Lag when left in Full Screen Montage

[steveearle86]

Before you create an issue, please make sure you have read the FAQ at https://github.com/pliablepixels/zmNinja/wiki/FAQ. Common questions on API, no image etc are covered there.

Platform & OS Version
Android (Not sure which version)

The version of the app you are reporting:
v1.2.41

Device details:
Android Fire Tablet

What is the nature of your issue
Bug?

Details
Open the app,
go to montage,
set full screen,
leave for some time (not sure exactly how long, perhaps hours rather than days) and the whole app is laggy (pressing the up arrow in the pink circle in the bottom right is so slow, the video image is laggy).
I have this device running zmNinja 24/7 for constant surveillance. I have to close the app by bringing up the app list and swiping it and then reload the app.

Thanks. Questions:

1. Do you see a memory build up in the app?
2. Do you see extra zms processes being spawned in zoneminder over time ?
3. Is this only in montage? What happens if you keep live view of one monitor for a few hours?

Hi. How would I find the answers to 1 and 2 below? On 19 Jul 2017 12:56 am, "Pliable Pixels" <notifications@github.com> wrote: Thanks. Questions: 1.

I have now installed the debug app and have been running it for a few hours.

I kept getting the following messages in the log

2017-07-20 22:44:57.953816 | web_php |   | 2345 | ERR | socket_sendto( /var/run/zm/zms-310687s.sock ) failed: No such file or directory | /usr/share/zoneminder/www/includes/functions.php | 1993

for 2 hours 30 mins constantly (3630 entries in the database log table)

This continued after a zoneminder restart and also a system restart but stopped when I closed the app.
So far, since I have re opened the app, there have been no more of these messages

Another thing I noticed is that the app had been open for maybe 2 hours and the montage screen froze (i had to close the full screen view and reopen the montage again to get it to restart)

Not sure if any of this is related to the issue?

Now that you have hopefully been testing the app a bit more, is the issue still the same?

[steveearle86]

Seems better at the moment but will try a bit longer. Is this a newer version of the app that isn't released yet?

Just checked and it seems to have slowed down again. The up arrow button isn't responding and the view is slow and laggy

I've been checking on and off all week (since Saturday) and some times I check and its fine, other times its lagging. I haven't restarted the app. Maybe the app clears memory over time?

Thanks for continuing to post your observations. Here is what I think is happening and if that is correct, I don't know how to fix it at the moment, and yes, its possible memory is being flushed automatically.

zmNinja displays the live feeds using and <img src> tag - this is a common HTML tag used to display any image. The difference is that the url pointed to by <img src> happens to be a 'snapshot view' of live monitors rendered by Zoneminder's zms process. What that really means is every 2 seconds the DOM (html tree that represents that page) gets a new image, one for each monitor the montage shows. Now its possible the view is "caching" images and throws them away after a while - that is controlled by the browser (zmNinja uses a chrome web view) and not my app and I don't have any control on releasing that cache (I'll investigate, but I believe this is correct)

[steveearle86]

Just to let you know, I have had the app open since I last commented and the lag has become 7 seconds IE the screen refreshes every second seconds. I can tell from the zoneminder time stamp at the top of the image

[steveearle86]

As a work around is there any way I can restart the app on a schedule and open it in the full montage view?
