Field Detail

FLAG_ALLOW_NON_IDR_KEYFRAMES

public static final int FLAG_ALLOW_NON_IDR_KEYFRAMES

When extracting H.264 samples, whether to treat samples consisting of non-IDR I slices as synchronization samples (key-frames).

Constant Field Values

FLAG_IGNORE_AAC_STREAM

public static final int FLAG_IGNORE_AAC_STREAM

Prevents the creation of AdtsReader and LatmReader instances. This flag should be enabled if the transport stream contains no packets for an AAC elementary stream that is declared in the PMT.

Constant Field Values

FLAG_IGNORE_H264_STREAM

public static final int FLAG_IGNORE_H264_STREAM

Prevents the creation of H264Reader instances. This flag should be enabled if the transport stream contains no packets for an H.264 elementary stream that is declared in the PMT.

See Also:

Constant Field Values

FLAG_DETECT_ACCESS_UNITS

public static final int FLAG_DETECT_ACCESS_UNITS

When extracting H.264 samples, whether to split the input stream into access units (samples) based on slice headers. This flag should be disabled if the stream contains access unit delimiters (AUDs).

Constant Field Values

FLAG_IGNORE_SPLICE_INFO_STREAM

public static final int FLAG_IGNORE_SPLICE_INFO_STREAM

Prevents the creation of SpliceInfoSectionReader instances.

See Also:

Constant Field Values

FLAG_OVERRIDE_CAPTION_DESCRIPTORS

public static final int FLAG_OVERRIDE_CAPTION_DESCRIPTORS

Whether the list of closedCaptionFormats passed to DefaultTsPayloadReaderFactory(int, List) should be used in spite of any closed captions service descriptors. If this flag is disabled, closedCaptionFormats will be ignored if the PMT contains closed captions service descriptors.

Constructor Detail

DefaultTsPayloadReaderFactory

public DefaultTsPayloadReaderFactory()

DefaultTsPayloadReaderFactory

public DefaultTsPayloadReaderFactory(@DefaultTsPayloadReaderFactory.Flags
                                     int flags)

Parameters:

flags - A combination of FLAG_* values that control the behavior of the created readers.

DefaultTsPayloadReaderFactory

public DefaultTsPayloadReaderFactory(@DefaultTsPayloadReaderFactory.Flags
                                     int flags,
                                     java.util.List<Format> closedCaptionFormats)

Parameters:

flags - A combination of FLAG_* values that control the behavior of the created readers.

closedCaptionFormats - Formats to be exposed by payload readers for streams with embedded closed captions when no caption service descriptors are provided. If FLAG_OVERRIDE_CAPTION_DESCRIPTORS is set, closedCaptionFormats overrides any descriptor information. If not set, and closedCaptionFormats is empty, a closed caption track with Format.accessibilityChannel Format.NO_VALUE will be exposed.

Method Detail

createInitialPayloadReaders

public android.util.SparseArray<TsPayloadReader> createInitialPayloadReaders()

Description copied from interface: TsPayloadReader.Factory

Returns the initial mapping from PIDs to payload readers.

This method allows the injection of payload readers for reserved PIDs, excluding PID 0.

Specified by:

createInitialPayloadReaders in interface TsPayloadReader.Factory

Returns:

A SparseArray that maps PIDs to payload readers.

createPayloadReader

public TsPayloadReader createPayloadReader(int streamType,
                                           TsPayloadReader.EsInfo esInfo)

Description copied from interface: TsPayloadReader.Factory

Returns a TsPayloadReader for a given stream type and elementary stream information. May return null if the stream type is not supported.

Specified by:

createPayloadReader in interface TsPayloadReader.Factory

Parameters:

streamType - Stream type value as defined in the PMT entry or associated descriptors.

esInfo - Information associated to the elementary stream provided in the PMT.

Returns:

A TsPayloadReader for the packet stream carried by the provided pid. null if the stream is not supported.
