packageSegment(mp4Generatornon-null, stream, referencenullable) → {shaka.extern.TransmuxerOutput}

Packages the init and media segments produced by the given Mp4Generator. The init segment is cached per discontinuity and the running frame index is advanced. The init segment is only (re)appended when it differs from the last one used.
Parameters:
Name Type Attributes Description
mp4Generator shaka.util.Mp4Generator
stream shaka.extern.Stream
reference shaka.media.SegmentReference <nullable>

Returns:
Type
shaka.extern.TransmuxerOutput

transmux(data, stream, referencenullable, duration, contentType) → {Promise<(!Uint8Array|!shaka.extern.TransmuxerOutput)>}

Transmux a input data to MP4.
Parameters:
Name Type Attributes Description
data BufferSource
stream shaka.extern.Stream
reference shaka.media.SegmentReference <nullable>
 The segment reference, or null for init segments
duration number
contentType string

Returns:
If you only want to return the result, use Uint8Array, if you want to separate the initialization segment and the data segment, you have to use shaka.extern.TransmuxerOutput
Type
Promise<(!Uint8Array|!shaka.extern.TransmuxerOutput)>
