  # H264 codec settings.
  # @!attribute [rw] width_pixels
  #   @return [::Integer]
  #     Required. The width of the video in pixels. Must be an even integer.
  #     Valid range is [320, 1920].
  # @!attribute [rw] height_pixels
  #   @return [::Integer]
  #     Required. The height of the video in pixels. Must be an even integer.
  #     Valid range is [180, 1080].
  # @!attribute [rw] frame_rate
  #   @return [::Float]
  #     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](https://cloud.google.com/transcoder/docs/concepts/frame-rate) for
  #     more information.
  # @!attribute [rw] bitrate_bps
  #   @return [::Integer]
  #     Required. The video bitrate in bits per second. Minimum value is 10,000.
  #
  #     - For SD resolution (< 720p), must be <= 3,000,000 (3 Mbps).
  #     - For HD resolution (<= 1080p), must be <= 15,000,000 (15 Mbps).
  # @!attribute [rw] allow_open_gop
  #   @return [::Boolean]
  #     Specifies whether an open Group of Pictures (GOP) structure should be
  #     allowed or not. The default is `false`.
  # @!attribute [rw] gop_frame_count
  #   @return [::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].
  # @!attribute [rw] gop_duration
  #   @return [::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
  #     {::Google::Cloud::Video::LiveStream::V1::SegmentSettings#segment_duration segment_duration},
  #     and
  #     {::Google::Cloud::Video::LiveStream::V1::SegmentSettings#segment_duration 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.
  # @!attribute [rw] vbv_size_bits
  #   @return [::Integer]
  #     Size of the Video Buffering Verifier (VBV) buffer in bits. Must be
  #     greater than zero. The default is equal to
  #     {::Google::Cloud::Video::LiveStream::V1::VideoStream::H264CodecSettings#bitrate_bps bitrate_bps}.
  # @!attribute [rw] vbv_fullness_bits
  #   @return [::Integer]
  #     Initial fullness of the Video Buffering Verifier (VBV) buffer in bits.
  #     Must be greater than zero. The default is equal to 90% of
  #     {::Google::Cloud::Video::LiveStream::V1::VideoStream::H264CodecSettings#vbv_size_bits vbv_size_bits}.
  # @!attribute [rw] entropy_coder
  #   @return [::String]
  #     The entropy coder to use. The default is `cabac`.
  #
  #     Supported entropy coders:
  #
  #     - `cavlc`
  #     - `cabac`
  # @!attribute [rw] b_pyramid
  #   @return [::Boolean]
  #     Allow B-pyramid for reference frame selection. This may not be supported
  #     on all decoders. The default is `false`.
  # @!attribute [rw] b_frame_count
  #   @return [::Integer]
  #     The number of consecutive B-frames. Must be greater than or equal to
  #     zero. Must be less than
  #     {::Google::Cloud::Video::LiveStream::V1::VideoStream::H264CodecSettings#gop_frame_count gop_frame_count}
  #     if set. The default is 0.
  # @!attribute [rw] aq_strength
  #   @return [::Float]
  #     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.
  # @!attribute [rw] profile
  #   @return [::String]
  #     Enforces the specified codec profile. The following profiles are
  #     supported:
  #
  #     *   `baseline`
  #     *   `main` (default)
  #     *   `high`
  #
  #     The available options are [FFmpeg-compatible Profile
  #     Options](https://trac.ffmpeg.org/wiki/Encode/H.264#Profile).
  #     Note that certain values for this field may cause the
  #     transcoder to override other fields you set in the
  #     {::Google::Cloud::Video::LiveStream::V1::VideoStream::H264CodecSettings H264CodecSettings}
  #     message.
  # @!attribute [rw] tune
  #   @return [::String]
  #     Enforces the specified codec tune. The available options are
  #     [FFmpeg-compatible Encode
  #     Options](https://trac.ffmpeg.org/wiki/Encode/H.264#Tune)
  #     Note that certain values for this field may cause the transcoder to
