Hi all, I have a small Lan hosted web-page which displays preview images from various webcams I have. The problem is I can't seem to get a still from my Hikvision DS-2CD2432 camera.

The accepted url for getting a stream or image seems to be http://user:pass@[ip.address]/streaming/channels/101/picture

However the user:pass@ bit seems to have been quietly dropped from chrome.

Is there any other way I can do this?

thanks

You're wanting stream or image from cam not via NVR correct? Does the "101" imply channel 1 from NVR, stream 01 (main)?

If so try just "1" like this: http://user:pass@[camip.address]/streaming/channels/1/picture

Add http port after cam ip if not 80 like this: http://user:pass@[camip.address]:http-port/streaming/channels/1/picture

changing to channel 1 makes no difference :(

I figured the chrome thing by looking at the inbuilt inspection/console, which flagged up a warning:

Code: 
[Deprecation] Subresource requests whose URLs contain embedded credentials (e.g. `https://user:pass@host/`) are blocked. See https://www.chromestatus.com/feature/5669008342777856 for more details.

what is odd, is if I change the url of the image to not include the user:pass bit, I get a broken link, with the console suggesting authentication is a problem (error 401 i think), then click the image, which is a link to a full screen mjpeg stream with the following url:

Code: 
http://user:pass@[ip.address]/Streaming/Channels/1/preview

the link works fine, and if I go back, the preview image then works, as if that chrome instance has then been authenticated. Thus I'm sure it's an authentication problem, and chrome is maybe being contrary about it.

For further clarity/context/confusion, here is the actual html, which shows a broken image until you click on the link and then go back:

Code: 
<A href ="http://user:pass@192.168.1.203/Streaming/Channels/1/preview"><img src="http://192.168.1.203/Streaming/Channels/1/picture" width="420" height="237"></A>

Sorry, I wasn't paying attention to the fact that you're using this in html. That may not work.
and to borrow an example from wikipedia,
Code:

@ auth works if you type it into the address bar, but I don't think it works on hrefs
