Properties

ColumnCount

public int ColumnCount { get; set; }

The maximum number of sprites per row in a sprite sheet. The default is 0, which indicates no maximum limit.

Property Value
TypeDescription
Int32

EndTimeOffset

public Duration EndTimeOffset { get; set; }

End time in seconds, relative to the output file timeline. When end_time_offset is not specified, the sprites are generated until the end of the output file.

Property Value
TypeDescription
Duration

ExtractionStrategyCase

public SpriteSheet.ExtractionStrategyOneofCase ExtractionStrategyCase { get; }
Property Value
TypeDescription
SpriteSheet.ExtractionStrategyOneofCase

FilePrefix

public string FilePrefix { get; set; }

Required. File name prefix for the generated sprite sheets.

Each sprite sheet has an incremental 10-digit zero-padded suffix starting from 0 before the extension, such as sprite_sheet0000000123.jpeg.

Property Value
TypeDescription
String

Format

public string Format { get; set; }

Format type. The default is jpeg.

Supported formats:

  • jpeg
Property Value
TypeDescription
String

Interval

public Duration Interval { get; set; }

Starting from 0s, create sprites at regular intervals. Specify the interval value in seconds.

Property Value
TypeDescription
Duration

Quality

public int Quality { get; set; }

The quality of the generated sprite sheet. Enter a value between 1 and 100, where 1 is the lowest quality and 100 is the highest quality. The default is 100. A high quality value corresponds to a low image data compression ratio.

Property Value
TypeDescription
Int32

RowCount

public int RowCount { get; set; }

The maximum number of rows per sprite sheet. When the sprite sheet is full, a new sprite sheet is created. The default is 0, which indicates no maximum limit.

Property Value
TypeDescription
Int32

SpriteHeightPixels

public int SpriteHeightPixels { get; set; }

Required. The height of sprite in pixels. Must be an even integer. To preserve the source aspect ratio, set the [SpriteSheet.sprite_height_pixels][google.cloud.video.transcoder.v1.SpriteSheet.sprite_height_pixels] field or the [SpriteSheet.sprite_width_pixels][google.cloud.video.transcoder.v1.SpriteSheet.sprite_width_pixels] field, but not both (the API will automatically calculate the missing field).

For portrait videos that contain horizontal ASR and rotation metadata, provide the height, in pixels, per the horizontal ASR. The API calculates the width per the horizontal ASR. The API detects any rotation metadata and swaps the requested height and width for the output.

Property Value
TypeDescription
Int32

SpriteWidthPixels

public int SpriteWidthPixels { get; set; }

Required. The width of sprite in pixels. Must be an even integer. To preserve the source aspect ratio, set the [SpriteSheet.sprite_width_pixels][google.cloud.video.transcoder.v1.SpriteSheet.sprite_width_pixels] field or the [SpriteSheet.sprite_height_pixels][google.cloud.video.transcoder.v1.SpriteSheet.sprite_height_pixels] field, but not both (the API will automatically calculate the missing field).

For portrait videos that contain horizontal ASR and rotation metadata, provide the width, in pixels, per the horizontal ASR. The API calculates the height per the horizontal ASR. The API detects any rotation metadata and swaps the requested height and width for the output.

Property Value
TypeDescription
Int32

StartTimeOffset

public Duration StartTimeOffset { get; set; }

Start time in seconds, relative to the output file timeline. Determines the first sprite to pick. The default is 0s.

Property Value
TypeDescription
Duration

TotalCount

public int TotalCount { get; set; }

Total number of sprites. Create the specified number of sprites distributed evenly across the timeline of the output media. The default is 100.

Property Value
