DefaultExtractorsFactory()

Public functions

createExtractors

synchronized fun createExtractors(): Array<Extractor!>!

Returns an array of new Extractor instances.

createExtractors

synchronized 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.

experimentalSetTextTrackTranscodingEnabled

synchronized fun experimentalSetTextTrackTranscodingEnabled(
    textTrackTranscodingEnabled: Boolean
): DefaultExtractorsFactory!

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
DefaultExtractorsFactory!

The factory, for convenience.

setAdtsExtractorFlags

@CanIgnoreReturnValue
synchronized fun setAdtsExtractorFlags(@AdtsExtractor.Flags flags: Int): DefaultExtractorsFactory!

Sets flags for AdtsExtractor instances created by the factory.

Parameters
@AdtsExtractor.Flags flags: Int

The flags to use.

Returns
DefaultExtractorsFactory!

The factory, for convenience.

setAmrExtractorFlags

@CanIgnoreReturnValue
synchronized fun setAmrExtractorFlags(@AmrExtractor.Flags flags: Int): DefaultExtractorsFactory!

Sets flags for AmrExtractor instances created by the factory.

Parameters
@AmrExtractor.Flags flags: Int

The flags to use.

Returns
DefaultExtractorsFactory!

The factory, for convenience.

AmrExtractor

setConstantBitrateSeekingAlwaysEnabled

@CanIgnoreReturnValue
synchronized fun setConstantBitrateSeekingAlwaysEnabled(
    constantBitrateSeekingAlwaysEnabled: Boolean
): DefaultExtractorsFactory!

Convenience method to set whether approximate seeking using constant bitrate assumptions should be enabled for all extractors that support it, and if it should be enabled even if the content length (and hence the duration of the media) is unknown. If set to true, the flags required to enable this functionality will be OR'd with those passed to the setters when creating extractor instances. If set to false then the flags passed to the setters will be used without modification.

When seeking into content where the length is unknown, application code should ensure that requested seek positions are valid, or should be ready to handle playback failures reported through onPlayerError with errorCode set to ERROR_CODE_IO_READ_POSITION_OUT_OF_RANGE.

Parameters
constantBitrateSeekingAlwaysEnabled: Boolean

Whether approximate seeking using a constant bitrate assumption should be enabled for all extractors that support it, including when the content duration is unknown.

Returns
DefaultExtractorsFactory!

The factory, for convenience.

setConstantBitrateSeekingEnabled

@CanIgnoreReturnValue
synchronized fun setConstantBitrateSeekingEnabled(
    constantBitrateSeekingEnabled: Boolean
): DefaultExtractorsFactory!

Convenience method to set whether approximate seeking using constant bitrate assumptions should be enabled for all extractors that support it. If set to true, the flags required to enable this functionality will be OR'd with those passed to the setters when creating extractor instances. If set to false then the flags passed to the setters will be used without modification.

Parameters
constantBitrateSeekingEnabled: Boolean

Whether approximate seeking using a constant bitrate assumption should be enabled for all extractors that support it.

Returns
DefaultExtractorsFactory!

The factory, for convenience.
