DefaultCodec

DefaultCodec(
    context: Context!,
    configurationFormat: Format!,
    configurationMediaFormat: MediaFormat!,
    mediaCodecName: String!,
    isDecoder: Boolean,
    outputSurface: Surface?
)

Creates a DefaultCodec.

fun getInputFormat(): Format!

Returns the Format accepted by the codec.

This format may differ from the Format returned by getConfigurationFormat, depending on the underlying codec and configuration format requested.

fun getName(): String!

Returns the name of the underlying codec.

This name is of the actual codec, which may not be the same as the mediaCodecName passed to DefaultCodec.

fun isEnded(): Boolean

Returns whether the Codec's output stream has ended, and no more data can be dequeued.

@EnsuresNonNullIf(expression = "#1.data", result = true)
fun maybeDequeueInputBuffer(inputBuffer: DecoderInputBuffer!): Boolean

Dequeues a writable input buffer, if available.

This method must not be called from video encoders because they must use a Surface to receive input.

fun queueInputBuffer(inputBuffer: DecoderInputBuffer!): Unit

Queues an input buffer to the Codec. No buffers may be queued after end of stream buffer has been queued.

This method must not be called from video encoders because they must use a Surface to receive input.

fun release(): Unit

Releases the Codec.

fun releaseOutputBuffer(render: Boolean): Unit

Releases the current output buffer.

Only set render to true when the Codec is a video decoder. Setting render to true will first render the buffer to the output surface. In this case, the surface will release the buffer back to the Codec once it is no longer used/displayed.

This should be called after the buffer has been processed. The next output buffer will not be available until the current output buffer has been released.

Calling this method with render set to true is equivalent to calling releaseOutputBuffer with the presentation timestamp of the output buffer info.

fun releaseOutputBuffer(renderPresentationTimeUs: Long): Unit

Renders and releases the current output buffer.

This method must only be called on video decoders.

This method will first render the buffer to the output surface. The surface will then release the buffer back to the Codec once it is no longer used/displayed.

This should be called after the buffer has been processed. The next output buffer will not be available until the current output buffer has been released.

fun signalEndOfInputStream(): Unit

Signals end-of-stream on input to a video encoder.

This method must only be called on video encoders because they must use a Surface as input. For audio/video decoders or audio encoders, the BUFFER_FLAG_END_OF_STREAM flag should be set on the last input buffer queued.

@VisibleForTesting
protected fun releaseOutputBuffer(render: Boolean, renderPresentationTimeUs: Long): Unit

Releases the output buffer at renderPresentationTimeUs if render is true, otherwise release the buffer without rendering.
