metadata Command Examples
Example #1: Creating a Stream with SDI Metadata
[Source ID=1]
Start the SDI metadata encoder instance using the following command:
# metadata 1 start
Create a stream with video, audio and metadata using the following syntax:
# stream create addr=<IPaddr> port=<UDPport> vid=0 aud=0 data=1
Verify the metadata encoder stats:
# metadata 1 get all
The system will return the metadata information:

Example #2: Streaming with UDP Metadata
[Source ID=2]
Create a UDP metadata encoder instance using the following syntax:
metadata create [addr=<IP source>] port=<dest port>
Example:
# metadata create port=8500
The system will return the following message, including the UDP metadata ID:
Metadata source created successfully - ID: 2
Start the UDP metadata encoder (if stopped) using the following syntax:
# metadata <ID> start
Example:
# metadata 2 start
Create a stream with video, audio and metadata using the following syntax:
stream create [addr=<dest IP>] port=<dest port> vid=<id>
aud=<id> data=<id>Example (showing multiple metadata streams):
# stream create addr=10.64.1.124 port=1234 encap=ts-udp videosrc=1 audiosrc=1 datasrc=1,3
Verify the metadata encoder stats using the following syntax:
# metadata <ID> get all
Example:# metadata 2 get all
The system will return the metadata information:
Metadata ID : 2

Example #5: Creating Additional HD-SDI Metadata Sources
To create an additional HD-SDI metadata source and use it in a stream:
# metadata create name="Half the KLV of first input" type=hdsdi # stream create addr=10.65.11.166 port=5678 vid=1 data=3 # stream 1 get |
