TrackSelectionParameters

@UnstableApi
const val DEFAULT_WITHOUT_CONTEXT: TrackSelectionParameters!

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 const val FIELD_CUSTOM_ID_BASE = 1000: Int

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.

fun buildUpon(): TrackSelectionParameters.Builder!

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

java-static fun fromBundle(bundle: Bundle!): TrackSelectionParameters!

Construct an instance from a Bundle produced by toBundle.

java-static fun getDefaults(context: Context!): TrackSelectionParameters!

Returns an instance configured with default values.

@UnstableApi
val audioOffloadPreferences: TrackSelectionParameters.AudioOffloadPreferences!

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

val disabledTrackTypes: ImmutableSet<@C.TrackType Int!>!

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).

val forceHighestSupportedBitrate: Boolean

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

val forceLowestBitrate: Boolean

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
val ignoredTextSelectionFlags: Int

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

@UnstableApi
val isPrioritizeImageOverVideoEnabled: Boolean

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

val maxAudioBitrate: Int

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

val maxAudioChannelCount: Int

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

val maxVideoBitrate: Int

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

val maxVideoFrameRate: Int

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

val maxVideoHeight: Int

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.

val maxVideoWidth: Int

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.

val minVideoBitrate: Int

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

val minVideoFrameRate: Int

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

val minVideoHeight: Int

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

val minVideoWidth: Int

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

val overrides: ImmutableMap<TrackGroup!, TrackSelectionOverride!>!

Overrides to force selection of specific tracks.

val preferredAudioLanguages: ImmutableList<String!>!

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.

val preferredAudioMimeTypes: ImmutableList<String!>!

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
val preferredAudioRoleFlags: Int

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.

val preferredTextLanguages: ImmutableList<String!>!

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
val preferredTextRoleFlags: Int

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.

val preferredVideoMimeTypes: ImmutableList<String!>!

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
val preferredVideoRoleFlags: Int

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.

val selectUndeterminedTextLanguage: Boolean

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.

val viewportHeight: Int

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.

val viewportOrientationMayChange: Boolean

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.

val viewportWidth: Int

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.
