Working with our system and setting up a live demo in Delft revealed several issues previously not encountered.
The first problem, which is something that affects the system as a whole is that Chrome is currently having problems handling more than one video stream. The resulting effect is that the video views swap rapidly between the two video streams. It does not happen every time, but often enough for it to be a problem. In our case, the camera view swaps between showing the desktop view and the face view. Google has been working with this issue from the start, but it is not prioritized. To get around this problem we decided to use two computers per workstation. This worked well and allowed us to have a successful demonstration and workshop. A one-computer solution is not really viable until Google fixes the issue in Chrome.
The other main issue is freezing video streams. This seem to vary between different computers and simply requires that the user exits and reenters the room. Something related to this is that a rather powerful computer is required to run the system with several participants. Test results examining this will be presented in the report. The first set of computers we received in Delft turned out to be too weak to handle rendering of several video streams.
These issues are something that we have to accept when using technology that is currently in development.
