H264 codec settings.
Fields
width_pixels: i32
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: i32
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: f64
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 for more information.
bitrate_bps: i32
Required. The video bitrate in bits per second. The minimum value is 1,000. The maximum value is 800,000,000.
pixel_format: String
Pixel format to use. The default is yuv420p
.
Supported pixel formats:
yuv420p
pixel formatyuv422p
pixel formatyuv444p
pixel formatyuv420p10
10-bit HDR pixel formatyuv422p10
10-bit HDR pixel formatyuv444p10
10-bit HDR pixel formatyuv420p12
12-bit HDR pixel formatyuv422p12
12-bit HDR pixel formatyuv444p12
12-bit HDR pixel format
rate_control_mode: String
Specify the rate_control_mode
. The default is vbr
.
Supported rate control modes:
vbr
- variable bitratecrf
- constant rate factor
crf_level: i32
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
.
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: i32
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: i32
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
.
entropy_coder: String
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: i32
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: f64
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: String
Enforces the specified codec profile. The following profiles are supported:
baseline
main
high
(default)
The available options are
[FFmpeg-compatible](https://trac.ffmpeg.org/wiki/Encode/H.264#Tune).
Note that certain values for this field may cause the
transcoder to override other fields you set in the H264CodecSettings
message.
tune: String
Enforces the specified codec tune. The available options are
[FFmpeg-compatible](https://trac.ffmpeg.org/wiki/Encode/H.264#Tune).
Note that certain values for this field may cause the
transcoder to override other fields you set in the H264CodecSettings
message.
preset: String
Enforces the specified codec preset. The default is veryfast
. The
available options are
[FFmpeg-compatible](https://trac.ffmpeg.org/wiki/Encode/H.264#Preset).
Note that certain values for this field may cause the
transcoder to override other fields you set in the H264CodecSettings
message.
gop_mode: Option<GopMode>
GOP mode can be either by frame count or duration.
