Failed to load stream

[GieltjE]

First of all thanks for this module, it makes life a lot easier.

We are using a custom view with 9 camera's in 24/7 mode, but after a few hours some random camera's go into "Failed to load stream" (the controller says they are online and can display them, so I guess they just hickupped). And they don't return untill we restart the plugin.

Can we help debug this?

• edit- Appears to be a unifi bug, without this addon the same thing happens.

Hi GieltjE,

In our deployment, the whole React app (UniFi Protect) will reload automatically if cameras fail. There is actually a little bug there still, where after such a refresh, the app does not hide the menu bar and sidebar anymore and you are left with a 90% fullscreen instead of the proper fullscreen.

I believe the trigger for failing streams is mainly due to network stability/capacity, but failing camera's should be resolved by above refresh. You might be able to adapt the code a little and add a refresh every hour, for example?

Regards, Remco

An hourly reload was my next option, do you happen to have some sample code for automated reloads?

@Torrentus @GieltjE I am having the same issue, were you able to add a refresh?

[GieltjE]

Just wrote an secondary app that kills it every hour and restarts it.

Something like this should do the trick (don't forget to properly link the event and such).

        private readonly Timer _timer = new Timer();
        private readonly ContextMenu _contextMenu = new ContextMenu();
        private void MainShown(Object sender, EventArgs e)
        {
            Hide();
            Visible = false;
            _notifyIcon.Icon = Icon;
            _notifyIcon.Visible = true;
            _notifyIcon.ContextMenu = _contextMenu;
            _contextMenu.MenuItems.Add(new MenuItem("Exit", (o, args) => { _notifyIcon.Visible = false; Environment.Exit(0); }));

            Tick(null, null);

            _timer.Interval = 10 * 1000;
            _timer.Tick += Tick;
            _timer.Start();
        }

        private DateTime _lastRestart = DateTime.Now;
        private void Tick(Object sender, EventArgs e)
        {
            _timer.Stop();

            Boolean running = false;

            try
            {
                Process[] processes = Process.GetProcesses();
                if (processes.Any(process => String.Equals(process.ProcessName, "chrome", StringComparison.OrdinalIgnoreCase)))
                {
                    running = true;
                }
            }
            catch {}

            if (!running || _lastRestart.AddMinutes(20) <= DateTime.Now)
            {
                if (running)
                {
                    Stop();
                }
                Start();
                _lastRestart = DateTime.Now;
            }

            _timer.Start();
        }

        private static void Stop()
        {
retry:
            Boolean running = false, complete = false;

            try
            {
                Process[] processes = Process.GetProcesses();
                foreach (Process process in processes)
                {
                    if (!String.Equals(process.ProcessName, "chrome", StringComparison.OrdinalIgnoreCase)) continue;
                    running = true;
                    process.Kill();
                }

                complete = true;
            }
            catch {}

            if (running || !complete)
            {
                goto retry;
            }
        }
        private static void Start()
        {
            Process.Start(@"C:\Program Files (x86)\Google\Chrome\Application\chrome_proxy.exe", "--ignore-certificate-errors --profile-directory=Default --app-id=hlfiibnanckjnnlidgdbmbgmobjidoac");
        }

Yes I use goto, sue me or fix it yourself ;)

Not sure how this is going to solve anyones issue as the hole purpose of this app is to run on a Chrome device? and your script seems to reference a windows directory and process...

What language is your script and is it compatible with non-windows based deives?

[GieltjE]

@JoshuaBroad This is C# and used for windows (probably Linux too with some effort) with chrome. Don't know about chrome devices.
