Summary

Public constructors

Creates a forwarding ExtractorsFactory.

Public functions
Array<Extractor!>!

Returns an array of new Extractor instances.
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

const ExtractorsFactory!

Extractor factory that returns an empty list of extractors.

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 0 - empty set of codecs.

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.
