Mp4Muxer.Builder

Builder(outputStream: FileOutputStream!)

Creates a Builder instance with default values.

fun build(): Mp4Muxer!

Builds an Mp4Muxer instance.

@CanIgnoreReturnValue
fun setAnnexBToAvccConverter(annexBToAvccConverter: AnnexBToAvccConverter!): Mp4Muxer.Builder!

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.

@CanIgnoreReturnValue
fun setAttemptStreamableOutputEnabled(
    attemptStreamableOutputEnabled: Boolean
): Mp4Muxer.Builder!

Sets whether to attempt to write a file where the metadata is stored at the start, which can make the file more efficient to read sequentially.

Setting to true does not guarantee a streamable MP4 output.

The default value is true.

@CanIgnoreReturnValue
fun setEditableVideoParameters(
    editableVideoParameters: Mp4Muxer.EditableVideoParameters!
): Mp4Muxer.Builder!

Sets the EditableVideoParameters.

@CanIgnoreReturnValue
fun setLastSampleDurationBehavior(
    @Mp4Muxer.LastSampleDurationBehavior lastSampleDurationBehavior: Int
): Mp4Muxer.Builder!

Sets the LastSampleDurationBehavior.

The default value is LAST_SAMPLE_DURATION_BEHAVIOR_SET_FROM_END_OF_STREAM_BUFFER_OR_DUPLICATE_PREVIOUS.

@CanIgnoreReturnValue
fun setOutputFileFormat(@Mp4Muxer.FileFormat fileFormat: Int): Mp4Muxer.Builder!

Sets the specific MP4 file format.

The default value is FILE_FORMAT_DEFAULT.

For FILE_FORMAT_EDITABLE_VIDEO, EditableVideoParameters must also be setEditableVideoParameters set}.

@CanIgnoreReturnValue
fun setSampleCopyEnabled(enabled: Boolean): Mp4Muxer.Builder!

Sets whether to enable the sample copy.

If the sample copy is enabled, writeSampleData copies the input ByteBuffer and BufferInfo before it returns, so it is safe to reuse them immediately. Otherwise, the muxer takes ownership of the and the BufferInfo and the caller must not modify them.

The default value is true.
