AWS::MediaLive::Channel VideoBlackFailoverSettings

MediaLive will perform a failover if content is considered black for the specified period.

The parent of this entity is FailoverConditionSettings.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:

JSON

{ "BlackDetectThreshold" : Double, "VideoBlackThresholdMsec" : Integer }

Properties

BlackDetectThreshold

A value used in calculating the threshold below which MediaLive considers a pixel to be 'black'. For the input to be considered black, every pixel in a frame must be below this threshold. The threshold is calculated as a percentage (expressed as a decimal) of white. Therefore .1 means 10% white (or 90% black). Note how the formula works for any color depth. For example, if you set this field to 0.1 in 10-bit color depth: (1023*0.1=102.3), which means a pixel value of 102 or less is 'black'. If you set this field to .1 in an 8-bit color depth: (255*0.1=25.5), which means a pixel value of 25 or less is 'black'. The range is 0.0 to 1.0, with any number of decimal places.
