MediaFilterProperties

object

firstQuality

• object FirstQuality Optional
  This parameter defines the initial quality level when playback starts. This is the first bitrate in the ladder.
  If a value is set that does not match the ladder, the closest value will be used. Setting a high value
  may increase the time it takes to start playback, but ensures that initial video quality is high.

bitrate

• integer Required
  Denotes the target video bitrate to be used when starting playback of an HLS manifest.
  The video representation with the bitrate closest to the defined bitrate will be presented first among the available representations in the HLS manifest.

presentationTimeRange

• object PresentationTimeRange Optional
  This parameter is used to cut an asset into a smaller asset by specifying a start and end time.

Properties:

• endTime

  • string Optional
  • format: date-time
    For live content only (including live events that have finished). Indicates the end of the presentation window, like endTimestamp but as an explicit UTC time.

• endTimestamp

  • integer Optional
  • >=0
    For both VOD and live content. Indicates the end of the presentation window, in units of timescale. Given a timescale of "1", a value of "N" set here will constrain the
    video manifest to contain exactly "N" seconds of content. This value is relative to the actual start of the content, not the startTimestamp.

Examples:

• timescale=1, startTimestamp=0, endTimestamp=10: The first 10 seconds of content will be included in the output.

• timescale=1, startTimestamp=10, endTimestamp=70: The 60 seconds of content starting at 10 seconds will be included in the output.

• timescale=10000000, startTimestamp=0, endTimestamp=100000000: The first 10 seconds of content will be included in the output.

• forceEndTimestamp

  • boolean Optional
    A validation parameter.
    When set, requires that the filter endTimestamp be set. This might be useful to limit the duration of a locator associated with a long-running live event, once the live event has ended and the video manifest is closed.

• liveBackoffDuration

  • integer Optional
    For live content only (including live events that have finished). Truncates content from the head of a live video manifest by the specified duration.

• presentationWindowDuration

  • integer Optional
    For live content only (including live events that have finished).
    Indicates the duration of the presentation window, in units of timescale. A presentation window is the depth of content
    present in the live manifest.

• startTime

  • string Optional
  • format: date-time
    For live content only (including live events that have finished). Indicates the start of the presentation window, like startTimestamp but as an explicit UTC time.

• startTimestamp

  • integer Optional
  • >=0
    For both VOD and live content.

• timescale

  • integer Optional
  • 1 to 1000000000
  • Defaults to 10000000
    Defines the unit of time for all the values in this object. The value is expressed in ticks per second.

• tracks

  • list of objects FilterTrackSelection Optional
    Defines the tracks to include in the output. If multiple FilterTrackSelection objects are provided, their configurations will be OR'd together.

• trackSelections

  • list of objects FilterTrackPropertyCondition Required
    Defines the tracks to include in the output. Multiple entries here will be AND'd together.
