MediaSink

An open output file (muxer). Add every encoder first, video and audio, because the muxer's header freezes the stream list. Then push frames through the encoders. Close the sink to write the trailer and flush buffers.

Functions

addAudioEncoder

expect fun addAudioEncoder(spec: AudioEncoderSpec): AudioEncoder

Add an audio encoder. Must be called before any frame is written.

actual fun addAudioEncoder(spec: AudioEncoderSpec): AudioEncoder

Add an audio encoder. Must be called before any frame is written.

actual fun addAudioEncoder(spec: AudioEncoderSpec): AudioEncoder

Add an audio encoder. Must be called before any frame is written.

actual fun addAudioEncoder(spec: AudioEncoderSpec): AudioEncoder

Add an audio encoder. Must be called before any frame is written.

addCopyStream

expect fun addCopyStream(source: MediaSource, stream: StreamInfo): CopyStream

Add an output stream that copies stream's packets verbatim from source: no decode, no re-encode, only timestamp rescaling into the output's time-base (ffmpeg -c copy). Bitstream filters are not applied, so format pairs that need one (e.g. h264 in mp4 → MPEG-TS Annex B) are not yet supported.

actual fun addCopyStream(source: MediaSource, stream: StreamInfo): CopyStream

addVideoEncoder

expect fun addVideoEncoder(spec: VideoEncoderSpec): VideoEncoder

Add a video encoder. Must be called before any frame is written.

actual fun addVideoEncoder(spec: VideoEncoderSpec): VideoEncoder

Add a video encoder. Must be called before any frame is written.

actual fun addVideoEncoder(spec: VideoEncoderSpec): VideoEncoder

Add a video encoder. Must be called before any frame is written.

actual fun addVideoEncoder(spec: VideoEncoderSpec): VideoEncoder

Add a video encoder. Must be called before any frame is written.

expect open override fun close()

Flushes every encoder, writes the trailer, and frees the muxer.

actual open override fun close()

Flushes every encoder, writes the trailer, and frees the muxer.

actual open override fun close()

Flushes every encoder, writes the trailer, and frees the muxer.

actual open override fun close()

Flushes every encoder, writes the trailer, and frees the muxer.

setMetadata

expect fun setMetadata(metadata: Map<String, String>)

Container-level metadata tags (title, artist, comment, …). Call this before any frame or packet is written, because the tags are stored in the header.
