Public constructors

Factory

Factory()

Creates an instance with default values.

Factory

Factory(metadataProvider: InAppMp4Muxer.MetadataProvider?)

Creates an instance.

Parameters
`metadataProvider: InAppMp4Muxer.MetadataProvider?`	A `MetadataProvider`.

Public functions

create

fun create(path: String!): InAppMp4Muxer!

Returns a new Muxer.

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

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

getSupportedSampleMimeTypes

fun getSupportedSampleMimeTypes(@C.TrackType trackType: Int): ImmutableList<String!>!

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

setVideoDurationUs

@CanIgnoreReturnValue
fun setVideoDurationUs(videoDurationUs: Long): InAppMp4Muxer.Factory!

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
`videoDurationUs: Long`	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

fun supportsWritingNegativeTimestampsInEditList(): Boolean

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