#get_clip(params = {}) ⇒ Types::GetClipOutput
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 prerequisite to using GetCLip API, you must obtain an endpoint
using GetDataEndpoint
, specifying GET_CLIP forthe APIName
parameter. </p> 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

An Amazon Kinesis video stream has the following requirements for providing data through MPEG-DASH:
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 beA_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.
The following procedure shows how to use MPEG-DASH with Kinesis Video Streams:
Get an endpoint using GetDataEndpoint, specifying
GET_DASH_STREAMING_SESSION_URL
for theAPIName
parameter.Retrieve the MPEG-DASH URL using
GetDASHStreamingSessionURL
. Kinesis Video Streams creates an MPEG-DASH streaming session to be used for accessing content in a stream using the MPEG-DASH protocol.GetDASHStreamingSessionURL
returns an authenticated URL (that includes an encrypted session token) for the session's MPEG-DASH manifest (the root resource needed for streaming with MPEG-DASH).Don't share or store this token where an unauthorized entity can access it. The token provides access to the content of the stream. Safeguard the token with the same measures that you use with your Amazon Web Services credentials. The media that is made available through the manifest consists only of the requested stream, time range, and format. No other media data (such as frames outside the requested window or alternate bitrates) is made available.
Provide the URL (containing the encrypted session token) for the MPEG-DASH manifest to a media player that supports the MPEG-DASH protocol. Kinesis Video Streams makes the initialization fragment and media fragments available through the manifest URL. The initialization fragment contains the codec private data for the stream, and other data needed to set up the video or audio decoder and renderer. The media fragments contain encoded video frames or encoded audio samples.
The media player receives the authenticated URL and requests stream metadata and media data normally. When the media player requests data, it calls the following actions:
GetDASHManifest: Retrieves an MPEG DASH manifest, which contains the metadata for the media that you want to playback.
GetMP4InitFragment: Retrieves the MP4 initialization fragment. The media player typically loads the initialization fragment before loading any media fragments. This fragment contains the "
fytp
" and "moov
" MP4 atoms, and the child atoms that are needed to initialize the media player decoder.The initialization fragment does not correspond to a fragment in a Kinesis video stream. It contains only the codec private data for the stream and respective track, which the media player needs to decode the media frames.
GetMP4MediaFragment: Retrieves MP4 media fragments. These fragments contain the "
moof
" and "mdat
" MP4 atoms and their child atoms, containing the encoded fragment's media frames and their timestamps.After the first media fragment is made available in a streaming session, any fragments that don't contain the same codec private data cause an error to be returned when those different media fragments are loaded. Therefore, the codec private data should not change between fragments in a session. This also means that the session fails if the fragments in a stream change from having only video to having both audio and video. Data retrieved with this action is billable. See Pricing for details.
You can monitor the amount of data that the media player consumes by
monitoring the GetMP4MediaFragment.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 Amazon
Web Services Pricing. Charges for both HLS sessions and outgoing
Amazon Web Services data apply.
For more information about HLS, see HTTP Live Streaming on the Apple Developer site.
If an error is thrown after invoking a Kinesis Video Streams archived media API, in addition to the HTTP status code and the response body, it includes the following pieces of information:
x-amz-ErrorType
HTTP header – contains a more specific error type in addition to what the HTTP status code provides.x-amz-RequestId
HTTP header – if you want to report an issue to Amazon Web Services the support team can better diagnose the problem if given the Request Id.
Both the HTTP status code and the ErrorType header can be utilized to make programmatic decisions about whether errors are retry-able and under what conditions, as well as provide information on what actions the client programmer might need to take in order to successfully try again.
For more information, see the Errors section at the bottom of this topic, as well as Common Errors.

#get_hls_streaming_session_url(params = {}) ⇒ Types::GetHLSStreamingSessionURLOutput
Retrieves an HTTP Live Streaming (HLS) URL for the stream. You can then open the URL in a browser or media player to view the stream contents.
Both the StreamName
and the StreamARN
parameters are optional, but
you must specify either the StreamName
or the StreamARN
when

An Amazon Kinesis video stream has the following requirements for providing data through HLS:
For streaming video, the media must contain H.264 or H.265 encoded video and, optionally, AAC encoded audio. Specifically, the codec ID of track 1 should be
V_MPEG/ISO/AVC
(for H.264) orV_MPEG/ISO/HEVC
(for H.265). Optionally, the codec ID of track 2 should beA_AAC
. For audio only streaming, the codec ID of track 1 should beA_AAC
.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 or HEVC for H.265 format (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).
Kinesis Video Streams HLS sessions contain fragments in the fragmented MPEG-4 form (also called fMP4 or CMAF) or the MPEG-2 form (also called TS chunks, which the HLS specification also supports). For more information about HLS fragment types, see the HLS specification.
The following procedure shows how to use HLS with Kinesis Video Streams:
Get an endpoint using GetDataEndpoint, specifying
GET_HLS_STREAMING_SESSION_URL
for theAPIName
parameter.Retrieve the HLS URL using
GetHLSStreamingSessionURL
. Kinesis Video Streams creates an HLS streaming session to be used for accessing content in a stream using the HLS protocol.GetHLSStreamingSessionURL
returns an authenticated URL (that includes an encrypted session token) for the session's HLS master playlist (the root resource needed for streaming with HLS).Don't share or store this token where an unauthorized entity could access it. The token provides access to the content of the stream. Safeguard the token with the same measures that you would use with your Amazon Web Services credentials. The media that is made available through the playlist consists only of the requested stream, time range, and format. No other media data (such as frames outside the requested window or alternate bitrates) is made available.
Provide the URL (containing the encrypted session token) for the HLS master playlist to a media player that supports the HLS protocol. Kinesis Video Streams makes the HLS media playlist, initialization fragment, and media fragments available through the master playlist URL. The initialization fragment contains the codec private data for the stream, and other data needed to set up the video or audio decoder and renderer. The media fragments contain H.264-encoded video frames or AAC-encoded audio samples.
The media player receives the authenticated URL and requests stream metadata and media data normally. When the media player requests data, it calls the following actions:
GetHLSMasterPlaylist: Retrieves an HLS master playlist, which contains a URL for the
GetHLSMediaPlaylist
action for each track, and additional metadata for the media player, including estimated bitrate and resolution.GetHLSMediaPlaylist: Retrieves an HLS media playlist, which contains a URL to access the MP4 initialization fragment with the
GetMP4InitFragment
action, and URLs to access the MP4 media fragments with theGetMP4MediaFragment
actions. The HLS media playlist also contains metadata about the stream that the player needs to play it, such as whether thePlaybackMode
isLIVE
orON_DEMAND
. The HLS media playlist is typically static for sessions with aPlaybackType
ofON_DEMAND
. The HLS media playlist is continually updated with new fragments for sessions with aPlaybackType
ofLIVE
. There is a distinct HLS media playlist for the video track and the audio track (if applicable) that contains MP4 media URLs for the specific track.GetMP4InitFragment: Retrieves the MP4 initialization fragment. The media player typically loads the initialization fragment before loading any media fragments. This fragment contains the "
fytp
" and "moov
" MP4 atoms, and the child atoms that are needed to initialize the media player decoder.The initialization fragment does not correspond to a fragment in a Kinesis video stream. It contains only the codec private data for the stream and respective track, which the media player needs to decode the media frames.
GetMP4MediaFragment: Retrieves MP4 media fragments. These fragments contain the "
moof
" and "mdat
" MP4 atoms and their child atoms, containing the encoded fragment's media frames and their timestamps.For the HLS streaming session, in-track codec private data (CPD) changes are supported. After the first media fragment is made available in a streaming session, fragments can contain CPD changes for each track. Therefore, the fragments in a session can have a different resolution, bit rate, or other information in the CPD without interrupting playback. However, any change made in the track number or track codec format can return an error when those different media fragments are loaded. For example, streaming will fail if the fragments in the stream change from having only video to having both audio and video, or if an AAC audio track is changed to an ALAW audio track. For each streaming session, only 500 CPD changes are allowed. Data retrieved with this action is billable. For information, see Pricing.
GetTSFragment: Retrieves MPEG TS fragments containing both initialization and media data for all tracks in the stream.
If the ContainerFormat
isMPEG_TS
, this API is used instead ofGetMP4InitFragment
andGetMP4MediaFragment
to retrieve stream media.Data retrieved with this action is billable. For more information, see Kinesis Video Streams pricing.
A streaming session URL must not be shared between players. The service might throttle a session if multiple media players are sharing it. For connection limits, see Kinesis Video Streams Limits.
You can monitor the amount of data that the media player consumes by
monitoring the GetMP4MediaFragment.OutgoingBytes
