Deprecated. com.google.android.exoplayer2 is deprecated. Please migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.

A SeekMap implementation that assumes the stream has a constant bitrate and consists of multiple independent frames of the same size. Seek points are calculated to be at frame boundaries.

ConstantBitrateSeekMap

public ConstantBitrateSeekMap​(long inputLength,
                              long firstFrameBytePosition,
                              int bitrate,
                              int frameSize)

Deprecated.

Creates an instance with allowSeeksIfLengthUnknown set to false. Parameters:inputLength - The length of the stream in bytes, or C.LENGTH_UNSET if unknown.firstFrameBytePosition - The byte-position of the first frame in the stream.bitrate - The bitrate (which is assumed to be constant in the stream).frameSize - The size of each frame in the stream in bytes. May be C.LENGTH_UNSET if unknown.

Method Detail

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.

-

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.

-

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.

-

getTimeUsAtPosition

public long getTimeUsAtPosition​(long position)

Deprecated.

Returns the stream time in microseconds for a given position. Parameters:position - The stream byte-position.Returns:The stream time in microseconds for the given position.
