How can I change the default system password?

BRIDGE LIVE installation runs on CentOS 7, and you can use standard system
commands. If you need to change the password for user "myuser" then use the
command:
sudo passwd myuser
in the system terminal. You can access the terminal window with the keyboard
shortcut Ctrl + Alt + F1 while browsing the BRIDGE LIVE UI.
How can I change the admin password?

"Password Administration" on page 100
We have a script ready that can change the admin password. Switch to the system
console environment (described above) and navigate to /opt/transcoder/ where
there is a script set_ui_password.sh that will accomplish the task. Run the script
with sudo permissions.
The UI shows that streams are working but I cannot receive
any data on the output.
It is highly probable that there is an issue on the network and the data are being
lost in transmission. Please verify that the network route is accessible between
devices (source, BRIDGE LIVE, receiver) including firewall settings, which may be
configured to block BRIDGE LIVE-related traffic (e.g., ports). You can use Wireshark
to verify whether your target machine is receiving network data, or VLC to
visualize the content.
I see frame drops in the UI. What can be the cause?
There are two possible causes – flaws in the input, or performance bottlenecks.
The rule of thumb is to investigate whether drops occur when the machine is not
fully utilized. If so, the problem may be in the input itself when some frames can
be corrupted by losses during network transmission or compatibility issues.
The other case is that high workload is responsible for frame drops; for example,
high utilization of HW resources (CPU, GPU, NI). Try to lower the performance
drain by stopping some streams and observe the situation further.
Another possibility is to configure the Pipeline to have higher Total bit rate
overhead over Video bit rate. Sometimes, the video bit rate fluctuation is higher,
which causes the video stream to not be able to fit into the overall data limit,
resulting in dropped frames.
What information is needed for troubleshooting by
Support?
In order to provide troubleshooting we need:
• Your description of the issue
• Any error messages you are seeing
• Parameters of input stream(s) – standard compliance, resolution, framerate,
audio channels, the number of configured input streams
• Parameters of output stream(s) – bit rates, resolution, framerate, encoding
option, the number of configured output streams
• Identification of successive devices that receive BRIDGE LIVE’s output stream
