Class VideoStream.H265CodecSettings (0.77.0)

H265 codec settings.

Protobuf type google.cloud.video.livestream.v1.VideoStream.H265CodecSettings

Optional. 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.

double aq_strength = 13 [(.google.api.field_behavior) = OPTIONAL];

Optional. The number of consecutive B-frames. Must be greater than or equal to zero. Must be less than gop_frame_count if set. The default is 0.

int32 b_frame_count = 12 [(.google.api.field_behavior) = OPTIONAL];

Optional. Allow B-pyramid for reference frame selection. This may not be supported on all decoders. The default is false.

bool b_pyramid = 11 [(.google.api.field_behavior) = OPTIONAL];

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).
• For UHD resolution (<= 2160p), must be <= 25,000,000 (25 Mbps).

int32 bitrate_bps = 4 [(.google.api.field_behavior) = REQUIRED];

Required. The target video frame rate in frames per second (FPS). Must be less than or equal to 120. 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.

double frame_rate = 3 [(.google.api.field_behavior) = REQUIRED];

Optional. 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.

.google.protobuf.Duration gop_duration = 8 [(.google.api.field_behavior) = OPTIONAL];

Optional. 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.

.google.protobuf.Duration gop_duration = 8 [(.google.api.field_behavior) = OPTIONAL];

Optional. 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].

int32 gop_frame_count = 7 [(.google.api.field_behavior) = OPTIONAL];

Optional. The height of the video in pixels. Must be an even integer. When not specified, the height is adjusted to match the specified width and input aspect ratio. If both are omitted, the input height is used. Valid range is [180, 2160].

int32 height_pixels = 2 [(.google.api.field_behavior) = OPTIONAL];

Optional. Initial fullness of the Video Buffering Verifier (VBV) buffer in bits. Must be greater than zero. The default is equal to 90% of vbv_size_bits.

int32 vbv_fullness_bits = 10 [(.google.api.field_behavior) = OPTIONAL];

Optional. Size of the Video Buffering Verifier (VBV) buffer in bits. Must be greater than zero. The default is equal to bitrate_bps.

int32 vbv_size_bits = 9 [(.google.api.field_behavior) = OPTIONAL];

Optional. The width of the video in pixels. Must be an even integer. When not specified, the width is adjusted to match the specified height and input aspect ratio. If both are omitted, the input width is used. Valid range is [320, 4096].

int32 width_pixels = 1 [(.google.api.field_behavior) = OPTIONAL];

Optional. 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.

.google.protobuf.Duration gop_duration = 8 [(.google.api.field_behavior) = OPTIONAL];

Optional. 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].

int32 gop_frame_count = 7 [(.google.api.field_behavior) = OPTIONAL];
