DefaultExtractorsFactory
@UnstableApi
public final class DefaultExtractorsFactory implements ExtractorsFactory
An ExtractorsFactory that provides an array of extractors for the following formats:
- MP4, including M4A (
Mp4Extractor) - fMP4 (
FragmentedMp4Extractor) - Matroska and WebM (
MatroskaExtractor) - Ogg Vorbis/FLAC (
OggExtractor - MP3 (
Mp3Extractor) - AAC (
AdtsExtractor) - MPEG TS (
TsExtractor) - MPEG PS (
PsExtractor) - FLV (
FlvExtractor) - WAV (
WavExtractor) - AC3 (
Ac3Extractor) - AC4 (
Ac4Extractor) - AMR (
AmrExtractor) - FLAC
- If available, the FLAC extension's
androidx.media3.decoder.flac.FlacExtractoris used. - Otherwise, the core
FlacExtractoris used. Note that Android devices do not generally include a FLAC decoder before API 27. This can be worked around by using the FLAC extension or the FFmpeg extension.
- If available, the FLAC extension's
- JPEG (
JpegExtractor) - PNG (
PngExtractor) - WEBP (
WebpExtractor) - BMP (
BmpExtractor) - HEIF (
HeifExtractor) - AVIF (
AvifExtractor) - MIDI, if available, the MIDI extension's
androidx.media3.decoder.midi.MidiExtractoris used.

experimentalSetTextTrackTranscodingEnabled
synchronized public DefaultExtractorsFactoryexperimentalSetTextTrackTranscodingEnabled(
boolean textTrackTranscodingEnabled
)
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 | |
|---|---|
boolean textTrackTranscodingEnabled |
Whether to enable transcoding. |
| Returns | |
|---|---|
DefaultExtractorsFactory |
The factory, for convenience. |

Sets flags for AdtsExtractor instances created by the factory.
| Parameters | |
|---|---|
@AdtsExtractor.Flags int flags |
The flags to use. |
| Returns | |
|---|---|

setAmrExtractorFlags
@CanIgnoreReturnValue
synchronized public DefaultExtractorsFactory setAmrExtractorFlags(@AmrExtractor.Flags int flags)
Sets flags for AmrExtractor instances created by the factory.
| Parameters | |
|---|---|
@AmrExtractor.Flags int flags |

setConstantBitrateSeekingAlwaysEnabled
@CanIgnoreReturnValue
synchronized public DefaultExtractorsFactory setConstantBitrateSeekingAlwaysEnabled(
boolean constantBitrateSeekingAlwaysEnabled
)
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 | |
|---|---|
boolean constantBitrateSeekingAlwaysEnabled |
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. |

If set to false then the flags passed to the setters will be used without modification.
| Parameters | |
