Summary
Documents how to limit the resolution of Millicast (OptiView Real-time) streams with the OptiView Player, so the Millicast player pages cover the APIs that already shipped.
millicast/playback/players-sdks/web/player), available since 11.13.0:player.abr.preferredMaximumResolution = { width, height }caps the resolution during playback without reconnecting. Set it toundefinedto remove the cap.source.abr.restrictToPlayerSize = truecaps the stream to the smallest layer that still covers the player's rendered size and updates when the player is resized. For Millicast this applies only when set explicitly totrue; unlike HLS/DASH, it is not on by default on mobile.connectOptions.layer.maxWidth/maxHeight. Removing the cap returns to the full ABR range, not to theconnectOptions.layervalues.theoplayer.abr.preferredMaximumResolution = CGSize(...). Set it to.zeroto remove the cap.player.abr.preferredMaximumResolution = Size(...). Set it tonullto remove the cap. Selecting a quality withtargetQualitypins playback to that layer and turns off ABR; while a layer is pinned, the cap is ignored.Behaviour and version numbers come from the SDK implementations and the SDK release notes (11.5.0 and 11.13.0).
