FragmentedMp4Extractor

const val FACTORY: ExtractorsFactory!

const val FLAG_EMIT_RAW_SUBTITLE_DATA = 32: Int

Flag to use the source subtitle formats without modification. If unset, subtitles will be transcoded to APPLICATION_MEDIA3_CUES during extraction.

const val FLAG_ENABLE_EMSG_TRACK = 4: Int

Flag to indicate that the extractor should output an event message metadata track. Any event messages in the stream will be delivered as samples to this track.

const val FLAG_WORKAROUND_EVERY_VIDEO_FRAME_IS_SYNC_FRAME = 1: Int

Flag to work around an issue in some video streams where every frame is marked as a sync frame. The workaround overrides the sync frame flags in the stream, forcing them to false except for the first sample in each segment.

This flag does nothing if the stream is not a video stream.

const val FLAG_WORKAROUND_IGNORE_EDIT_LISTS = 16: Int

Flag to ignore any edit lists in the stream.

const val FLAG_WORKAROUND_IGNORE_TFDT_BOX = 2: Int

Flag to ignore any tfdt boxes in the stream.

fun init(output: ExtractorOutput!): Unit

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

java-static fun newFactory(subtitleParserFactory: SubtitleParser.Factory!): ExtractorsFactory!

Creates a factory for FragmentedMp4Extractor instances with the provided .

fun read(input: ExtractorInput!, seekPosition: PositionHolder!): Int

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.

In the common case, RESULT_CONTINUE is returned to indicate that the passed to the next read is required to provide data continuing from the position in the stream reached by the returning call. If the extractor requires data to be provided from a different position, then that position is set in seekPosition and RESULT_SEEK is returned. If the extractor reached the end of the data provided by the ExtractorInput, then RESULT_END_OF_INPUT is returned.

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 release(): Unit

Releases all kept resources.

fun seek(position: Long, timeUs: Long): Unit

Notifies the extractor that a seek has occurred.

Following a call to this method, the ExtractorInput passed to the next invocation of read is required to provide data starting from position in the stream. Valid random access positions are the start of the stream and positions that can be obtained from any SeekMap passed to the ExtractorOutput.

fun sniff(input: ExtractorInput!): Boolean

Returns whether this extractor can extract samples from the ExtractorInput, which must provide data from the start of the stream.

If true is returned, the input's reading position may have been modified. Otherwise, only its peek position may have been modified.
