Mp4Muxer.Builder

Kotlin |Java

public final class Mp4Muxer.Builder

A builder for Mp4Muxer instances.

Summary

Public constructors
`Builder(FileOutputStream fileOutputStream)` Creates a `Builder` instance with default values.

Public methods
`Mp4Muxer`	`build()` Builds an `Mp4Muxer` instance.
`Mp4Muxer.Builder`	`@CanIgnoreReturnValue setAnnexBToAvccConverter(AnnexBToAvccConverter annexBToAvccConverter)` Sets the `AnnexBToAvccConverter` to be used by the muxer to convert H.264 and H.265 NAL units from the Annex-B format (using start codes to delineate NAL units) to the AVCC format (which uses length prefixes).
`Mp4Muxer.Builder`	`@CanIgnoreReturnValue setFragmentDurationUs(int fragmentDurationUs)` Sets fragment duration for the `fragmented MP4`.
`Mp4Muxer.Builder`	`@CanIgnoreReturnValue setFragmentedMp4Enabled(boolean enabled)` Sets whether to enable writing a fragmented MP4.
`Mp4Muxer.Builder`	`@CanIgnoreReturnValue setLastFrameDurationBehavior( @Mp4Muxer.LastFrameDurationBehavior int lastFrameDurationBehavior )` Sets the `LastFrameDurationBehavior` for the video track.

Public constructors

Builder

public Builder(FileOutputStream fileOutputStream)

Creates a Builder instance with default values.

Parameters
`FileOutputStream fileOutputStream`	The `FileOutputStream` to write the media data to.

Public methods

build

public Mp4Muxer build()

Builds an Mp4Muxer instance.

setAnnexBToAvccConverter

@CanIgnoreReturnValue
public Mp4Muxer.Builder setAnnexBToAvccConverter(AnnexBToAvccConverter annexBToAvccConverter)

Sets the AnnexBToAvccConverter to be used by the muxer to convert H.264 and H.265 NAL units from the Annex-B format (using start codes to delineate NAL units) to the AVCC format (which uses length prefixes).

The default value is DEFAULT.

setFragmentDurationUs

@CanIgnoreReturnValue
public Mp4Muxer.Builder setFragmentDurationUs(int fragmentDurationUs)

Sets fragment duration for the fragmented MP4.

Muxer will attempt to create fragments of the given duration but the actual duration might be greater depending upon the frequency of sync samples.

The duration is ignored for non fragmented MP4.

The default value is DEFAULT_FRAGMENT_DURATION_US.

Parameters
`int fragmentDurationUs`	The fragment duration in microseconds.

Returns
`Mp4Muxer.Builder`	The `Mp4Muxer.Builder`.

setFragmentedMp4Enabled

@CanIgnoreReturnValue
public Mp4Muxer.Builder setFragmentedMp4Enabled(boolean enabled)

Sets whether to enable writing a fragmented MP4.

The default value is false.

setLastFrameDurationBehavior

@CanIgnoreReturnValue
public Mp4Muxer.Builder setLastFrameDurationBehavior(
    @Mp4Muxer.LastFrameDurationBehavior int lastFrameDurationBehavior
)

Sets the LastFrameDurationBehavior for the video track.

The default value is LAST_FRAME_DURATION_BEHAVIOR_INSERT_SHORT_FRAME.
