// GetHLSStreamingSessionURL API operation for Amazon Kinesis Video Streams Archived Media.
//
// 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.
//
// You must specify either the StreamName or the StreamARN.
//
// An Amazon Kinesis video stream has the following requirements for providing
// data through HLS:
//
//    * The media type must be video/h264.
//
//    * Data retention must be greater than 0.
//
//    * The fragments must contain codec private data in the AVC (Advanced Video
//    Coding) for H.264 format (MPEG-4 specification ISO/IEC 14496-15 (https://www.iso.org/standard/55980.html)).
//    For information about adapting stream data to a given format, see NAL
//    Adaptation Flags (http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/latest/dg/producer-reference-nal.html).
//
// Kinesis Video Streams HLS sessions contain fragments in the fragmented MPEG-4
// form (also called fMP4 or CMAF), rather than 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 (https://tools.ietf.org/html/draft-pantos-http-live-streaming-23).
//
// The following procedure shows how to use HLS with Kinesis Video Streams:
//
// Get an endpoint using GetDataEndpoint (http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/API_GetDataEndpoint.html),
// specifying GET_HLS_STREAMING_SESSION_URL for the APIName 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 AWS 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 bit rates) 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 decoder and renderer. The media fragments contain H.264-encoded
// video frames and time stamps.
//
// 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, and additional metadata for the media
// player, including estimated bit rate 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 the GetMP4MediaFragment actions.
// The HLS media playlist also contains metadata about the stream that the player
// needs to play it, such as whether the PlaybackMode is LIVE or ON_DEMAND.
// The HLS media playlist is typically static for sessions with a PlaybackType
// of ON_DEMAND. The HLS media playlist is continually updated with new fragments
// for sessions with a PlaybackType of LIVE.
//
// 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, which
// the media player needs to decode video frames.
//
// GetMP4MediaFragment: Retrieves MP4 media fragments. These fragments contain
// the "moof" and "mdat" MP4 atoms and their child atoms, containing the encoded
// fragment's video frames and their time stamps.
//
// After the first media fragment is made available in a streaming session,
// any fragments that don't contain the same codec private data are excluded
// in the HLS media playlist. Therefore, the codec private data does not change
// between fragments in a session.
//
// Data retrieved with this action is billable. See Pricing (aws.amazon.comkinesis/video-streams/pricing/)
// for details.
//
// The following restrictions apply to HLS sessions:
//
// A streaming session URL should 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 (http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/limits.html).
//
// A Kinesis video stream can have a maximum of five active HLS streaming sessions.
// If a new session is created when the maximum number of sessions is already
// active, the oldest (earliest created) session is closed. The number of active
// GetMedia connections on a Kinesis video stream does not count against this
// limit, and the number of active HLS sessions does not count against the active
// GetMedia connection limit.
//
// 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 (http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/monitoring.html).
// For pricing information, see Amazon Kinesis Video Streams Pricing (https://aws.amazon.com/kinesis/video-streams/pricing/)
// and AWS Pricing (https://aws.amazon.com/pricing/). Charges for both HLS sessions
// and outgoing AWS data apply.
//
// For more information about HLS, see HTTP Live Streaming (https://developer.apple.com/streaming/)
// on the Apple Developer site (https://developer.apple.com).
