See ‘aws help’ for descriptions of global parameters.

Synopsis

  start-channel
--channel-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--channel-id (string) A request to start a channel

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

The I-frame manifest contains a #EXT-X-I-FRAMES-ONLY tag to indicate it is I-frame only, and one or more #EXT-X-BYTERANGE entries identifying the I-frame position. For example, #EXT-X-BYTERANGE:160364@1461888”

IncompleteSegmentBehavior -> (string)

Specifies whether to include the final (incomplete) segment in the media output when the pipeline stops producing output because of a channel stop, a channel pause or a loss of input to the pipeline. Auto means that MediaLive decides whether to include the final segment, depending on the channel class and the types of output groups. Suppress means to never include the incomplete segment. We recommend you choose Auto and let MediaLive control the behavior.

IvSource -> (string)

For use with encryptionType. The IV (Initialization Vector) is a 128-bit number used in conjunction with the key for encrypting blocks. If this setting is “followsSegmentNumber”, it will cause the IV to change every segment (to match the segment number). If this is set to “explicit”, you must enter a constantIv value.

KeepSegments -> (integer)

Applies only if Mode field is LIVE. Specifies the number of media segments to retain in the destination directory. This number should be bigger than indexNSegments (Num segments). We recommend (value = (2 x indexNsegments) + 1). If this “keep segments” number is too low, the following might happen: the player is still reading a media manifest file that lists this segment, but that segment has been removed from the destination directory (as directed by indexNSegments). This situation would result in a 404 HTTP error on the player.

KeyFormat -> (string)

The value specifies how the key is represented in the resource identified by the URI. If parameter is absent, an implicit value of “identity” is used. A reverse DNS string can also be given.

When set, minimumSegmentLength is enforced by looking ahead and back within the specified range for a nearby avail and extending the segment size if needed.

Mode -> (string)

If “vod”, all segments are indexed and kept permanently in the destination and manifest. If “live”, only the number segments specified in keepSegments and indexNSegments are kept; newer segments replace older segments, which may prevent players from rewinding all the way to the beginning of the event. VOD mode uses HLS EXT-X-PLAYLIST-TYPE of EVENT while the channel is running, converting it to a “VOD” type manifest on completion of the stream.

OutputSelection -> (string)

MANIFESTS_AND_SEGMENTS: Generates manifests (master manifest, if applicable, and media manifests) for this output group. VARIANT_MANIFESTS_AND_SEGMENTS: Generates media manifests for this output group, but not a master manifest. SEGMENTS_ONLY: Does not generate any manifests for this output group.

Options include: INITIALIZE_FROM_OUTPUT_TIMECODE: The PDT clock is initialized as a function of the first output timecode, then incremented by the EXTINF duration of each encoded segment. SYSTEM_CLOCK: The PDT clock is initialized as a function of the UTC wall clock, then incremented by the EXTINF duration of each encoded segment. If the PDT clock diverges from the wall clock by more than 500ms, it is resynchronized to the wall clock.

ProgramDateTimePeriod -> (integer)

Period of insertion of EXT-X-PROGRAM-DATE-TIME entry, in seconds.

RedundantManifest -> (string)

ENABLED: The master manifest (.m3u8 file) for each pipeline includes information about both pipelines: first its own media files, then the media files of the other pipeline. This feature allows playout device that support stale manifest detection to switch from one manifest to the other, when the current manifest seems to be stale. There are still two destinations and two master manifests, but both master manifests reference the media files from both pipelines. DISABLED: The master manifest (.m3u8 file) for each pipeline includes information about its own pipeline only. For an HLS output group with MediaPackage as the destination, the DISABLED behavior is always followed. MediaPackage regenerates the manifests it serves to players so a redundant manifest from MediaLive is irrelevant.

The media manifest includes #EXT-X-BYTERANGE tags to index segments for playback. A typical use for this value is when sending the output to AWS Elemental MediaConvert, which can accept only a single media file. Playback while the channel is running is not guaranteed due to HTTP server caching.

There are three types of adaptive quantization: flicker, spatial, and temporal. Set the field in one of these ways: Set to Auto. Recommended. For each type of AQ, MediaLive will determine if AQ is needed, and if so, the appropriate strength. Set a strength (a value other than Auto or Disable). This strength will apply to any of the AQ fields that you choose to enable. Set to Disabled to disable all types of adaptive quantization.

Strength -> (string)

Choose a filter strength. We recommend a strength of 1 or 2. A higher strength might take out good information, resulting in an image that is overly soft.

FixedAfd -> (string)

Four bit AFD value to write on all frames of video in the output stream. Only valid when afdSignaling is set to ‘Fixed’.

FlickerAq -> (string)

Flicker AQ makes adjustments within each frame to reduce flicker or ‘pop’ on I-frames. The value to enter in this field depends on the value in the Adaptive quantization field: If you have set the Adaptive quantization field to Auto, MediaLive ignores any value in this field. MediaLive will determine if flicker AQ is appropriate and will apply the appropriate strength. If you have set the Adaptive quantization field to a strength, you can set this field to Enabled or Disabled. Enabled: MediaLive will apply flicker AQ using the specified strength. Disabled: MediaLive won’t apply flicker AQ. If you have set the Adaptive quantization to Disabled, MediaLive ignores any value in this field and doesn’t apply flicker AQ.

Softness. Selects quantizer matrix, larger values reduce high-frequency content in the encoded image. If not set to zero, must be greater than 15.

SpatialAq -> (string)

Spatial AQ makes adjustments within each frame based on spatial variation of content complexity. The value to enter in this field depends on the value in the Adaptive quantization field: If you have set the Adaptive quantization field to Auto, MediaLive ignores any value in this field. MediaLive will determine if spatial AQ is appropriate and will apply the appropriate strength. If you have set the Adaptive quantization field to a strength, you can set this field to Enabled or Disabled. Enabled: MediaLive will apply spatial AQ using the specified strength. Disabled: MediaLive won’t apply spatial AQ. If you have set the Adaptive quantization to Disabled, MediaLive ignores any value in this field and doesn’t apply spatial AQ.

TemporalAq -> (string)

Temporal makes adjustments within each frame based on temporal variation of content complexity. The value to enter in this field depends on the value in the Adaptive quantization field: If you have set the Adaptive quantization field to Auto, MediaLive ignores any value in this field. MediaLive will determine if temporal AQ is appropriate and will apply the appropriate strength. If you have set the Adaptive quantization field to a strength, you can set this field to Enabled or Disabled. Enabled: MediaLive will apply temporal AQ using the specified strength. Disabled: MediaLive won’t apply temporal AQ. If you have set the Adaptive quantization to Disabled, MediaLive ignores any value in this field and doesn’t apply temporal AQ.

Enforces separation between repeated (cadence) I-frames and I-frames inserted by Scene Change Detection. If a scene change I-frame is within I-interval frames of a cadence I-frame, the GOP is shrunk and/or stretched to the scene change I-frame. GOP stretch requires enabling lookahead as well as setting I-interval. The normal cadence resumes for the next GOP. Note: Maximum GOP stretch = GOP size + Min-I-interval - 1

ParNumerator -> (integer)

Pixel Aspect Ratio numerator.

Profile -> (string)

DisplayAspectRatio -> (string)

Sets the pixel aspect ratio for the encode.

FilterSettings -> (structure)

Optionally specify a noise reduction filter, which can improve quality of compressed content. If you do not choose a filter, no filter will be applied. TEMPORAL: This filter is useful for both source content that is noisy (when it has excessive digital artifacts) and source content that is clean. When the content is noisy, the filter cleans up the source content before the encoding phase, with these two effects: First, it improves the output video quality because the content has been cleaned up. Secondly, it decreases the bandwidth because MediaLive does not waste bits on encoding noise. When the content is reasonably clean, the filter tends to decrease the bitrate.

TemporalFilterSettings -> (structure)

Temporal Filter Settings

PostFilterSharpening -> (string)

If you enable this filter, the results are the following: - If the source content is noisy (it contains excessive digital artifacts), the filter cleans up the source. - If the source content is already clean, the filter tends to decrease the bitrate, especially when the rate control mode is QVBR.

If gopSizeUnits is frames, then the gopSize must be an integer and must be greater than or equal to 1. If gopSizeUnits is seconds, the gopSize must be greater than 0, but does not need to be an integer.

GopSizeUnits -> (string)

Relates to the GOP structure. Specifies whether the gopSize is specified in frames or seconds. If you do not plan to change the default gopSize, leave the default. If you specify SECONDS, MediaLive will internally convert the gop size to a frame count.

Indicates how MediaLive will respond to the AFD values that might be in the input video. If you do not know what AFD signaling is, or if your downstream system has not given you guidance, choose PASSTHROUGH. RESPOND: MediaLive clips the input video using a formula that uses the AFD values (configured in afdSignaling ), the input display aspect ratio, and the output display aspect ratio. MediaLive also includes the AFD values in the output, unless the codec for this encode is FRAME_CAPTURE. PASSTHROUGH: MediaLive ignores the AFD values and does not clip the video. But MediaLive does include the values in the output. NONE: MediaLive does not clip the input video and does not include the AFD values in the output

ErrorClearTimeMsec -> (integer)

This clear time defines the requirement a recovered input must meet to be considered healthy. The input must have no failover conditions for this length of time. Enter a time in milliseconds. This value is particularly important if the input_preference for the failover pair is set to PRIMARY_INPUT_PREFERRED, because after this time, MediaLive will switch back to the primary input.

A value used in calculating the threshold below which MediaLive considers a pixel to be ‘black’. For the input to be considered black, every pixel in a frame must be below this threshold. The threshold is calculated as a percentage (expressed as a decimal) of white. Therefore .1 means 10% white (or 90% black). Note how the formula works for any color depth. For example, if you set this field to 0.1 in 10-bit color depth: (1023*0.1=102.3), which means a pixel value of 102 or less is ‘black’. If you set this field to .1 in an 8-bit color depth: (255*0.1=25.5), which means a pixel value of 25 or less is ‘black’. The range is 0.0 to 1.0, with any number of decimal places.

You can define a display rectangle for the captions that is smaller than the underlying video frame. You define the rectangle by specifying the position of the left edge, top edge, bottom edge, and right edge of the rectangle, all within the underlying video frame. The units for the measurements are percentages. If you specify a value for one of these fields, you must specify a value for all of them. For leftOffset, specify the position of the left edge of the rectangle, as a percentage of the underlying frame width, and relative to the left edge of the frame. For example, “10” means the measurement is 10% of the underlying frame width. The rectangle left edge starts at that position from the left edge of the frame. This field corresponds to tts:origin - X in the TTML standard.

See the description in leftOffset. For topOffset, specify the position of the top edge of the rectangle, as a percentage of the underlying frame height, and relative to the top edge of the frame. For example, “10” means the measurement is 10% of the underlying frame height. The rectangle top edge starts at that position from the top edge of the frame. This field corresponds to tts:origin - Y in the TTML standard.

Width -> (double)

See the description in leftOffset. For width, specify the entire width of the rectangle as a percentage of the underlying frame width.
