AdtsExtractor

const val FACTORY: ExtractorsFactory!

Factory for AdtsExtractor instances.

const val FLAG_ENABLE_CONSTANT_BITRATE_SEEKING = 1: Int

Flag to force enable seeking using a constant bitrate assumption in cases where seeking would otherwise not be possible.

Note that this approach may result in approximated stream duration and seek position that are not precise, especially when the stream bitrate varies a lot.

const val FLAG_ENABLE_CONSTANT_BITRATE_SEEKING_ALWAYS = 2: Int

Like FLAG_ENABLE_CONSTANT_BITRATE_SEEKING, except that seeking is also enabled in cases where the content length (and hence the duration of the media) is unknown. Application code should ensure that requested seek positions are valid when using this flag, or be ready to handle playback failures reported through onPlayerError with errorCode set to ERROR_CODE_IO_READ_POSITION_OUT_OF_RANGE.

If this flag is set, then the behavior enabled by FLAG_ENABLE_CONSTANT_BITRATE_SEEKING is implicitly enabled as well.

AdtsExtractor()

Creates a new extractor for ADTS bitstreams.

AdtsExtractor(@AdtsExtractor.Flags flags: Int)

Creates a new extractor for ADTS bitstreams.

fun init(output: ExtractorOutput!): Unit

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

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.
