Method Summary

Modifier and Type	Method and Description
int	getAdaptiveSupport(int rendererIndex, int groupIndex, boolean includeCapabilitiesExceededTracks) Returns the extent to which a renderer supports adaptation between supported tracks in a specified TrackGroup.
int	getAdaptiveSupport(int rendererIndex, int groupIndex, int[] trackIndices) Returns the extent to which a renderer supports adaptation between specified tracks within a TrackGroup.
int	getRendererSupport(int rendererIndex) Returns the extent to which a renderer can play the tracks in the track groups mapped to it.
int	getTrackFormatSupport(int rendererIndex, int groupIndex, int trackIndex) Returns the extent to which an individual track is supported by the renderer.
TrackGroupArray	getTrackGroups(int rendererIndex) Returns the TrackGroups mapped to the renderer at the specified index.
int	getTrackTypeRendererSupport(int trackType) Returns the best level of support obtained from getRendererSupport(int) for all renderers of the specified track type.

Method Detail

getTrackGroups

public TrackGroupArray getTrackGroups(int rendererIndex)

Returns the TrackGroups mapped to the renderer at the specified index.

Parameters:

rendererIndex - The renderer index.

Returns:

The corresponding TrackGroups.

getRendererSupport

public int getRendererSupport(int rendererIndex)

Returns the extent to which a renderer can play the tracks in the track groups mapped to it.

Parameters:

rendererIndex - The renderer index.

Returns:

One of RENDERER_SUPPORT_PLAYABLE_TRACKS, RENDERER_SUPPORT_EXCEEDS_CAPABILITIES_TRACKS, RENDERER_SUPPORT_UNSUPPORTED_TRACKS and RENDERER_SUPPORT_NO_TRACKS.

getTrackTypeRendererSupport

public int getTrackTypeRendererSupport(int trackType)

Returns the best level of support obtained from getRendererSupport(int) for all renderers of the specified track type. If no renderers exist for the specified type then RENDERER_SUPPORT_NO_TRACKS is returned.

Parameters:

trackType - The track type. One of the C TRACK_TYPE_* constants.

Returns:

One of RENDERER_SUPPORT_PLAYABLE_TRACKS, RENDERER_SUPPORT_EXCEEDS_CAPABILITIES_TRACKS, RENDERER_SUPPORT_UNSUPPORTED_TRACKS and RENDERER_SUPPORT_NO_TRACKS.

getTrackFormatSupport

public int getTrackFormatSupport(int rendererIndex,
                                 int groupIndex,
                                 int trackIndex)

Returns the extent to which an individual track is supported by the renderer.

Parameters:

rendererIndex - The renderer index.

groupIndex - The index of the track group to which the track belongs.

trackIndex - The index of the track within the track group.

Returns:

One of RendererCapabilities.FORMAT_HANDLED, RendererCapabilities.FORMAT_EXCEEDS_CAPABILITIES, RendererCapabilities.FORMAT_UNSUPPORTED_DRM, RendererCapabilities.FORMAT_UNSUPPORTED_SUBTYPE and RendererCapabilities.FORMAT_UNSUPPORTED_TYPE.

getAdaptiveSupport

public int getAdaptiveSupport(int rendererIndex,
                              int groupIndex,
                              boolean includeCapabilitiesExceededTracks)

Returns the extent to which a renderer supports adaptation between supported tracks in a specified TrackGroup.

Tracks for which getTrackFormatSupport(int, int, int) returns RendererCapabilities.FORMAT_HANDLED are always considered. Tracks for which getTrackFormatSupport(int, int, int) returns RendererCapabilities.FORMAT_UNSUPPORTED_DRM, RendererCapabilities.FORMAT_UNSUPPORTED_TYPE or RendererCapabilities.FORMAT_UNSUPPORTED_SUBTYPE are never considered. Tracks for which getTrackFormatSupport(int, int, int) returns RendererCapabilities.FORMAT_EXCEEDS_CAPABILITIES are considered only if includeCapabilitiesExceededTracks is set to true.

Parameters:

rendererIndex - The renderer index.

groupIndex - The index of the track group.

includeCapabilitiesExceededTracks - True if formats that exceed the capabilities of the renderer should be included when determining support. False otherwise.

Returns:

One of RendererCapabilities.ADAPTIVE_SEAMLESS, RendererCapabilities.ADAPTIVE_NOT_SEAMLESS and RendererCapabilities.ADAPTIVE_NOT_SUPPORTED.

getAdaptiveSupport

public int getAdaptiveSupport(int rendererIndex,
                              int groupIndex,
                              int[] trackIndices)

Returns the extent to which a renderer supports adaptation between specified tracks within a TrackGroup.

Parameters:

rendererIndex - The renderer index.

groupIndex - The index of the track group.

Returns:

One of RendererCapabilities.ADAPTIVE_SEAMLESS, RendererCapabilities.ADAPTIVE_NOT_SEAMLESS and RendererCapabilities.ADAPTIVE_NOT_SUPPORTED.

getUnassociatedTrackGroups

public TrackGroupArray getUnassociatedTrackGroups()

Returns TrackGroups not mapped to any renderer.
