Constructor Detail

FfmpegAudioRenderer

public FfmpegAudioRenderer()

FfmpegAudioRenderer

public FfmpegAudioRenderer(Handler eventHandler,
                           AudioRendererEventListener eventListener,
                           AudioProcessor... audioProcessors)

Parameters:

eventHandler - A handler to use when delivering events to eventListener. May be null if delivery of events is not required.

eventListener - A listener of events. May be null if delivery of events is not required.

audioProcessors - Optional AudioProcessors that will process audio before output.

Method Detail

supportsFormatInternal

protected int supportsFormatInternal(Format format)

Description copied from class: SimpleDecoderAudioRenderer

Returns the RendererCapabilities.FORMAT_SUPPORT_MASK component of the return value for SimpleDecoderAudioRenderer.supportsFormat(Format).

Specified by:

supportsFormatInternal in class SimpleDecoderAudioRenderer

Parameters:

format - The format.

Returns:

The extent to which the renderer supports the format itself.

supportsMixedMimeTypeAdaptation

public final int supportsMixedMimeTypeAdaptation()
                                          throws ExoPlaybackException

Description copied from interface: RendererCapabilities

Returns the extent to which the Renderer supports adapting between supported formats that have different mime types.

Specified by:

supportsMixedMimeTypeAdaptation in interface RendererCapabilities

Overrides:

supportsMixedMimeTypeAdaptation in class BaseRenderer

Returns:

The extent to which the renderer supports adapting between supported formats that have different mime types. One of RendererCapabilities.ADAPTIVE_SEAMLESS, RendererCapabilities.ADAPTIVE_NOT_SEAMLESS and RendererCapabilities.ADAPTIVE_NOT_SUPPORTED.

Throws:

ExoPlaybackException - If an error occurs.

createDecoder

protected com.google.android.exoplayer2.ext.ffmpeg.FfmpegDecoder createDecoder(Format format,
                                                                               ExoMediaCrypto mediaCrypto)
                                                                        throws FfmpegDecoderException

Description copied from class: SimpleDecoderAudioRenderer

Creates a decoder for the given format.

Specified by:

createDecoder in class SimpleDecoderAudioRenderer

Parameters:

format - The format for which a decoder is required.

mediaCrypto - The ExoMediaCrypto object required for decoding encrypted content. Maybe null and can be ignored if decoder does not handle encrypted content.

Returns:

The decoder.

Throws:

FfmpegDecoderException

getOutputFormat

public Format getOutputFormat()

Description copied from class: SimpleDecoderAudioRenderer

Returns the format of audio buffers output by the decoder. Will not be called until the first output buffer has been dequeued, so the decoder may use input data to determine the format.

The default implementation returns a 16-bit PCM format with the same channel count and sample rate as the input.

Overrides:

getOutputFormat in class SimpleDecoderAudioRenderer
