MediaMuxerCompat

const val OUTPUT_FORMAT_MP4 = 0: Int

The MP4 file format.

MediaMuxerCompat(
    fileDescriptor: FileDescriptor!,
    @MediaMuxerCompat.OutputFormat outputFormat: Int
)

Creates an instance.

It is the caller's responsibility to close the fileDescriptor, which is safe to do so as soon as this call returns.

MediaMuxerCompat(
    filePath: String!,
    @MediaMuxerCompat.OutputFormat outputFormat: Int
)

Creates an instance.

fun addTrack(format: MediaFormat!): Int

Adds a track of the given media format.

All tracks must be added before any samples are written to any track.

KEY_CAPTURE_RATE is used to write KEY_ANDROID_CAPTURE_FPS metadata in the MP4 file.

fun release(): Unit

Releases the underlying resources.

It should be called after stop.

fun setLocation(
    latitude: @FloatRange(from = "-90.0", to = 90.0) Float,
    longitude: @FloatRange(from = "-180.0", to = 180.0) Float
): Unit

Sets the location of the media file.

It must be called before start.

fun setOrientationHint(degrees: Int): Unit

Sets the orientation hint for the media file.

It must be called before start.

fun start(): Unit

Starts the muxer.

This must be called after addTrack and before writeSampleData.

fun stop(): Unit

Stops the muxer.

Once the muxer is stopped, it can not be restarted.

fun writeSampleData(
    trackIndex: Int,
    byteBuffer: ByteBuffer!,
    bufferInfo: MediaCodec.BufferInfo!
): Unit

Writes encoded sample data.

To set the duration of the last sample in a track, an additional empty buffer ( bufferInfo.size = 0) with BUFFER_FLAG_END_OF_STREAM flag and a suitable presentation timestamp must be passed as the last sample of that track. This timestamp should be the sum of the desired duration and the presentation timestamp of the original last sample. If no explicit END_OF_STREAM sample is provided, the last sample's duration will be equal to the previous sample's duration.
