metadata Command Examples

Example #1: Creating a Stream with Serial Metadata

[Source ID=0]

  1. Set the baud rate for the serial port to 115,200 using the following command:

    # metadata 0 set baudrate=115200
  2. Start the serial metadata encoder instance:

    # metadata 0 start
  3. Create a stream with video, audio and metadata using the following syntax:

    # stream create addr=<IPaddr> port=<UDPport> vid=0 aud=0 data=0
  4. Verify the metadata encoder stats:

    # metadata 0 get all

    The system will return the metadata information:

    Metadata ID : 0 
    Name : (None)
    Configuration:
    Type : serial
    Format : KLV
    Device : "/dev/tts/0"
    Standard : RS-232
    Baud Rate : 115200
    Statistics:
    State : STOPPED
    Rx Bytes : 0
    Rx OK Messages : 0
    Rx Corrupt Messages : 0

Example #2: Creating a Stream with SDI Metadata

[Source ID=1]

  1. Start the SDI metadata encoder instance using the following command:

    # metadata 1 start
  2. Create a stream with video, audio and metadata using the following syntax:

    # stream create addr=<IPaddr> port=<UDPport> vid=0 aud=0 data=1
  3. Verify the metadata encoder stats:

    # metadata 1 get all

    The system will return the metadata information:

    Metadata ID             : 1
    Name : (None)
    Configuration:
    Type : HD-SDI
    Format : KLV
    Statistics:
    State : STOPPED
    Rx Bytes : 0
    Rx OK Messages : 0
    Rx Corrupt Messages : 0

Example #3: Streaming with UDP Metadata

[Source ID=2]

  1. 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
  2. Start the metadata UDP metadata encoder using the following syntax:

    # metadata <ID> start

    Ex: 

    # metadata 2 start
  3. 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
  4. 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 
    Name : (None)
    Configuration:
    Type : Network
    Format : KLV
    Address : 0.0.0.0 (Any)|
    UDP Port : 8500
    Statistics:
    State : WORKING
    Rx Bytes : 0
    Rx OK Messages : 0
    Rx Corrupt Messages : 0
    Source Address : 0.0.0.0

Example #4: Configuration Information for Multiple Metadata Sources

  1. Get the metadata configuration information for the encoder using the following command:

    # metadata get all

    Returns configuration information for three metadata sources: (1) serial port source configured for CoT (Makito X4 Rugged only), (2) HD-SDI source configured for KLV, and (3) network source configured for KLV:

    Metadata ID              : 0 
    Name : (None)
    Configuration:
    Type : Serial
    Format : CoT
    Status : STOPPED
    Device : "/dev/ttyO0"
    Standard : RS-232
    Baud Rate : 115200
    SPI Sensor Discovery : Off
    SPI UID : (Any)
    Max AirCraft-SPI Delta : 0 ms
    CoT Relaying : Off
    Number Of Relays : 0
    Reclassification : Off
    Classification : UNCLASSIFIED
    Classifying Country : (None)
    Object Country : (None)
    Metadata ID : 1
    Name : "HD-SDI-BNC-1"
    Configuration:
    Type : HD-SDI
    Format : KLV
    Status : STARTED
    Reclassification : Off
    Classification : UNCLASSIFIED
    Classifying Country : (None)
    Object Country : (None)
    Metadata ID : 2
    Name : "KLV/UDP"
    Configuration:
    Type : Network
    Format : KLV
    Status : STARTED
    Address : 10.65.11.169
    UDP Port : 20000
    Reclassification : Off
    Classification : UNCLASSIFIED
    Classifying Country : (None)
    Object Country : (None)

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
input=bnc1 decimation=2
Metadata source created successfully - ID: 3
# stream create addr=10.65.11.166 port=5678 vid=1 data=3 
Stream created successfully - ID: 3
# stream 1 get 
Stream ID : 1
Name : (None)
Configuration:
Address : 10.65.11.166
UDP Port : 5678
Encapsulation: TS-UDP
Contents : Video ("H.264 Video Encoder 1":1),
MetaData ("Half the KLV of first input":3)
