Vp9CodecSettings(mapping=None, *, ignore_unknown_fields=False, **kwargs)VP9 codec settings. .. attribute:: width_pixels
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.
:type: int
Attributes | |
|---|---|
| Name | Description |
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. Must be between 1 and 1,000,000,000. |
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 __\ {:
class="external" }. Note that certain values for this field
may cause the transcoder to override other fields you set in
the Vp9CodecSettings message.
