Public constructors

Factory

public Factory()

Creates an instance with default values.

Factory

public Factory(@Nullable InAppMp4Muxer.MetadataProvider metadataProvider)

Creates an instance.

Parameters
`@Nullable InAppMp4Muxer.MetadataProvider metadataProvider`	A `MetadataProvider`.

Public methods

create

public InAppMp4Muxer create(String path)

Returns a new Muxer.

Parameters
`String path`	The path to the output file.

Throws
`androidx.media3.muxer.MuxerException`	If an error occurs opening the output file for writing.

getSupportedSampleMimeTypes

public ImmutableList<String> getSupportedSampleMimeTypes(@C.TrackType int trackType)

Returns the supported sample MIME types for the given C.TrackType.

setVideoDurationUs

@CanIgnoreReturnValue
public InAppMp4Muxer.Factory setVideoDurationUs(long videoDurationUs)

Sets the duration of the video track (in microseconds) in the output.

Only the duration of the last sample is adjusted to achieve the given duration. Duration of the other samples remains unchanged.

The default is TIME_UNSET to not set any duration in the output. In this case the video track duration is determined by the samples written to it and the duration of the last sample will be same as that of the sample before that.

Parameters
`long videoDurationUs`	The duration of the video track (in microseconds) in the output, or `TIME_UNSET` to not set any duration. Only applicable when a video track is `added`.

Returns
`InAppMp4Muxer.Factory`	This factory.

supportsWritingNegativeTimestampsInEditList

public boolean supportsWritingNegativeTimestampsInEditList()

Whether the muxer supports writing negative timestamps into an edit list to instruct players to ignore these samples.
