HlsMediaChunkExtractor

fun init(extractorOutput: ExtractorOutput!): Unit

Initializes the extractor with an ExtractorOutput. Called at most once.

fun isPackedAudioExtractor(): Boolean

Returns whether this is a packed audio extractor, as defined in RFC 8216, Section 3.4.

fun isReusable(): Boolean

Returns whether this instance can be used for extracting multiple continuous segments.

fun onTruncatedSegmentParsed(): Unit

Resets the sample parsing state.

Resetting the parsing state allows support for Fragmented MP4 EXT-X-I-FRAME-STREAM-INF segments. EXT-X-I-FRAME-STREAM-INF segments are truncated to include only a leading key frame. After parsing said keyframe, an extractor may reach an unexpected end of file. By resetting its state, we can continue feeding samples from the following segments to the extractor. See #7512 for context.

fun read(extractorInput: ExtractorInput!): Boolean

Extracts data read from a provided ExtractorInput. Must not be called before init.

A single call to this method will block until some progress has been made, but will not block for longer than this. Hence each call will consume only a small amount of input data.

When this method throws an IOException, extraction may continue by providing an ExtractorInput with an unchanged read position to a subsequent call to this method.

fun recreate(): HlsMediaChunkExtractor!

Returns a new instance for extracting the same type of media as this one. Can only be called on instances that are not reusable.
