@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setAudioOffloadPreferences(

)

Sets the audio offload mode preferences. This includes whether to enable/disable offload as well as to set requirements like if the device must support gapless transitions or speed change during offload.

@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setConstrainAudioChannelCountToDeviceCapabilities(boolean enabled)

Whether to only select audio tracks with channel counts that don't exceed the device's output capabilities. The default value is true.

When enabled, the track selector will prefer stereo/mono audio tracks over multichannel if the audio cannot be spatialized or the device is outputting stereo audio. For example, on a mobile device that outputs non-spatialized audio to its speakers. Dolby surround sound formats are excluded from these constraints because some Dolby decoders are known to spatialize multichannel audio on Android OS versions that don't support the API.

For devices with Android 12L+ that support audio spatialization, when this is enabled the track selector will trigger a new track selection everytime a change in spatialization properties is detected.

The constraints do not apply on devices with television UI mode.

The constraints do not apply when the track selector is created without a reference to a Context via the deprecated DefaultTrackSelector constructor.

@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setExceedAudioConstraintsIfNecessary(

@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setExceedRendererCapabilitiesIfNecessary(
    boolean exceedRendererCapabilitiesIfNecessary
)

Sets 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.

@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setExceedVideoConstraintsIfNecessary(
    boolean exceedVideoConstraintsIfNecessary
)

Sets whether an image track would be selected over a video track if both are available.

@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setRendererDisabled(int rendererIndex, boolean disabled)

Sets whether the renderer at the specified index is disabled. Disabling a renderer prevents the selector from selecting any tracks for it.

@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setSelectUndeterminedTextLanguage(
    boolean selectUndeterminedTextLanguage
)

Sets whether a text track with undetermined language should be selected if no track with a preferred language is available, or if the preferred language is unset.

@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setSelectionOverride(
    int rendererIndex,
    TrackGroupArray groups,
    @Nullable DefaultTrackSelector.SelectionOverride override
)

Overrides the track selection for the renderer at the specified index.

When the TrackGroupArray mapped to the renderer matches the one provided, the override is applied. When the TrackGroupArray does not match, the override has no effect. The override replaces any previous override for the specified for the specified Renderer.

Passing a null override will cause the renderer to be disabled when the mapped to it matches the one provided. When the TrackGroupArray does not match a null override has no effect. Hence a null override differs from disabling the renderer using setRendererDisabled because the renderer is disabled conditionally on the TrackGroupArray mapped to it, where-as setRendererDisabled disables the renderer unconditionally.

To remove overrides use clearSelectionOverride, clearSelectionOverrides or clearSelectionOverrides.

@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setTrackTypeDisabled(@C.TrackType int trackType, boolean disabled)

Sets whether a track type is disabled. If disabled, no tracks of the specified type will be selected for playback.

@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setTunnelingEnabled(boolean tunnelingEnabled)

Sets whether to enable tunneling if possible. Tunneling will only be enabled if it's supported by the audio and video renderers for the selected tracks.

Tunneling is known to have many device specific issues and limitations. Manual testing is strongly recommended to check that the media plays correctly when this option is enabled. See:

• google/ExoPlayer#9133
• google/ExoPlayer#9317

    int viewportWidth,
    int viewportHeight,
    boolean viewportOrientationMayChange
)

Sets the viewport size to constrain adaptive video selections so that only tracks suitable for the viewport are selected.

@CanIgnoreReturnValue
public DefaultTrackSelector.Parameters.Builder setViewportSizeToPhysicalDisplaySize(
    Context context,
    boolean viewportOrientationMayChange
)

Equivalent to calling setViewportSize with the viewport size obtained from getCurrentDisplayModeSize.

@CanIgnoreReturnValue
