TrackSelectionParameters

@UnstableApi
public static final TrackSelectionParameters DEFAULT_WITHOUT_CONTEXT

An instance with default values, except those obtained from the Context.

If possible, use getDefaults instead.

This instance will not have the following settings:

• Viewport constraints configured for the primary display.
• Preferred text language and role flags configured to the accessibility settings of CaptioningManager.

@UnstableApi
protected static final int FIELD_CUSTOM_ID_BASE = 1000

Defines a minimum field ID value for subclasses to use when implementing toBundle and delegating to Builder.

Subclasses should obtain keys for their Bundle representation by applying a non-negative offset on this constant and passing the result to intToStringMaxRadix.

@UnstableApi
public final TrackSelectionParameters.AudioOffloadPreferences audioOffloadPreferences

The preferred offload mode settings for audio playback. The default is DEFAULT.

public final ImmutableSet<@C.TrackType Integer> disabledTrackTypes

The track types that are disabled. No track of a disabled type will be selected, thus no track type contained in the set will be played. The default value is that no track type is disabled (empty set).

public final boolean forceHighestSupportedBitrate

Whether to force selection of the highest bitrate audio and video tracks that comply with all other constraints. The default value is false.

public final boolean forceLowestBitrate

Whether to force selection of the single lowest bitrate audio and video tracks that comply with all other constraints. The default value is false.

@C.SelectionFlags
public final int ignoredTextSelectionFlags

Bitmask of selection flags that are ignored for text track selections. See . The default value is 0 (i.e., no flags are ignored).

@UnstableApi
public final boolean isPrioritizeImageOverVideoEnabled

Whether an image track will be selected over a video track if both are available. The default value is false.

public final int maxAudioBitrate

Maximum allowed audio bitrate in bits per second. The default value is MAX_VALUE (i.e. no constraint).

public final int maxAudioChannelCount

Maximum allowed audio channel count. The default value is MAX_VALUE (i.e. no constraint).

public final int maxVideoBitrate

Maximum allowed video bitrate in bits per second. The default value is MAX_VALUE (i.e. no constraint).

public final int maxVideoFrameRate

Maximum allowed video frame rate in hertz. The default value is MAX_VALUE (i.e. no constraint).

public final int maxVideoHeight

Maximum allowed video height in pixels. The default value is MAX_VALUE (i.e. no constraint).

To constrain adaptive video track selections to be suitable for a given viewport (the region of the display within which video will be played), use (viewportWidth, viewportHeight and viewportOrientationMayChange) instead.

public final int maxVideoWidth

Maximum allowed video width in pixels. The default value is MAX_VALUE (i.e. no constraint).

To constrain adaptive video track selections to be suitable for a given viewport (the region of the display within which video will be played), use (viewportWidth, viewportHeight and viewportOrientationMayChange) instead.

public final int minVideoBitrate

Minimum allowed video bitrate in bits per second. The default value is 0 (i.e. no constraint).

public final int minVideoFrameRate

Minimum allowed video frame rate in hertz. The default value is 0 (i.e. no constraint).

public final int minVideoHeight

Minimum allowed video height in pixels. The default value is 0 (i.e. no constraint).

public final int minVideoWidth

Minimum allowed video width in pixels. The default value is 0 (i.e. no constraint).

public final ImmutableMap<TrackGroup, TrackSelectionOverride> overrides

Overrides to force selection of specific tracks.

public final ImmutableList<String> preferredAudioLanguages

The preferred languages for audio and forced text tracks as IETF BCP 47 conformant tags in order of preference. An empty list selects the default track, or the first track if there's no default. The default value is an empty list.

public final ImmutableList<String> preferredAudioMimeTypes

The preferred sample MIME types for audio tracks in order of preference, or an empty list for no preference. The default is an empty list.

@C.RoleFlags
public final int preferredAudioRoleFlags

The preferred C.RoleFlags for audio tracks. 0 selects the default track if there is one, or the first track if there's no default. The default value is 0.

public final ImmutableList<String> preferredTextLanguages

The preferred languages for text tracks as IETF BCP 47 conformant tags in order of preference. An empty list selects the default track if there is one, or no track otherwise. The default value is an empty list, or the language of the accessibility CaptioningManager if enabled.

@C.RoleFlags
public final int preferredTextRoleFlags

The preferred C.RoleFlags for text tracks. 0 selects the default track if there is one, or no track otherwise. The default value is 0, or ROLE_FLAG_SUBTITLE | ROLE_FLAG_DESCRIBES_MUSIC_AND_SOUND if the accessibility CaptioningManager is enabled.

public final ImmutableList<String> preferredVideoMimeTypes

The preferred sample MIME types for video tracks in order of preference, or an empty list for no preference. The default is an empty list.

@C.RoleFlags
public final int preferredVideoRoleFlags

The preferred C.RoleFlags for video tracks. 0 selects the default track if there is one, or the first track if there's no default. The default value is 0.

public final boolean selectUndeterminedTextLanguage

Whether a text track with undetermined language should be selected if no track with preferredTextLanguages is available, or if preferredTextLanguages is unset. The default value is false.

public final int viewportHeight

Viewport height in pixels. Constrains video track selections for adaptive content so that only tracks suitable for the viewport are selected. The default value is the physical height of the primary display, in pixels.

public final boolean viewportOrientationMayChange

Whether the viewport orientation may change during playback. Constrains video track selections for adaptive content so that only tracks suitable for the viewport are selected. The default value is true.

public final int viewportWidth

Viewport width in pixels. Constrains video track selections for adaptive content so that only tracks suitable for the viewport are selected. The default value is the physical width of the primary display, in pixels.

public TrackSelectionParameters.Builder buildUpon()

Creates a new Builder, copying the initial values from this instance.

public static TrackSelectionParameters fromBundle(Bundle bundle)

Construct an instance from a Bundle produced by toBundle.

public static TrackSelectionParameters getDefaults(Context context)

Returns an instance configured with default values.
