Constants

CREATOR

public static final Bundleable.Creator<DefaultTrackSelector.ParametersCREATOR

Object that can restore Parameters from a Bundle.

DEFAULT

public static final DefaultTrackSelector.Parameters DEFAULT

DEFAULT_WITHOUT_CONTEXT

public static final DefaultTrackSelector.Parameters DEFAULT_WITHOUT_CONTEXT

If possible, use getDefaults instead.

This instance will not have the following settings:

Public fields

allowAudioMixedChannelCountAdaptiveness

public final boolean allowAudioMixedChannelCountAdaptiveness

Whether to allow adaptive audio selections containing mixed channel counts. Adaptations between different channel counts may not be completely seamless. The default value is false.

public final boolean allowAudioMixedDecoderSupportAdaptiveness

Whether to allow adaptive audio selections with mixed levels of and .

allowAudioMixedMimeTypeAdaptiveness

public final boolean allowAudioMixedMimeTypeAdaptiveness

Whether to allow adaptive audio selections containing mixed MIME types. Adaptations between different MIME types may not be completely seamless, in which case allowAudioNonSeamlessAdaptiveness also needs to be true for mixed MIME type selections to be made. The default value is false.

allowAudioMixedSampleRateAdaptiveness

public final boolean allowAudioMixedSampleRateAdaptiveness

Whether to allow adaptive audio selections containing mixed sample rates. Adaptations between different sample rates may not be completely seamless. The default value is false.

Whether to allow adaptive audio selections where adaptation may not be completely seamless. The default value is true.

allowInvalidateSelectionsOnRendererCapabilitiesChange

public final boolean allowInvalidateSelectionsOnRendererCapabilitiesChange

Whether to allow to invalidate selections on renderer capabilities change. The default value is false.

allowMultipleAdaptiveSelections

public final boolean allowMultipleAdaptiveSelections

Whether multiple adaptive selections with more than one track are allowed. The default value is true.

Note that tracks are only eligible for adaptation if they define a bitrate, the renderers support the tracks and allow adaptation between them, and they are not excluded based on other track selection parameters.

allowVideoMixedDecoderSupportAdaptiveness

public final boolean allowVideoMixedDecoderSupportAdaptiveness

Whether to allow adaptive video selections with mixed levels of and .

allowVideoMixedMimeTypeAdaptiveness

allowVideoNonSeamlessAdaptiveness

public final boolean allowVideoNonSeamlessAdaptiveness

Whether to allow adaptive video selections where adaptation may not be completely seamless. The default value is true.

constrainAudioChannelCountToDeviceCapabilities

public final boolean constrainAudioChannelCountToDeviceCapabilities

Whether to constrain audio track selection so that the selected track's channel count does not exceed the device's output capabilities. The default value is true.

exceedAudioConstraintsIfNecessary

Whether to exceed the maxAudioChannelCount and maxAudioBitrate constraints when no selection can be made otherwise. The default value is true.

exceedRendererCapabilitiesIfNecessary

public final boolean exceedRendererCapabilitiesIfNecessary

Whether to exceed renderer capabilities when no selection can be made otherwise.

This parameter applies when all of the tracks available for a renderer exceed the renderer's reported capabilities. If the parameter is true then the lowest quality track will still be selected. Playback may succeed if the renderer has under-reported its true capabilities. If false then no track will be selected. The default value is true.

exceedVideoConstraintsIfNecessary

public final boolean exceedVideoConstraintsIfNecessary

Whether to exceed the maxVideoWidth, maxVideoHeight and maxVideoBitrate constraints when no selection can be made otherwise. The default value is true.
