Summary

Public functions
`Codec!`	`createForAudioDecoding(format: Format!, logSessionId: LogSessionId?)` Returns a `Codec` for audio decoding.
`Codec!`	`createForVideoDecoding( format: Format!, outputSurface: Surface!, requestSdrToneMapping: Boolean, logSessionId: LogSessionId? )` Returns a `Codec` for video decoding.

Public functions

createForAudioDecoding

fun createForAudioDecoding(format: Format!, logSessionId: LogSessionId?): Codec!

Returns a Codec for audio decoding.

Parameters
`format: Format!`	The `Format` (of the input data) used to determine the underlying decoder and its configuration values.
`logSessionId: LogSessionId?`	The optional `LogSessionId` of the `android.media.metrics.EditingSession`.

Returns
`Codec!`	A `Codec` for audio decoding.

Throws
`androidx.media3.transformer.ExportException`	If no suitable `Codec` can be created.

createForVideoDecoding

fun createForVideoDecoding(
    format: Format!,
    outputSurface: Surface!,
    requestSdrToneMapping: Boolean,
    logSessionId: LogSessionId?
): Codec!

Returns a Codec for video decoding.

Parameters
`format: Format!`	The `Format` (of the input data) used to determine the underlying decoder and its configuration values.
`outputSurface: Surface!`	The `Surface` to which the decoder output is rendered.
`requestSdrToneMapping: Boolean`	Whether to request tone-mapping to SDR.
`logSessionId: LogSessionId?`	The optional `LogSessionId` of the `android.media.metrics.EditingSession`.

Returns
`Codec!`	A `Codec` for video decoding.

Throws
`androidx.media3.transformer.ExportException`	If no suitable `Codec` can be created.
