[ aws . kinesis-video-archived-media ]

get-clip

Description

Downloads an MP4 file (clip) containing the archived, on-demand media from the specified video stream over the specified time range.

Both the StreamName and the StreamARN parameters are optional, but you must specify either the StreamName or the StreamARN when invoking this API operation.

As a prerequsite to using GetCLip API, you must obtain an endpoint using GetDataEndpoint , specifying GET_CLIP forthe APIName parameter.

An Amazon Kinesis video stream has the following requirements for providing data through MP4:

  • The media must contain h.264 or h.265 encoded video and, optionally, AAC or G.711 encoded audio. Specifically, the codec ID of track 1 should be V_MPEG/ISO/AVC (for h.264) or V_MPEGH/ISO/HEVC (for H.265). Optionally, the codec ID of track 2 should be A_AAC (for AAC) or A_MS/ACM (for G.711).
  • Data retention must be greater than 0.
  • The video track of each fragment must contain codec private data in the Advanced Video Coding (AVC) for H.264 format and HEVC for H.265 format. For more information, see MPEG-4 specification ISO/IEC 14496-15 . For information about adapting stream data to a given format, see NAL Adaptation Flags .
  • The audio track (if present) of each fragment must contain codec private data in the AAC format (AAC specification ISO/IEC 13818-7 ) or the MS Wave format .

You can monitor the amount of outgoing data by monitoring the GetClip.OutgoingBytes Amazon CloudWatch metric. For information about using CloudWatch to monitor Kinesis Video Streams, see Monitoring Kinesis Video Streams . For pricing information, see Amazon Kinesis Video Streams Pricing and AWS Pricing . Charges for outgoing AWS data apply.

Synopsis

  get-clip
[--stream-name <value>]
[--stream-arn <value>]
--clip-fragment-selector <value>
<outfile>

Options

--stream-name (string)

The name of the stream for which to retrieve the media clip.

You must specify either the StreamName or the StreamARN.

--stream-arn (string)

The Amazon Resource Name (ARN) of the stream for which to retrieve the media clip.

You must specify either the StreamName or the StreamARN.

--clip-fragment-selector (structure)

The time range of the requested clip and the source of the timestamps.

FragmentSelectorType -> (string)

The origin of the timestamps to use (Server or Producer).

TimestampRange -> (structure)

The range of timestamps to return.

StartTimestamp -> (timestamp)

The starting timestamp in the range of timestamps for which to return fragments.

This value is inclusive. Fragments that start before the StartTimestamp and continue past it are included in the session. If FragmentSelectorType is SERVER_TIMESTAMP , the StartTimestamp must be later than the stream head.

EndTimestamp -> (timestamp)

The end of the timestamp range for the requested media.

This value must be within 3 hours of the specified StartTimestamp , and it must be later than the StartTimestamp value. If FragmentSelectorType for the request is SERVER_TIMESTAMP , this value must be in the past.

This value is inclusive. The EndTimestamp is compared to the (starting) timestamp of the fragment. Fragments that start before the EndTimestamp value and continue past it are included in the session.

Shorthand Syntax:

FragmentSelectorType=string,TimestampRange={StartTimestamp=timestamp,EndTimestamp=timestamp}

JSON Syntax:

{
  "FragmentSelectorType": "PRODUCER_TIMESTAMP"|"SERVER_TIMESTAMP",
  "TimestampRange": {
    "StartTimestamp": timestamp,
    "EndTimestamp": timestamp
  }
}

outfile (string) Filename where the content will be saved

See 'aws help' for descriptions of global parameters.

Output

ContentType -> (string)

The content type of the media in the requested clip.

Payload -> (blob)

Traditional MP4 file that contains the media clip from the specified video stream. The output will contain the first 100 MB or the first 200 fragments from the specified start timestamp. For more information, see Kinesis Video Streams Limits .
