Low framerates when using web sockets with high res video

Description

In the web service, as the source resolution of a camera grows, the ability to quickly stream frames is reduced. This is particularly noticeable with cameras of 1080p resolution or higher. When this issue occurs, video will start displaying at extremely slow frame rates and, when switching to a larger layout, some video will not load at all.

<br>

Version Introduced

7.1.9

<br>

Platform

Web Service / All

<br>

Steps to reproduce

  1. Connect high resolution (1080p or greater) cameras to a server.
  2. View the cameras on the web service over web sockets.

<br>

Expected result

The cameras stream at roughly the same rate as legacy polling.

<br>

Actual result

The cameras stream at extremely low rates (<1FPS).

<br>

Work Around

Either:

  1. Prefer legacy polling in the web client.
    1. On the gears tab, select “Client”.
    2. Check the “Use Legacy Poll” checkbox.
    3. Refresh the page.
  2. Create lower resolution secondary streams and use those.
    1. Using the client, create a secondary stream with a lower resolution for each camera.
    2. Using the client, create a view containing each of these secondary streams.
    3. In the web client, prefer these secondary streams over the primary.

ESM May Not Connect to Web Service with Self-Signed Certificate

Symptom:

The camera video feed section in ESM displays an SSL error message.

<br>

Problem:

ESM may not connect to the exacqVision Web Service if the web service is using a self-signed certificate. This may be more prevalent on systems where TLS/SSL was configured after being added to ESM.

ESM did not automatically detect the scheme change and requires the user to manually configure the scheme.

<br>

Solution:

Upgrade ESM to version 5.8 or higher.

Unable to Start Web Service on Windows 10

Problem

Users installing the exacqVision web service on Windows 10 machines find that the exacqVision web service is not enabled and encounter errors when attempting to manually start the service.

<br>

Cause

This is due to a port conflict. The default port used by evApache is port 80. This is also the default port for most web services. Windows 10 contains a service which is enabled by default that binds to port 80 before evApache attempts to start and since two services cannot bind to the same port number, evApache and the exacqVision web service fail to start.

<br>

Resolution

There are two possible ways to work around this.

  1. Open Services.msc in Windows and locate the ‘World Wide Web Publishing Service’. Stop this service and change the start up type to ‘Disabled’. You may also consider disabling the IIS service if it is installed on your machine. After these changes have been made you may either reboot your machine or manually start the exacqVision web service.
  2. Manually change the port number to something other than the default of 80. This requires editing a configuration file in Apache. You may find instructions on this in the following knowledge base article: 42205
