setVideoFilterConfiguration()

setVideoFilterConfiguration(videoFilterConfiguration): Promise<void>

Note: This API is only supported on Android. On other platforms, the method safely performs no action.

Applies a video filter configuration to the current player instance.

This method allows defining constraints that influence how the player selects video tracks (e.g., limiting resolution, bitrate, or frame rate). The configuration is forwarded to the native Android player module.

When the configuration is successfully applied, the player emits a EventType.TrackModelChanged event, signalling that the active or selectable video tracks may have been updated.

Parameters

Parameter	Type	Description
videoFilterConfiguration	VideoFilterConfiguration	A set of video selection constraints. See VideoFilterConfiguration for full parameter details. If an empty object is provided, the player applies no filtering constraints.

Returns

Promise<void>

A promise that resolves once the configuration has been applied on the native layer.

Example

await player.getTrackManager().setVideoFilterConfiguration({
  maxBitrate: 2_000_000,
  maxFramerate: 30,
  maxHeight: 720,
});
