H264CodecSettings(mapping=None, *, ignore_unknown_fields=False, **kwargs)H264 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
Required. The width of the video in pixels. Must be an even integer. Valid range is [320, 1920]. |
height_pixels |
int
Required. The height of the video in pixels. Must be an even integer. Valid range is [180, 1080]. |
frame_rate |
float
Required. The target video frame rate in frames per second (FPS). Must be less than or equal to 60. 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. Minimum value is 10,000. - For SD resolution (< 720p),="" must="" be=""><= 3,000,000="" (3="" mbps).="" -="" for="" hd="" resolution=""><= 1080p),="" must="" be=""><= 15,000,000="" (15="" mbps).=""> |
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. If GOP frame count is set instead of GOP duration, GOP duration will be calculated by gopFrameCount/frameRate. The
calculated GOP duration must satisfy the limitations on
gopDuration as well. Valid range is [60, 600].
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 2s. Note that gopDuration must be less
than or equal to
segment_duration,
and
segment_duration
must be divisible by gopDuration. Valid range is [2s,
20s].
All video streams in the same channel must have the same GOP
size.
This field is a member of oneof_ gop_mode.
|
vbv_size_bits |
int
Size of the Video Buffering Verifier (VBV) buffer in bits. Must be greater than zero. The default is equal to 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 vbv_size_bits. |
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 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: - baseline
- main (default)
- high
The available options are `FFmpeg-compatible Profile
Options |
tune |
str
Enforces the specified codec tune. The available options are `FFmpeg-compatible Encode Options |
