#aq_strength ⇒ ::Float

Returns Specify the intensity of the adaptive quantizer (AQ). Must be between 0 and 1, where 0 disables the quantizer and 1 maximizes the quantizer. A higher value equals a lower bitrate but smoother image. The default is 0.

#frame_rate ⇒ ::Float

Returns Required. The target video frame rate in frames per second (FPS). Must be less than or equal to 60. Will default to the input frame rate if larger than the input frame rate. The API will generate an output FPS that is divisible by the input FPS, and smaller or equal to the target FPS. See Calculating frame rate for more information.

#gop_duration ⇒ ::Google::Protobuf::Duration

Returns Select the GOP size based on the specified duration. The default is 2s. Note that gopDuration must be less than or equal to segment_duration, and segment_duration must be divisible by gopDuration. Valid range is [2s, 20s].

All video streams in the same channel must have the same GOP size.

Returns:

  • (::Google::Protobuf::Duration) —

    Select the GOP size based on the specified duration. The default is 2s. Note that gopDuration must be less than or equal to segment_duration, and segment_duration must be divisible by gopDuration. Valid range is [2s, 20s].

    All video streams in the same channel must have the same GOP size.

#gop_frame_count ⇒ ::Integer

Returns Select the GOP size based on the specified frame count. If GOP frame count is set instead of GOP duration, GOP duration will be calculated by gopFrameCount/frameRate. The calculated GOP duration must satisfy the limitations on gopDuration as well. Valid range is [60, 600].

Returns:

  • (::Integer) —

    Select the GOP size based on the specified frame count. If GOP frame count is set instead of GOP duration, GOP duration will be calculated by gopFrameCount/frameRate. The calculated GOP duration must satisfy the limitations on gopDuration as well. Valid range is [60, 600].

#profile ⇒ ::String

Returns Enforces the specified codec profile. The following profiles are supported:
