Amazonka.KinesisVideoMedia.Types.StartSelector

Description

Documentation

data StartSelector Source #

Identifies the chunk on the Kinesis video stream where you want the GetMedia API to start returning media data. You have the following options to identify the starting chunk:

Choose the latest (or oldest) chunk.
Identify a specific chunk. You can identify a specific chunk either by providing a fragment number or timestamp (server or producer).
Each chunk's metadata includes a continuation token as a Matroska (MKV) tag (AWS_KINESISVIDEO_CONTINUATION_TOKEN). If your previous GetMedia request terminated, you can use this tag value in your next GetMedia request. The API then starts returning chunks starting where the last API ended.

See: newStartSelector smart constructor.

StartSelector'

Fields

continuationToken :: Maybe Text
Continuation token that Kinesis Video Streams returned in the previous GetMedia response. The GetMedia API then starts with the chunk identified by the continuation token.
afterFragmentNumber :: Maybe Text
Specifies the fragment number from where you want the GetMedia API to start returning the fragments.
startTimestamp :: Maybe POSIX
A timestamp value. This value is required if you choose the PRODUCER_TIMESTAMP or the SERVER_TIMESTAMP as the startSelectorType. The GetMedia API then starts with the chunk containing the fragment that has the specified timestamp.
startSelectorType :: StartSelectorType
Identifies the fragment on the Kinesis video stream where you want to start getting the data from.
- NOW - Start with the latest chunk on the stream.
- EARLIEST - Start with earliest available chunk on the stream.
- FRAGMENT_NUMBER - Start with the chunk after a specific fragment. You must also specify the AfterFragmentNumber parameter.
- PRODUCER_TIMESTAMP or SERVER_TIMESTAMP - Start with the chunk containing a fragment with the specified producer or server timestamp. You specify the timestamp by adding StartTimestamp.
- CONTINUATION_TOKEN - Read using the specified continuation token.
If you choose the NOW, EARLIEST, or CONTINUATION_TOKEN as the startSelectorType, you don't provide any additional information in the startSelector.

Arguments

:: StartSelectorType	`$sel:startSelectorType:StartSelector'`
-> StartSelector

Create a value of StartSelector with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:continuationToken:StartSelector', startSelector_continuationToken - Continuation token that Kinesis Video Streams returned in the previous GetMedia response. The GetMedia API then starts with the chunk identified by the continuation token.

$sel:afterFragmentNumber:StartSelector', startSelector_afterFragmentNumber - Specifies the fragment number from where you want the GetMedia API to start returning the fragments.

$sel:startTimestamp:StartSelector', startSelector_startTimestamp - A timestamp value. This value is required if you choose the PRODUCER_TIMESTAMP or the SERVER_TIMESTAMP as the startSelectorType. The GetMedia API then starts with the chunk containing the fragment that has the specified timestamp.

$sel:startSelectorType:StartSelector', startSelector_startSelectorType - Identifies the fragment on the Kinesis video stream where you want to start getting the data from.

NOW - Start with the latest chunk on the stream.
EARLIEST - Start with earliest available chunk on the stream.
FRAGMENT_NUMBER - Start with the chunk after a specific fragment. You must also specify the AfterFragmentNumber parameter.
PRODUCER_TIMESTAMP or SERVER_TIMESTAMP - Start with the chunk containing a fragment with the specified producer or server timestamp. You specify the timestamp by adding StartTimestamp.
CONTINUATION_TOKEN - Read using the specified continuation token.

If you choose the NOW, EARLIEST, or CONTINUATION_TOKEN as the startSelectorType, you don't provide any additional information in the startSelector.

startSelector_continuationToken :: Lens' StartSelector (Maybe Text) Source #

Continuation token that Kinesis Video Streams returned in the previous GetMedia response. The GetMedia API then starts with the chunk identified by the continuation token.

startSelector_afterFragmentNumber :: Lens' StartSelector (Maybe Text) Source #

Specifies the fragment number from where you want the GetMedia API to start returning the fragments.

startSelector_startTimestamp :: Lens' StartSelector (Maybe UTCTime) Source #

A timestamp value. This value is required if you choose the PRODUCER_TIMESTAMP or the SERVER_TIMESTAMP as the startSelectorType. The GetMedia API then starts with the chunk containing the fragment that has the specified timestamp.

startSelector_startSelectorType :: Lens' StartSelector StartSelectorType Source #

Identifies the fragment on the Kinesis video stream where you want to start getting the data from.

NOW - Start with the latest chunk on the stream.
EARLIEST - Start with earliest available chunk on the stream.
FRAGMENT_NUMBER - Start with the chunk after a specific fragment. You must also specify the AfterFragmentNumber parameter.
PRODUCER_TIMESTAMP or SERVER_TIMESTAMP - Start with the chunk containing a fragment with the specified producer or server timestamp. You specify the timestamp by adding StartTimestamp.
CONTINUATION_TOKEN - Read using the specified continuation token.

If you choose the NOW, EARLIEST, or CONTINUATION_TOKEN as the startSelectorType, you don't provide any additional information in the startSelector.
