B4J Question Connecting to a CCTV DVR, possible or not?

[Colin Evans]

Hi

I have a sixteen port dvr CCTV device and use a third party android app to view the camera's I just wondered if it would be possible to connect and view using B4J, and if it is are there any examples

WebView1.LoadUrl("http://192.168.1.143:80/") I get the following screen log on

if I tried it in Chrome it states I need the'ie' chome extension, which if I use it works and the submit button is activated and field names displayed, and I can log into the camera views with just the username = admin

I notice from searching the forum a number of people have asked if it is possible but have never had a reply

Did you see this?

[B4X] [class] MJPEG decoder

The attached class is an implementation of a MJPEG over Http decoder. The data is a mix of strings and raw bytes. It is tempting to convert the bytes to a string. However raw bytes do not represent a valid string so you can lose important information during the conversion (which will also slow...

Please state the model and manufacturer of the DVR and I'll see if I can help you.

We already made an APP that connects to a DVR to watch CCTV

Hi

many thanks for your advice, not sure how I could use the examples you mentioned

As far as I can make out the model is H.264 DVR, don't know if that helps but hopefully it does

Thanks again

Very similar, mine just says HD DIGITAL VIDEO RECORDER, and the top sticker is a reference to ICLOUD Software, one touch online, http://www.xmeye.net/

If you know or have the supplier or manufacturer manual, we can configure the DVR agent to access it through a customized client APP.

Hi, thanks again for all your help, I can login using either the browser or the CMS software available on the web

But what I wanted to do is be able to access individual channels (camera1 or camera2 etc) in an app, so I can just display individual camera's without all the bloatware that comes with the browser or cms software.

Not sure if this is possible but thought I'd ask

Thanks again for all your help

Did you try MediaPlayer?

As an alternative - I guess this is bloatware ( although very powerful) but you could try to embed VLC:

I guess that you could also use ffmpeg using jshell.

Hi oparra don't suppose you've got an example of what you achieved so I could have a go with your code, or try to understand better, many thanks

Hi, I have had a look at your suggestion but sadly at a loss as to how to implement it, so thank you but it's a bit beyond my capabilities but thanks anyway
