28 label="New Sitemap" {
Image icon="camera" url="http://192.168.1.57:54321/ipcamera.jpg" label="Cucina" item=CameraCucina192168185_ImageURL refresh=1000
}

where IP address is the openhab one and port is the one configured at things level. If I put the URL directly in the browser it works fine, if I put this sitemap code in a sitemap file it works fine.
I just look at web page source code to search for differences:

the one created by the UI reports the following line for the image:
the one created by the sitemap text file reports the following line instead:
that's clear why there is no image in the first case but I don't know which is the main cause.
I have the following version of openhab installed: openHAB 3.1.0 Build Javascript error when actionAnalyzerItems value is a string #2158
I have followed all the steps in this thread, I think.
Many thanks for all your support

I just look at web page source code to search for differences:

the one created by the UI reports the following line for the image: img src="images/none.png"
the one created by the sitemap text file reports the following line instead: img src="../proxy?sitemap=prova.sitemap&widgetId=00&t=1611574750279"
that's clear why there is no image in the first case but I don't know which is the main cause.

The missing image is related to another bug I filed an issue for:
