You should only need to update 2 files (the I_ and the L_ files) which are 3 days old on GitHub? The url and username/password variables should all be autocreated upon luup reload.

[RHCPNG]

I can't get it to work, the variables don't show up. I have even removed all files from openluup and started over, but same result every time. Any ideas?

[rafale77]

Ok, I think I have now a pretty good idea of what happened. It would be helpful if you could look at your logs to find out what the error is though.
The issue seems to be that my installation of openLuup is not quite "vanilla" as I have made a few minor modifications to it and am also running it on LuaJIT along with some additional libraries instead of the standard Lua5.1 interpreter. I will make a minor edit to try to fix it.
Please try it and report back with what error you see in the logs if any.

You can look into the openLuup section of the forum to see what changes I made to my openLuup installation. I basically decreased the CPU load by >75%

https://smarthome.community/topic/151/rapidjson-instead-of-cjson-and-dkjson
https://smarthome.community/topic/179/luajit

Only change is to the L_Amcrest.lua file so you can just replace that file in your installation and reload.

@rafale77 said in Amcrest/Dahua Camera Plugin streaming and PTZ for openLuup/ALTUI:

I basically decreased the CPU load by >75%

...although, it has to be said, from a pretty small starting level anyway?

[rafale77]

@akbooer

Yes, indeed:
My setup with all the plugins and bridges was hovering around 6-8% CPU load with spikes to 14-18% when I opened an ALTUI page.
Now I hover between 1.5-2.5% with spikes to 4-4.5% with ALTUI opened.

[RHCPNG]

@rafale77 Thanks, I will test it tomorrow.

[rafale77]

Released version 0.3 in the App store.
I realized much simplification was possible with the newer versions of openLuup and that digest actually works with luajit.

[RHCPNG]

Ok, we are a step further. All variables are there now. Firstly, there is a small error in the DirectStreamingURL though. The brackets should not be there.

I have removed them, but still no image.

This is the only thing I get in the log:

BTW I have tried the complete URL in the browser and that works.

[rafale77]

Good news is that the plugin code is executing.
Stating the obvious but, did you check that the ip address and the credentials are setup?
It is working fine here (with the brackets). The display of the stream/snapshot is actually done by ALTUI. depending on the browser you use, it may buffer a bit strangely.

[RHCPNG]

I've put the ip-address in the attributes and the username and password in the variables yes. Maybe add the port? It doesn't need it when I put the URL directly in the browser, so probably not.

[rafale77]

Nope port should not be needed. What version of ALTUI and openLuup are you running?
I am fairly certain now that the plugin I published works since it is working for me. Have to look at other things...

[RHCPNG]

AltUI v2.50.2549. Openluup v20.5.22. It's annoying that the logging does not give anything useful.

[rafale77]

Could you provide a screenshot of your attribute screen as well as a list of all your variables? I really have no idea why it isn't working for you. I even just added a camera to my openLuup setup and had no problem so something else is different. Are you seeing the camera control screen? Can you send commands to the camera like pan and tilt? What browser are you using? Can you try a different browser?

[RHCPNG]

Ok, youre right, the plugin seems to work. I have tested with an other Amcrest model and that one does work. So the problem lies in the older models I have, that's a pity. I will have to do it through zoneminder then.

The PTZ does not seem to work however for my model.

I'm getting this error:

Unknown control type:js_button. See Debug

[rafale77]

I'd be happy to improve the plugin to support more cameras if I can.
If the url is correct and the video is not working it is likely because the codec is not supported by the browser. If you tell me what camera it is, I will take a look.

The error you are seeing about the button is not normal. I will take a look as well. This command is in javascript and is done by ALTUI. I don't believe it is in the plugin code but will check.

[RHCPNG]

I don't get it. When I put the full URL directly in the browser window, like this, I get a stream (outside AltUI).

http://admin:<password>@192.168.1.17/cgi-bin/mjpg/video.cgi?channel=1&subtype=1

So that would mean it isn't the codec, right?

The model is: Amcrest IP3M-943B

[rafale77]

Not sure why they would not work. It uses the same H264 and mjpg codec but your url uses mjpg. I have a bunch of IP3M-956/954 and they all work fine too.
Good catch on the js_button. I never noticed it but it seems to be inherited from deprecated code. I will fix that. Only some buttons were affected.

I took advantage to fix a few thing around pan tilt/scanning. Released version 0.4.
This plugin was very raw when I took it over... I am finding so many things which were not quite right.

[RHCPNG]

There are some annoying issues with my model. I can't even manage my camera's through Chrome or Firefox, only through IE.

Will try your new version soon.

[RHCPNG]

I have tested the new version with my working model, but the buttons still do nothing. The error is gone and I don't see anything strange in the log.

The working model is the Amcrest IP4M-1051

[rafale77]

I am not getting any of the WGET errors in my logs. I am not sure what this status -1 means besides the fact that the camera is rejecting the call. I am also a bit surprised that your credentials in the url are only partially encoded. (the username is doesn't appear to be). Something doesn't seem right.

Honestly I have not gotten to the bottom of the stream. One of my cameras which I just added has all the pan and tilt buttons work so it is communicated properly but the video does not show. I tested on firefox and none of the cameras show any images.
Will try to dig deeper into this as I think it is more java code from ALTUI than it is a plugin/openLuup problem.
