You can then open the URL in a browser or media player to view the stream contents.</p> <p>You must specify either the <code>StreamName</code> or the <code>StreamARN</code>.</p> <p>An Amazon Kinesis video stream has the following requirements for providing data through HLS:</p> <ul> <li> <p>The media must contain h.264 encoded video and, optionally, AAC encoded audio. Specifically, the codec id of track 1 should be <code>V_MPEG/ISO/AVC</code>. Optionally, the codec id of track 2 should be <code>A_AAC</code>.</p> </li> <li> <p>Data retention must be greater than 0.</p> </li> <li> <p>The video track of each fragment must contain codec private data in the Advanced Video Coding (AVC) for H.264 format (<a href="https://www.iso.org/standard/55980.html">MPEG-4 specification ISO/IEC 14496-15</a>). For information about adapting stream data to a given format, see <a href="http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/producer-reference-nal.html">NAL Adaptation Flags</a>.</p> </li> <li> <p>The audio track (if present) of each fragment must contain codec private data in the AAC format (<a href="https://www.iso.org/standard/43345.html">AAC specification ISO/IEC 13818-7</a>).</p> </li> </ul> <p>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 <a href="https://tools.ietf.org/html/draft-pantos-http-live-streaming-23">HLS specification</a>.</p> <p>The following procedure shows how to use HLS with Kinesis Video Streams:</p> <ol> <li> <p>Get an endpoint using <a href="http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/API_GetDataEndpoint.html">GetDataEndpoint</a>, specifying <code>GET_HLS_STREAMING_SESSION_URL</code> for the <code>APIName</code> parameter.</p> </li> <li> <p>Retrieve the HLS URL using <code>GetHLSStreamingSessionURL</code>. Kinesis Video Streams creates an HLS streaming session to be used for accessing content in a stream using the HLS protocol. <code>GetHLSStreamingSessionURL</code> returns an authenticated URL (that includes an encrypted session token) for the session's HLS <i>master playlist</i> (the root resource needed for streaming with HLS).</p> <note> <p>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.</p> </note> <p>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.</p> </li> <li> <p>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.</p> </li> <li> <p>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:</p> <ul> <li> <p> <b>GetHLSMasterPlaylist:</b> Retrieves an HLS master playlist, which contains a URL for the <code>GetHLSMediaPlaylist</code> action for each track, and additional metadata for the media player, including estimated bitrate and resolution.</p> </li> <li> <p> <b>GetHLSMediaPlaylist:</b> Retrieves an HLS media playlist, which contains a URL to access the MP4 initialization fragment with the <code>GetMP4InitFragment</code> action, and URLs to access the MP4 media fragments with the <code>GetMP4MediaFragment</code> actions. The HLS media playlist also contains metadata about the stream that the player needs to play it, such as whether the <code>PlaybackMode</code> is <code>LIVE</code> or <code>ON_DEMAND</code>. The HLS media playlist is typically static for sessions with a <code>PlaybackType</code> of <code>ON_DEMAND</code>. The HLS media playlist is continually updated with new fragments for sessions with a <code>PlaybackType</code> of <code>LIVE</code>. 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. </p> </li> <li> <p> <b>GetMP4InitFragment:</b> Retrieves the MP4 initialization fragment. The media player typically loads the initialization fragment before loading any media fragments. This fragment contains the "<code>fytp</code>" and "<code>moov</code>" MP4 atoms, and the child atoms that are needed to initialize the media player decoder.</p> <p>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.</p> </li> <li> <p> <b>GetMP4MediaFragment:</b> Retrieves MP4 media fragments. These fragments contain the "<code>moof</code>" and "<code>mdat</code>" MP4 atoms and their child atoms, containing the encoded fragment's media frames and their timestamps. </p> <note> <p>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.</p> </note> <p>Data retrieved with this action is billable. See <a href="https://aws.amazon.com/kinesis/video-streams/pricing/">Pricing</a> for details.</p> </li> <li> <p> <b>GetTSFragment:</b> Retrieves MPEG TS fragments containing both initialization and media data for all tracks in the stream.</p> <note> <p>If the <code>ContainerFormat</code> is <code>MPEG_TS</code>, this API is used instead of <code>GetMP4InitFragment</code> and <code>GetMP4MediaFragment</code> to retrieve stream media.</p> </note> <p>Data retrieved with this action is billable. For more information, see <a href="https://aws.amazon.com/kinesis/video-streams/pricing/">Kinesis Video Streams pricing</a>.</p> </li> </ul> </li> </ol> <note> <p>The following restrictions apply to HLS sessions:</p> <ul> <li> <p>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 <a href="http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/limits.html">Kinesis Video Streams Limits</a>.</p> </li> <li> <p>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 <code>GetMedia</code> 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 <code>GetMedia</code> connection limit.</p> </li> </ul> </note> <p>You can monitor the amount of data that the media player consumes by monitoring the <code>GetMP4MediaFragment.OutgoingBytes</code> Amazon CloudWatch metric. For information about using CloudWatch to monitor Kinesis Video Streams, see <a href="http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/monitoring.html">Monitoring Kinesis Video Streams</a>. For pricing information, see <a href="https://aws.amazon.com/kinesis/video-streams/pricing/">Amazon Kinesis Video Streams Pricing</a> and <a href="https://aws.amazon.com/pricing/">AWS Pricing</a>.

You can then open the URL in a browser or media player to view the stream contents.</p> <p>You must specify either the <code>StreamName</code> or the <code>StreamARN</code>.</p> <p>An Amazon Kinesis video stream has the following requirements for providing data through HLS:</p> <ul> <li> <p>The media must contain h.264 encoded video and, optionally, AAC encoded audio. Specifically, the codec id of track 1 should be <code>V_MPEG/ISO/AVC</code>. Optionally, the codec id of track 2 should be <code>A_AAC</code>.</p> </li> <li> <p>Data retention must be greater than 0.</p> </li> <li> <p>The video track of each fragment must contain codec private data in the Advanced Video Coding (AVC) for H.264 format (<a href="https://www.iso.org/standard/55980.html">MPEG-4 specification ISO/IEC 14496-15</a>). For information about adapting stream data to a given format, see <a href="http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/producer-reference-nal.html">NAL Adaptation Flags</a>.</p> </li> <li> <p>The audio track (if present) of each fragment must contain codec private data in the AAC format (<a href="https://www.iso.org/standard/43345.html">AAC specification ISO/IEC 13818-7</a>).</p> </li> </ul> <p>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 <a href="https://tools.ietf.org/html/draft-pantos-http-live-streaming-23">HLS specification</a>.</p> <p>The following procedure shows how to use HLS with Kinesis Video Streams:</p> <ol> <li> <p>Get an endpoint using <a href="http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/API_GetDataEndpoint.html">GetDataEndpoint</a>, specifying <code>GET_HLS_STREAMING_SESSION_URL</code> for the <code>APIName</code> parameter.</p> </li> <li> <p>Retrieve the HLS URL using <code>GetHLSStreamingSessionURL</code>. Kinesis Video Streams creates an HLS streaming session to be used for accessing content in a stream using the HLS protocol. <code>GetHLSStreamingSessionURL</code> returns an authenticated URL (that includes an encrypted session token) for the session's HLS <i>master playlist</i> (the root resource needed for streaming with HLS).</p> <note> <p>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.</p> </note> <p>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.</p> </li> <li> <p>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.</p> </li> <li> <p>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:</p> <ul> <li> <p> <b>GetHLSMasterPlaylist:</b> Retrieves an HLS master playlist, which contains a URL for the <code>GetHLSMediaPlaylist</code> action for each track, and additional metadata for the media player, including estimated bitrate and resolution.</p> </li> <li> <p> <b>GetHLSMediaPlaylist:</b> Retrieves an HLS media playlist, which contains a URL to access the MP4 initialization fragment with the <code>GetMP4InitFragment</code> action, and URLs to access the MP4 media fragments with the <code>GetMP4MediaFragment</code> actions. The HLS media playlist also contains metadata about the stream that the player needs to play it, such as whether the <code>PlaybackMode</code> is <code>LIVE</code> or <code>ON_DEMAND</code>. The HLS media playlist is typically static for sessions with a <code>PlaybackType</code> of <code>ON_DEMAND</code>. The HLS media playlist is continually updated with new fragments for sessions with a <code>PlaybackType</code> of <code>LIVE</code>. 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. </p> </li> <li> <p> <b>GetMP4InitFragment:</b> Retrieves the MP4 initialization fragment. The media player typically loads the initialization fragment before loading any media fragments. This fragment contains the "<code>fytp</code>" and "<code>moov</code>" MP4 atoms, and the child atoms that are needed to initialize the media player decoder.</p> <p>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.</p> </li> <li> <p> <b>GetMP4MediaFragment:</b> Retrieves MP4 media fragments. These fragments contain the "<code>moof</code>" and "<code>mdat</code>" MP4 atoms and their child atoms, containing the encoded fragment's media frames and their timestamps. </p> <note> <p>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.</p> </note> <p>Data retrieved with this action is billable. See <a href="https://aws.amazon.com/kinesis/video-streams/pricing/">Pricing</a> for details.</p> </li> <li> <p> <b>GetTSFragment:</b> Retrieves MPEG TS fragments containing both initialization and media data for all tracks in the stream.</p> <note> <p>If the <code>ContainerFormat</code> is <code>MPEG_TS</code>, this API is used instead of <code>GetMP4InitFragment</code> and <code>GetMP4MediaFragment</code> to retrieve stream media.</p> </note> <p>Data retrieved with this action is billable. For more information, see <a href="https://aws.amazon.com/kinesis/video-streams/pricing/">Kinesis Video Streams pricing</a>.</p> </li> </ul> </li> </ol> <note> <p>The following restrictions apply to HLS sessions:</p> <ul> <li> <p>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 <a href="http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/limits.html">Kinesis Video Streams Limits</a>.</p> </li> <li> <p>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 <code>GetMedia</code> 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 <code>GetMedia</code> connection limit.</p> </li> </ul> </note> <p>You can monitor the amount of data that the media player consumes by monitoring the <code>GetMP4MediaFragment.OutgoingBytes</code> Amazon CloudWatch metric. For information about using CloudWatch to monitor Kinesis Video Streams, see <a href="http://docs.aws.amazon.com/kinesisvideostreams/latest/dg/monitoring.html">Monitoring Kinesis Video Streams</a>.
