  • Average segment bitrate exceeds the bandwidth (stated in a Master playlist) by 10 times. Average segment bitrate is calculated as the file size (content-length) divided by declared segment duration. Additionally, if the segment size is more than 15 MB, the download of this segment is terminated.

Segment Loss

HlsSequenceNumberDiscontinuity

Event
It triggers if one or several Media playlists (#EXT-X-MEDIA-SEQUENCE discontinuity) along with segments are missing during analysis. For HLS only.
There are several causes of the error:

  • Segment download bitrate is too low that results in skipping download of subsequent playlists;

  • Playlists are not available for downloading (Manifest Download Failure triggers additionally);

  • Issues with content generation at the headend: broken numerical sequence of playlists, restarts or pauses in transcoders/serializers operation. Note, if skipped playlists do not result in segments loss, the error does not trigger.

Static Manifest Error

HlsStaticManifest

State
It triggers when the probe downloads the same playlist during the specified number of attempts. If the probe detects the static playlist which has the same content during two sequent downloads, the download interval will be reduced to the half of the segment duration OR to the half of the TARGETDURATION tag value (the lowest value is selected). The error and reduced download interval will persist until the probe downloads an updated Media playlist. For DASH: only those MPD files can be validated in which Segment List information is specified in the SegmentList or SegmentTimeline element.
Set the number of download attempts in the Attempts of identical playlist downloads field in the Threshold tab.

Manifest Error

HlsManifestError

Event
Depending on an OTT type, it triggers if:
HLS

State
It triggers if a segment has interlaced video stream. Analysis of encrypted segments (decryption keys are not accessible) is unavailable. Enabling of video analysis options in the Add Task form is not required.

OTT Buffer Overflow

HlsSkipSegment

Event
It triggers if system low performance results in OTT buffer overflow with downloaded segments that cannot be timely analyzed by a probe. The system starts skipping segments to avoid RAM overflow.

Bad Segment Duration

HlsBadSegmentDuration

Event
It triggers if declared segment duration exceeds or less than the estimated duration by 10 times. Estimated duration is calculated as the segment size (received in a header of http server response) divided by declared bitrate of variant stream (SegmentSize/DeclaredBitrate).

Zero Duration Segment

HlsSegmentZeroDuration

Event
It triggers if zero duration segment with segment size less than 564 bytes (three TS packets) is detected. If the segment duration is not declared, then the size of each downloaded segment is validated. However, if the downloaded segment size (content-length) is equal to zero, then regardless of its duration the Bad Segment Size event triggers.

Duplicated URI

OttDuplicateRenditionUri

Event
It triggers if some Alternative renditions or Variant Streams have the same URI in a Master Playlist or in a manifest.
For HLS only.

Media Playlist Event

AdInsert_missing

State
It triggers when the probe does not detect the start of an Ad insertion (based on SCTE-35 tags data) during the specified period. The state disappears when the probe detects an Ad insertion start. The trigger is implemented on the basis of the SCTE-35 Advertisement Insertion event.

SCTE-35 Tags Are Not Present in the Playlist

SCTE35Ott_missing

State
It triggers when the probe does not detect SCTE-35 tags in a playlist during the specified period. The trigger is implemented on the basis of the SCTE-35 Tag in OTT Playlist event. For subtitles, you can disable SCTE-35 tags monitoring in Thresholds settings.

Video Buffer Overflow

Video_buffer_overflow

Event
It triggers if system low performance results in buffer overflow and video data cannot be timely analyzed by a probe. The system starts dropping video data before decoding. The data is dropped after TR 101 290 analysis and bitrate calculation, thus, the error does not influence the results of stream integrity analysis. This statement is also applicable to OTT, data drop before decoding does not influence calculation of segments download rate and detection of OTT errors.
The Video Buffer Overflow error occurs only if QoE options are enabled in a task (i.e. video decoder is used).

Task Crash Detected

Resumption

Event
It triggers if a child process analyzing the stream has been restarted by the parent process, because no reply was received within 10s. Parent process monitors the tasks (child processes) performance and in case of critical error restarts the tasks with backward recovery.

It triggers if connection from the probe to server cannot be established within the stated period.

Pcap Loading Error

Pcap_loading_error

State
The Ethernet parameters are measured under the following conditions:
Windows: The Npcap (https://nmap.org/npcap/) packet capture library should be installed on the PC before a probe starts. While installing the library, WinPcap API-compatible Mode and Support Loopback Traffic options should be selected.
Linux: The probe should be launched with root privileges (sudo ./streamMonitor).

Record Access Error

Record_access_error

State
It triggers when the probe cannot access the ‘./record’ folder, its subfolders and content. Usually, the error occurs when the probe was initially started with superuser privileges and then was restarted with regular user permissions. To address the error, stop the probe and change owner/access permissions for the ‘./record’ folder and its content.

5.10.4. Table of Message Identifiers

Information about events, states and alarms may contain the extended data represented as a message ID (see the table below) and returned parameters. This approach allows organizing messages localization.

Message texts may contain macros which should be cut off or replaced. There are two types of macros:

  1. %{PARAMETER_NAME} - a macro with a parameter that should be present with a message. PARAMETER_NAME - a parameter name, a name should contain the following symbols: A-Z, a-z, -, _.

  2. %[OPTIONAL_PARAMETER_NAME: some text with {OPTIONAL_PARAMETER_NAME} inside] - a macro with an optional parameter. It consists of two parts: a parameter name (it meets the same requirements as those for the required parameters) and a text which should be inserted if a parameter is present. If a corresponding parameter is absent, the macro should be cut off. The {OPTIONAL_PARAMETER_NAME} sequence which may be present in a text should be replaced with an optional parameter value.

EXAMPLE:

Macro with a required parameter
"data": {
  "messages": [{
    "id": 502,
    "params": {
      "resolution": "0x0"
    }
  }]
}

Message output result: "Invalid resolution='0x0'"
Macro with an optional parameter
"data": {
  "messages": [{
    "id": 121,
    "params": {
      "descriptor_length": 28
    }
  }]
}

Message output result: "Binary data parsing error: incorrect descriptor_length '28' bytes."
