• vp9

  :type: str

Attributes
Name	Description
profile	str Enforces the specified codec profile. The following profiles are supported: - baseline - main - high (default) 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 VideoStream 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 VideoStream 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 VideoStream message.
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.
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.
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.
bitrate_bps	int Required. The video bitrate in bits per second. The minimum value is 1,000. The maximum value for H264/H265 is 800,000,000. The maximum value for VP9 is 480,000,000.
rate_control_mode	str Specify the rate_control_mode. The default is "vbr". Supported rate control modes: - 'vbr' - variable bitrate - 'crf' - constant rate factor
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.
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.
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.
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.
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>__, and segmentDuration` <#segmentsettings>__ must be divisible by gopDuration.
entropy_coder	str The entropy coder to use. The default is "cabac". Supported entropy coders: - 'cavlc' - 'cabac'
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.
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 `Calculate frame rate
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.
