Constructor Detail

DashWrappingSegmentIndex

public DashWrappingSegmentIndex([ChunkIndex](../../extractor/ChunkIndex.html "class in com.google.android.exoplayer2.extractor")chunkIndex,
                                long timeOffsetUs)

Deprecated. Parameters:chunkIndex - The ChunkIndex to wrap.timeOffsetUs - An offset to subtract from the times in the wrapped index, in microseconds.

Method Detail

getFirstSegmentNum

public long getFirstSegmentNum()

Deprecated.

Description copied from interface: DashSegmentIndex

Returns the segment number of the first defined segment in the index. Specified by:getFirstSegmentNum in interface DashSegmentIndex

getFirstAvailableSegmentNum

public long getFirstAvailableSegmentNum(long periodDurationUs,
                                        long nowUnixTimeUs)

Deprecated.

Description copied from interface: DashSegmentIndex

Returns the segment number of the first available segment in the index. Specified by:getFirstAvailableSegmentNum in interface DashSegmentIndexParameters:periodDurationUs - The duration of the enclosing period in microseconds, or C.TIME_UNSET if the period's duration is not yet known.nowUnixTimeUs - The current time in milliseconds since the Unix epoch.Returns:The number of the first available segment.

getSegmentCount

public long getSegmentCount(long periodDurationUs)

Deprecated.

Description copied from interface: DashSegmentIndex

Returns the number of segments defined in the index, or DashSegmentIndex.INDEX_UNBOUNDED.

An unbounded index occurs if a dynamic manifest uses SegmentTemplate elements without a SegmentTimeline element, and if the period duration is not yet known. In this case the caller can query the available segment using DashSegmentIndex.getFirstAvailableSegmentNum(long, long) and DashSegmentIndex.getAvailableSegmentCount(long, long).

Specified by:getSegmentCount in interface DashSegmentIndexParameters:periodDurationUs - The duration of the enclosing period in microseconds, or C.TIME_UNSET if the period's duration is not yet known.Returns:The number of segments in the index, or DashSegmentIndex.INDEX_UNBOUNDED.

getAvailableSegmentCount

public long getAvailableSegmentCount(long periodDurationUs,
                                     long nowUnixTimeUs)

Deprecated.

Description copied from interface: DashSegmentIndex

Returns the number of available segments in the index. Specified by:getAvailableSegmentCount in interface DashSegmentIndexParameters:periodDurationUs - The duration of the enclosing period in microseconds, or C.TIME_UNSET if the period's duration is not yet known.nowUnixTimeUs - The current time in milliseconds since the Unix epoch.Returns:The number of available segments in the index.

getNextSegmentAvailableTimeUs

public long getNextSegmentAvailableTimeUs(long periodDurationUs,
                                          long nowUnixTimeUs)

Deprecated.

Description copied from interface: DashSegmentIndex

Returns the time, in microseconds, at which a new segment becomes available, or C.TIME_UNSET if not applicable. Specified by:getNextSegmentAvailableTimeUs in interface DashSegmentIndexParameters:periodDurationUs - The duration of the enclosing period in microseconds, or C.TIME_UNSET if the period's duration is not yet known.nowUnixTimeUs - The current time in milliseconds since the Unix epoch.Returns:The time, in microseconds, at which a new segment becomes available, or C.TIME_UNSET if not applicable.

getTimeUs

public long getTimeUs(long segmentNum)

Deprecated.

Description copied from interface: DashSegmentIndex

Returns the start time of a segment. Specified by:getTimeUs in interface DashSegmentIndexParameters:segmentNum - The segment number.Returns:The corresponding start time in microseconds.

getDurationUs

public long getDurationUs(long segmentNum,
                          long periodDurationUs)

Deprecated.

Description copied from interface: DashSegmentIndex

Returns the duration of a segment. Specified by:getDurationUs in interface DashSegmentIndexParameters:segmentNum - The segment number.periodDurationUs - The duration of the enclosing period in microseconds, or C.TIME_UNSET if the period's duration is not yet known.Returns:The duration of the segment, in microseconds.

getSegmentUrl

public[RangedUri](manifest/RangedUri.html "class in com.google.android.exoplayer2.source.dash.manifest")getSegmentUrl(long segmentNum)

Deprecated.

Description copied from interface: DashSegmentIndex

Returns a RangedUri defining the location of a segment. Specified by:getSegmentUrl in interface DashSegmentIndexParameters:segmentNum - The segment number.Returns:The RangedUri defining the location of the data.

getSegmentNum

public long getSegmentNum(long timeUs,
                          long periodDurationUs)

Deprecated.

Description copied from interface: DashSegmentIndex

Returns getFirstSegmentNum() if the index has no segments or if the given media time is earlier than the start of the first segment. Returns getFirstSegmentNum() + getSegmentCount() - 1 if the given media time is later than the end of the last segment. Otherwise, returns the segment number of the segment containing the given media time. Specified by:getSegmentNum in interface DashSegmentIndexParameters:timeUs - The time in microseconds.periodDurationUs - The duration of the enclosing period in microseconds, or C.TIME_UNSET if the period's duration is not yet known.Returns:The segment number of the corresponding segment.

isExplicit

public boolean isExplicit()

Deprecated.

Description copied from interface: DashSegmentIndex

Returns true if segments are defined explicitly by the index.

If true is returned, each segment is defined explicitly by the index data, and all of the listed segments are guaranteed to be available at the time when the index was obtained.

If false is returned then segment information was derived from properties such as a fixed segment duration. If the presentation is dynamic, it's possible that only a subset of the segments are available.

Specified by:isExplicit in interface DashSegmentIndexReturns:Whether segments are defined explicitly by the index.
