H265CodecSettings(mapping=None, *, ignore_unknown_fields=False, **kwargs)H265 codec settings.
This message has oneof_ fields (mutually exclusive fields).
For each oneof, at most one member field can be set at the same time.
Setting any member of the oneof automatically clears all other
members.

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. 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. |
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. 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. |
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 800,000,000. |
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. |
allow_open_gop |
bool
Specifies whether an open Group of Pictures (GOP) structure should be allowed or not. The default is false.
|
gop_frame_count |
int
Select the GOP size based on the specified frame count. Must be greater than zero. This field is a member of oneof_ gop_mode.
|
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.
This field is a member of oneof_ gop_mode.
|
enable_two_pass |
bool
Use two-pass encoding strategy to achieve better video quality. VideoStream.rate_control_mode must be vbr.
The default is false.
|
vbv_size_bits |
int
Size of the Video Buffering Verifier (VBV) buffer in bits. Must be greater than zero. The default is equal to VideoStream.bitrate_bps.
|
vbv_fullness_bits |
int
Initial fullness of the Video Buffering Verifier (VBV) buffer in bits. Must be greater than zero. The default is equal to 90% of VideoStream.vbv_size_bits.
|
b_pyramid |
bool
Allow B-pyramid for reference frame selection. This may not be supported on all decoders. The default is false.
|
b_frame_count |
int
The number of consecutive B-frames. Must be greater than or equal to zero. Must be less than VideoStream.gop_frame_count if set. The default is 0.
|
aq_strength |
float
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. |
profile |
str
Enforces the specified codec profile. The following profiles are supported: - 8-bit profiles - main (default)
- main-intra
- mainstillpicture
- 10-bit profiles
- main10 (default)
- main10-intra
- main422-10
- main422-10-intra
- main444-10
- main444-10-intra
- 12-bit profiles
- main12 (default)
- main12-intra
- main422-12
- main422-12-intra
- main444-12
- main444-12-intra
The available options are
FFmpeg-compatible __. Note
that certain values for this field may cause the transcoder
to override other fields you set in the
H265CodecSettings message.
|
tune |
str
Enforces the specified codec tune. The available options are FFmpeg-compatible __.
Note that certain values for this field may cause the
transcoder to override other fields you set in the
H265CodecSettings message.
|
preset |
str
Enforces the specified codec preset. The default is veryfast. The available options are
FFmpeg-compatible __.
Note that certain values for this field may cause the
transcoder to override other fields you set in the
H265CodecSettings message.
