Login to BRIDGE LIVE as Transcoder
1. Launch the Terminal app on a Mac or the Command Prompt on a Windows
computer.
2. From the prompt, enter the following UNIX command:
ssh transcoder@device_ip
For example, if the IP address of your BRIDGE LIVE unit is 10.6.0.18, you would
use this command:
You will need to enter the SSH password.
Run the Generate PCAP Command
The command that generates the PCAP file looks like this:
sudo tshark -f "dst port 50010" -i eno1 -w /tmp/input_sample.pcap
-a duration:60
This command as written above will capture every packet with set destination
port 50010 going through the interface (Ethernet card) eno1 for 60 seconds.
When executed successfully, it will create a file on the BRIDGE LIVE device located
at this path:
/tmp/input_sample.pcap
NOTE: Modify the command as needed to reflect your own port number, eno (Ethernet
card), and duration to match your pipeline configuration and requirements.
Download the PCAP File
1. Use sFTP (SSH) to login to BRIDGE LIVE.
2. Navigate to the
/tmp
path and download the
.pcap
file. For example:
get "input_sample.pcap" "F:\input_sample.pcap"
3. If you encounter permission issues, you could try using the following
command:
sudo chown transcoder /tmp/input_sample.pcap
Create a Transport Stream for Inspection
While the steps for doing so are not covered within the scope of this manual,
the next part of the process is to create a transport stream out of the data in the
.pcap
file for inspection.
Probes or Other Tools
Some large organizations may have probes or other various tools that can be
used to verify the streams, and therefore may not need to visually see what the
stream looks like.
