Constructor Detail

- 

Mp4Extractor

public Mp4Extractor()

Deprecated.

Creates a new extractor for unfragmented MP4 streams.

- 

Mp4Extractor

public Mp4Extractor​(@com.google.android.exoplayer2.extractor.mp4.Mp4Extractor.Flags int flags)

Deprecated.

Creates a new extractor for unfragmented MP4 streams, using the specified flags to control the extractor's behavior. Parameters:flags - Flags that control the extractor's behavior.

Method Detail

- 

sniff

public boolean sniff​([ExtractorInput](../ExtractorInput.html "interface in com.google.android.exoplayer2.extractor")input)
              throws[IOException](https://developer.android.com/reference/java/io/IOException.html "class or interface in java.io")

Deprecated.

Description copied from interface: Extractor

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.

Specified by:sniff in interface ExtractorParameters:input - The ExtractorInput from which data should be peeked/read.Returns:Whether this extractor can read the provided input.Throws:IOException - If an error occurred reading from the input.

- 

init

public void init​([ExtractorOutput](../ExtractorOutput.html "interface in com.google.android.exoplayer2.extractor")output)

Deprecated.

Description copied from interface: Extractor

Initializes the extractor with an ExtractorOutput. Called at most once. Specified by:init in interface ExtractorParameters:output - An ExtractorOutput to receive extracted data.

- 

seek

public void seek​(long position,
                 long timeUs)

Deprecated.

Description copied from interface: Extractor

Notifies the extractor that a seek has occurred.

Following a call to this method, the ExtractorInput passed to the next invocation of Extractor.read(ExtractorInput, PositionHolder) 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.

Specified by:seek in interface ExtractorParameters:position - The byte offset in the stream from which data will be provided.timeUs - The seek time in microseconds.

- 

release

public void release()

Deprecated.

Description copied from interface: Extractor

Releases all kept resources. Specified by:release in interface Extractor

- 

read

public int read​([ExtractorInput](../ExtractorInput.html "interface in com.google.android.exoplayer2.extractor")input,[PositionHolder](../PositionHolder.html "class in com.google.android.exoplayer2.extractor")seekPosition)
         throws[IOException](https://developer.android.com/reference/java/io/IOException.html "class or interface in java.io")

Deprecated.

Description copied from interface: Extractor

Extracts data read from a provided ExtractorInput. Must not be called before Extractor.init(ExtractorOutput).

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, Extractor.RESULT_CONTINUE is returned to indicate that the ExtractorInput 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 Extractor.RESULT_SEEK is returned. If the extractor reached the end of the data provided by the ExtractorInput, then Extractor.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.

Specified by:read in interface ExtractorParameters:input - The ExtractorInput from which data should be read.seekPosition - If Extractor.RESULT_SEEK is returned, this holder is updated to hold the position of the required data.Returns:One of the RESULT_ values defined in this interface.Throws:IOException - If an error occurred reading from or parsing the input.

isSeekable

public boolean isSeekable()

Deprecated.

Description copied from interface: SeekMap

Returns whether seeking is supported. Specified by:isSeekable in interface SeekMapReturns:Whether seeking is supported.

- 

getDurationUs

public long getDurationUs()

Deprecated.

Description copied from interface: SeekMap

Returns the duration of the stream in microseconds. Specified by:getDurationUs in interface SeekMapReturns:The duration of the stream in microseconds, or C.TIME_UNSET if the duration is unknown.

- 

getSeekPoints

public[SeekMap.SeekPoints](../SeekMap.SeekPoints.html "class in com.google.android.exoplayer2.extractor")getSeekPoints​(long timeUs)

Deprecated.

Description copied from interface: SeekMap

Obtains seek points for the specified seek time in microseconds. The returned SeekMap.SeekPoints will contain one or two distinct seek points.

Two seek points [A, B] are returned in the case that seeking can only be performed to discrete points in time, there does not exist a seek point at exactly the requested time, and there exist seek points on both sides of it. In this case A and B are the closest seek points before and after the requested time. A single seek point is returned in all other cases.

Specified by:getSeekPoints in interface SeekMapParameters:timeUs - A seek time in microseconds.Returns:The corresponding seek points.

- 

getSeekPoints

public[SeekMap.SeekPoints](../SeekMap.SeekPoints.html "class in com.google.android.exoplayer2.extractor")getSeekPoints​(long timeUs,
                                        int trackId)

Deprecated.

Equivalent to SeekMap.getSeekPoints(long), except it adds the trackId parameter. Parameters:timeUs - A seek time in microseconds.trackId - The id of the track on which to seek for SeekMap.SeekPoints. May be C.INDEX_UNSET if the extractor is expected to define the strategy for generating SeekMap.SeekPoints.Returns:The corresponding seek points.
