Methods

getAllowOpenGop()

public abstract boolean getAllowOpenGop()

Specifies whether an open Group of Pictures (GOP) structure should be allowed or not. The default is false.

bool allow_open_gop = 6;

Returns
Type	Description
boolean	The allowOpenGop.

getAqStrength()

public abstract double getAqStrength()

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 = 14;

Returns
Type	Description
double	The aqStrength.

getBFrameCount()

public abstract int getBFrameCount()

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 = 13;

Returns
Type	Description
int	The bFrameCount.

getBPyramid()

public abstract boolean getBPyramid()

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

bool b_pyramid = 12;

Returns
Type	Description
boolean	The bPyramid.

getBitrateBps()

public abstract int getBitrateBps()

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).

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

Returns
Type	Description
int	The bitrateBps.

getEntropyCoder()

public abstract String getEntropyCoder()

The entropy coder to use. The default is cabac.

Supported entropy coders:

• cavlc
• cabac

string entropy_coder = 11;

Returns
Type	Description
String	The entropyCoder.

getEntropyCoderBytes()

public abstract ByteString getEntropyCoderBytes()

The entropy coder to use. The default is cabac.

Supported entropy coders:

• cavlc
• cabac

string entropy_coder = 11;

Returns
Type	Description
ByteString	The bytes for entropyCoder.

getFrameRate()

public abstract double getFrameRate()

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.

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

Returns
Type	Description
double	The frameRate.

getGopDuration()

public abstract Duration getGopDuration()

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;

Returns
Type	Description
Duration	The gopDuration.

getGopDurationOrBuilder()

public abstract DurationOrBuilder getGopDurationOrBuilder()

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;

Returns
Type	Description
DurationOrBuilder

getGopFrameCount()

public abstract int getGopFrameCount()

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;

Returns
Type	Description
int	The gopFrameCount.

getGopModeCase()

Returns
Type	Description
VideoStream.H264CodecSettings.GopModeCase

getHeightPixels()

public abstract int getHeightPixels()

Required. The height of the video in pixels. Must be an even integer. Valid range is [180, 1080].

int32 height_pixels = 2;

Returns
Type	Description
int	The heightPixels.

getProfile()

public abstract String getProfile()

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

• baseline
• main (default)

• high

string profile = 15;

Returns
Type	Description

getProfileBytes()

public abstract ByteString getProfileBytes()

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