Vp9CodecSettings(mapping=None, *, ignore_unknown_fields=False, **kwargs)VP9 codec settings.
Attributes | |
|---|---|
| Name | Description |
width_pixels |
int
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. |
height_pixels |
int
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. |
frame_rate |
float
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 |
bitrate_bps |
int
Required. The video bitrate in bits per second. The minimum value is 1,000. The maximum value is 480,000,000. |
pixel_format |
str
Pixel format to use. The default is yuv420p.
Supported pixel formats:
- yuv420p pixel format
- yuv422p pixel format
- yuv444p pixel format
- yuv420p10 10-bit HDR pixel format
- yuv422p10 10-bit HDR pixel format
- yuv444p10 10-bit HDR pixel format
- yuv420p12 12-bit HDR pixel format
- yuv422p12 12-bit HDR pixel format
- yuv444p12 12-bit HDR pixel format
|
rate_control_mode |
str
Specify the rate_control_mode. The default is vbr.
Supported rate control modes:
- vbr - variable bitrate
- crf - constant rate factor
|
crf_level |
int
Target CRF level. Must be between 10 and 36, where 10 is the highest quality and 36 is the most efficient compression. The default is 21. |
gop_frame_count |
int
Select the GOP size based on the specified frame count. Must be greater than zero. |
gop_duration |
google.protobuf.duration_pb2.Duration
Select the GOP size based on the specified duration. The default is 3s. Note that gopDuration must be less
than or equal to segmentDuration` <#segmentsettings>__ must be
divisible by gopDuration.
|
profile |
str
Enforces the specified codec profile. The following profiles are supported: - profile0 (default)
- profile1
- profile2
- profile3
The available options are
WebM-compatible __.
Note that certain values for this field may cause the
