Stream Statistics

The Encapsulation Protocol type selected for the decoded stream, including:

• TS over UDP
• TS over RTP
• TS over SRT

The current operating status of the stream. Possible values are:

• STOPPED: Stream is currently stopped by the user.
• LISTENING: Stream has been started by the user, but no data is currently being received.
• ACTIVE: Stream is actively flowing into the decoder system.
• UNLICENSED: The stream contains features that are not permitted by the current license set. This can include TS-SRT (although licensing will prevent the creation of SRT streams, so this protection may not trigger).
• RESOLVING: For TS-SRT only, a FQDN host address is currently resolving.
• CONNECTING: For TS-SRT and TS-RTP with FEC only, a connection is in the process of being established.
• FAILED: For TS-SRT and TS-RTP with FEC only, the streaming connection attempt failed.

The number of times the streaming module attempted to connect to the stream.

For example, 2 (Last: 19h57m54sec ago)

A summary of the streams that have been recognized. This includes:

• Video - H.264 or HEVC video streams (possible values are 0 or 1)

• Audio - recognized audio streams (possible values are from 0 to 8)

• KLV - recognized KLV streams (possible values are 0 or 1)

• Filtered - When PID filtering is used, the number of streams that were rejected because of the filter. Video, Audio and KLV could all be filtered and counted here.

MPEG2TS Lost Packets

RTP Lost Packets

Unlicensed Packets

When present, the number of packets that were flagged as UNLICENSED (See “State” description above).

Dropped Packets

When present, the number of packets that were dropped. A packet could be dropped for various reasons, including:

• Corrupted frame

• PID filtering (not supported in 1.0)

• Demuxing error

Dropped Bytes

When present, the number of bytes that were dropped, corresponding to “Dropped Packets”.

Last PID Dropped

When present, the MPEGTS PID number of the last packet that was dropped.

Errors

When present, the number of errors encountered in the streaming module. Also includes when the last one occurred.

Last Error

The most recently encountered error with a brief description.

When present, the number of frames that had missing or bad MPEGTS continuity counters.

Timestamp Rollovers

When present, the number of times the timestamp “rolled over” from a high value to a much lower value.

PES Size Mismatches

When present, the number of times the PES Size Mismatch error occurred.

New Stream Flags

The number of times the decoder’s stream ID was switched without restarting.

Resumed Stream Flags

The number of times a break in the stream was detected. For example, a resumed stream would be detected if the encoder stream were stopped and then started again.

PCR PID

For MPEGTS streaming protocols only, the PID of the Program Clock Reference.

Local Version

Version of the SRT Library implementation on the decoder.

Peer Version

Version of the SRT Library implementation on the remote streamer.

Connections

Number of connection attempts. Severe network congestion may cause the connection to drop and automatically reconnect.

Local Port

Port number being used on the decoder.

Remote Port

Port number being used on the remote streamer.

(AES encryption must be enabled) Indicates whether the decoder can decrypt the stream/State of the decryption. Possible values are:

• Active
• Initializing
• Inactive (no passphrase)
• Inactive (invalid passphrase)

Number of reconnection attempts. Reconnections will automatically occur in the event of severe network congestion.

Indicates the amount of time that has passed (in seconds) since the last rejected SRT stream.

In case of a rejected SRT stream, this statistic will identify a reason for the rejection. Possible reasons include:

• 1:(Error in system calls)
• 2:(Peer rejected connection)
• 3:(Resource allocation failure)
• 4:(Rogue peer or incorrect parameters)
• 5:(Listener's backlog exceeded)
• 6:(Internal Program Error)
• 7:(Socket is being closed)
• 8:(Peer version too old)
• 9:(Rendezvous-mode cookie collision)
• 10:(Incorrect Passphrase)
• 11:(Password required or unexpected)
• 12:(MessageAPI/StreamAPI collision)
• 13:(Congestion controller type collision)
• 14:(Packet Filter settings error)
• 15:(Group settings collision)
• 16:(Connection timeout)
• 17:(Authentication required or unmatched)
• 1402:(Already connected)
• 1404:(PublishingID required or unmatched)
• 1406:(PublishingID unexpected)
• 1500:(Internal server error)

Skipped Packets

The number of SRT packets that were ultimately dropped. These are packets that have arrived at the destination device too late, or that never arrive at all. The time to play the packet has arrived and the lost packet was not recovered, so the decoder/receiver will continue playing. Some type of video artifact may result (i.e., a replayed frame or video blocking artifacts).

Recovered Packets (SRT)

The number of Lost SRT packets that were ultimately recovered. No streaming errors would be detected in the playback because they were recovered in time.

Skipped Bytes

The number of bytes corresponding to “Skipped Packets”.

Local Buffer Level

SRT decoder buffers are the received stream packets waiting to be decoded. This statistic shows the portion of the decoder buffers up to the first missing packet. In other words, the remaining time to transmit the missing packet before it’s too late. The level of the decoder buffer in absence of packet lost is just below the latency value. In presence of packets lost, it is between 0 and the latency value.

Maximum of the decoder and encoder configured Latency. For example:

• Encoder Configured SRT Latency = 750 ms
• Decoder Configured SRT Latency = 20 ms

The SRT Stats Latency (which is the current SRT connection applied Buffering Latency) = 750 (largest of the two).

At startup, handshake exchanges the value configured on both sides, and the largest one is selected.

Compression

The name of the compression standard used for the media.

• For video, it could be H.264 or H.265.
• For audio, it could be AAC-ADTS, AAC-LATM, MP1, MP2 or MP3.
• For KLV, it will be UNCOMPRESSED.

Bit Rate

The measured average bit rate of the elementary stream.

Program ID

In the MPEG2 Transport Stream, this is the Program ID (PID) of that elementary stream.

Received Packets

The number of packets received for this elementary stream.

Received Bytes

The number of bytes received for this elementary stream.

PTS

The most recently encountered Presentation Time Stamp in this elementary stream.

DTS

The most recently encountered Decode Time Stamp in this elementary stream.
