Array<Extractor!>!
createExtractors(
    uri: Uri!,
    responseHeaders: (Mutable)Map<String!, (Mutable)List<String!>!>!
)

Returns an array of new Extractor instances.
ExtractorsFactory!
experimentalSetCodecsToParseWithinGopSampleDependencies(
    @C.VideoCodecFlags codecsToParseWithinGopSampleDependencies: Int
)

Sets the set of video codecs for which within GOP sample dependency information should be parsed as part of extraction.
ExtractorsFactory!
experimentalSetTextTrackTranscodingEnabled(
    textTrackTranscodingEnabled: Boolean
)

This function is deprecated.

This method (and all support for 'legacy' subtitle decoding during rendering) will be removed in a future release.
ExtractorsFactory!

Sets a SubtitleParser.Factory to use when transcoding text tracks.

Inherited Constants

Public constructors

ForwardingExtractorsFactory

ForwardingExtractorsFactory(factory: ExtractorsFactory!)

Creates a forwarding ExtractorsFactory.

Parameters
factory: ExtractorsFactory!

The ExtractorsFactory to forward to.

Public functions

createExtractors

fun createExtractors(): Array<Extractor!>!

Returns an array of new Extractor instances.

createExtractors

fun createExtractors(
    uri: Uri!,
    responseHeaders: (Mutable)Map<String!, (Mutable)List<String!>!>!
): Array<Extractor!>!

Returns an array of new Extractor instances.

Parameters
uri: Uri!

The Uri of the media to extract.
responseHeaders: (Mutable)Map<String!, (Mutable)List<String!>!>!

The response headers of the media to extract, or an empty map if there are none. The map lookup should be case-insensitive.
Returns
Array<Extractor!>!

The Extractor instances.

experimentalSetCodecsToParseWithinGopSampleDependencies

fun experimentalSetCodecsToParseWithinGopSampleDependencies(
    @C.VideoCodecFlags codecsToParseWithinGopSampleDependencies: Int
): ExtractorsFactory!

Sets the set of video codecs for which within GOP sample dependency information should be parsed as part of extraction. Defaults to H.264 and H.265.

Having access to additional sample dependency information can speed up seeking. See FLAG_READ_WITHIN_GOP_SAMPLE_DEPENDENCIES.

This method is experimental and will be renamed or removed in a future release.

Parameters
@C.VideoCodecFlags codecsToParseWithinGopSampleDependencies: Int

The set of codecs for which to parse within GOP sample dependency information.
Returns
ExtractorsFactory!

This factory, for convenience.

experimentalSetTextTrackTranscodingEnabled

fun experimentalSetTextTrackTranscodingEnabled(
    textTrackTranscodingEnabled: Boolean
): ExtractorsFactory!

Enables transcoding of text track samples to APPLICATION_MEDIA3_CUES before the data is emitted to TrackOutput.

Transcoding is enabled by default.

This method is experimental and will be renamed or removed in a future release.

Parameters
textTrackTranscodingEnabled: Boolean

Whether to enable transcoding.
Returns
ExtractorsFactory!

The factory, for convenience.

setSubtitleParserFactory

fun setSubtitleParserFactory(subtitleParserFactory: SubtitleParser.Factory!): ExtractorsFactory!

Sets a SubtitleParser.Factory to use when transcoding text tracks.

This is only works if experimentalSetTextTrackTranscodingEnabled is enabled.

Parameters
subtitleParserFactory: SubtitleParser.Factory!

The factory for SubtitleParser instances.
Returns
ExtractorsFactory!

The factory, for convenience.
