Public constructors

Builder

public Builder(Context context)

Creates a new Builder.

Public methods

build

public DefaultDecoderFactory build()

Creates an instance of DefaultDecoderFactory, using defaults if values are unset.

setCodecPriority

@CanIgnoreReturnValue
public DefaultDecoderFactory.Builder setCodecPriority(
    @C.Priority @IntRange(to = C.PRIORITY_MAX) int codecPriority
)

Sets the codec priority.

Specifying codec priority allows the resource manager in the platform to reclaim less important codecs before more important codecs.

It is recommended to use predefined priorities like PRIORITY_PROCESSING_FOREGROUND, PRIORITY_PROCESSING_BACKGROUND or priority values defined relative to those defaults.

This method is a no-op on API versions before 35.

The default value is PRIORITY_PROCESSING_FOREGROUND.

Parameters
@C.Priority @IntRange(to = C.PRIORITY_MAX) int codecPriority	The C.Priority for the codec. Should be at most PRIORITY_MAX.

setEnableDecoderFallback

@CanIgnoreReturnValue
public DefaultDecoderFactory.Builder setEnableDecoderFallback(boolean enableDecoderFallback)

Sets whether the decoder can fallback.

This decides whether to enable fallback to lower-priority decoders if decoder initialization fails. This may result in using a decoder that is less efficient or slower than the primary decoder.

The default value is false.

setListener

@CanIgnoreReturnValue
public DefaultDecoderFactory.Builder setListener(DefaultDecoderFactory.Listener listener)

Sets the Listener.

setMediaCodecSelector

@CanIgnoreReturnValue
public DefaultDecoderFactory.Builder setMediaCodecSelector(MediaCodecSelector mediaCodecSelector)

Sets the MediaCodecSelector used when selecting a decoder.

The default value is DEFAULT
