H264RateControl

class aws_cdk.aws_medialive_alpha.H264RateControl(*args: Any, **kwargs)

Bases: object

(experimental) H.264 rate control. Use the static factory methods to create.

Stability:: experimental
ExampleMetadata:: infused

Example:

# stack: Stack
# input: medialive.IInput
# bucket: s3.IBucket


video = medialive.EncodeConfiguration.video(
    name="video_720p",
    codec=medialive.VideoCodecSettings.h264(
        rate_control=medialive.H264RateControl.cbr(bitrate=Bitrate.mbps(3)),
        framerate=medialive.Framerate.FPS_30
    ),
    width=1280,
    height=720
)

audio = medialive.EncodeConfiguration.audio(
    name="audio_aac",
    codec=medialive.AudioCodecSettings.aac(bitrate=Bitrate.kbps(192))
)

medialive.Channel(stack, "Channel",
    inputs=[medialive.InputAttachment(input=input)],
    output_groups=[
        medialive.OutputGroupConfiguration.hls(
            name="hls",
            destinations=[medialive.OutputDestination.to_bucket(bucket, "live/stream")],

Static Methods

classmethod cbr(*, bitrate)

(experimental) Constant bitrate.

Parameters:: bitrate (Bitrate) – (experimental) The constant bitrate.
Stability:: experimental
Return type:: H264RateControl

classmethod qvbr(*, max_bitrate, qvbr_quality_level=None)

(experimental) Quality-defined variable bitrate.

Parameters:

max_bitrate (Bitrate) – (experimental) The maximum bitrate.
qvbr_quality_level (Union[int, float, None]) – (experimental) The QVBR quality level (1-10). Leave unset to let MediaLive infer the target quality from the output resolution and max bitrate. Default: - MediaLive infers the quality level from the resolution and max bitrate

Stability:

experimental

Return type:

H264RateControl

classmethod vbr(*, bitrate, max_bitrate)

(experimental) Variable bitrate.

Parameters:

bitrate (Bitrate) – (experimental) The average bitrate.
max_bitrate (Bitrate) – (experimental) The maximum bitrate.

Stability:

experimental

Return type:

H264RateControl
