IpCamera binding - Breaking changes and new features in 3.2 Milestone 3 and newer

matt1 · October 21, 2021, 2:16am

Good to hear its working and always interesting to see graphs that show things have changed, either in the positive or negative direction. The newer changes not yet merged should further reduce system loads for cameras that use digest auths weather it is enough to be seen on graphs I don’t know. The other big change is that for people that leave streams open on tablets 24-7 the binding is getting some TLC to ensure the camera can go offline for unlimited time and it should still having a working picture on the tablet when the camera comes back online. A lot is changing in the binding at the moment so any help with testing and giving feedback is apricated.

I installed the updated binding, but noticed some strange things:
I can now see again the ipcamer.mjpeg stream in my sitemap view. The weird thing is that if I am not viewing the sitemap, either on my PC or my android app, then I can’t view the ipcamera.mjpeg stream in my browser by using a direct URL. If I open the app on my phone then I can see it in my browser. The snapshots.mjpeg is not affected by this.

What is the name of the zip file you downloaded or is it in milestone 3? I made some changes that may help in the downloadable jar found in first post.

PeterB · October 24, 2021, 11:48am

I uninstalled the binding of M3 and downloaded the zip dated 2021-10-20.

Try downloading it again as I made some changes to ipcamera.mjpeg the last few days. The date is the 24th now and those changes got merged and will be in the next milestone so if there is an issue it would be great to know ahead of time so if you can test that would be great. Thanks.

I tried the new version, but no change. If I open the ipcamera.mjpeg stream in my browser I don’t see anything. If I open a new tab, I get the video on this tab. The other tab still doesn’t show the video.
If I refresh the first tab then it also shows the video. I tried it on both chrome and edge, the exact same behavior. For me this is not a real issue since the openhab interface shows it correctly, but it is very strange.

What does the log show in trace mode?

Hi Matt,

Please check the log below. First I opened one browser tab and somewhat later the second tab timestamp 08:19:35.769. Just to remind you, I am running openhab on Windows 10, I don’t know if it can have something to do with it.

I can reproduce this here and have a work around for you to try. Setup the camera to use ‘basic/digest’ instead of ‘digest’ only.

Three boxes need changing in two different areas…

NETWORK>ADVANCED SETTINGS>

and

SYSTEM>SECURITY>AUTHENTICATION>

When you change from digest to using basic auth you MUST pause and then unpause the camera/s to force a reconnect, it wont work till that is done.

I can not reproduce it on any other camera except Hikvision and only when digest is on.

PeterB · October 26, 2021, 8:23am

I changed these settings for both web and rtsp. I can confirm that it is working now. I get a message about a possible security issue when changing to digest/basic, but I don’t think this is really an issue since the camera is not accessible from the outside.
Thanks for your support and time you spend on this binding (and the ESP Milight binding)

matt1 · October 26, 2021, 9:30am

I just uploaded a newer jar with a fix in it so digest will work in the newer build. Digest is more secure if someone is on your local network, basic can be reversed in 1 second by an 8 year old kid. If you don’t believe someone can get into your network, what stops someone talking a wired external IP camera off your house and plugging their laptop into that cable that was connected to your camera.

Thanks for reporting the issue and testing it.

PeterB · October 26, 2021, 4:14pm

thanks, just tested it and it’s working perfectly!
