Muxer implementation that uses a Mp4Muxer.

Summary

Nested types
`class InAppMuxer.Factory : Muxer.Factory` `Muxer.Factory` for `InAppMuxer`.
`class InAppMuxer.Factory.Builder` A builder for `Factory` instances.
`interface InAppMuxer.MetadataProvider` Provides `metadata` to add in the output MP4 file.

Public functions
`Unit`	`addMetadata(metadata: Metadata!)` Adds `Metadata` about the output file.
`Int`	`addTrack(format: Format!)` Adds a track with the specified format.
`Unit`	`release(forCancellation: Boolean)` Finishes writing the output and releases any resources associated with muxing.
`Unit`	`writeSampleData( trackIndex: Int, data: ByteBuffer!, presentationTimeUs: Long, @C.BufferFlags flags: Int )` Writes the specified sample.

Public properties
`Long`	`maxDelayBetweenSamplesMs`

fun addMetadata(metadata: Metadata!): Unit

Adds Metadata about the output file.

fun addTrack(format: Format!): Int

Adds a track with the specified format.

Parameters
`format: Format!`	The `Format` of the track.

Returns
`Int`	The index for this track, which should be passed to `writeSampleData`.

Throws
`androidx.media3.transformer.Muxer.MuxerException`	If the muxer encounters a problem while adding the track.

fun release(forCancellation: Boolean): Unit

Finishes writing the output and releases any resources associated with muxing.

The muxer cannot be used anymore once this method has been called.

Parameters
`forCancellation: Boolean`	Whether the reason for releasing the resources is the export cancellation.

Throws
`androidx.media3.transformer.Muxer.MuxerException`	If the muxer fails to finish writing the output and `forCancellation` is false.

fun writeSampleData(
    trackIndex: Int,
    data: ByteBuffer!,
    presentationTimeUs: Long,
    @C.BufferFlags flags: Int
): Unit

Writes the specified sample.

Parameters
`trackIndex: Int`	The index of the track, previously returned by `addTrack`.
`data: ByteBuffer!`	A buffer containing the sample data to write to the container.
`presentationTimeUs: Long`	The presentation time of the sample in microseconds.
`@C.BufferFlags flags: Int`	The `C.BufferFlags` associated with the data. Only `BUFFER_FLAG_KEY_FRAME` and `BUFFER_FLAG_END_OF_STREAM` are supported.

Throws
`androidx.media3.transformer.Muxer.MuxerException`	If the muxer fails to write the sample.
