# HLS

HLS playback is supported by our player engine with some key differences.

`PlayerEngine.apple`

- based on `AVPlayer` and other `AVFoundation` framework classes

- support for FairPlay Streaming and AirPlay

- no advanced tuning settings

## Picture in Picture

`Picture in Picture` is the ability to keep watching your video while interacting with other apps.

Due to Apple restrictions, the feature is currently available only for HLS streams played with `PlayerEngine.apple`.

Although not exactly similar to the real Picture in Picture, you can enable one of these modes for the ViewController containing our Player View.

> You can use Picture in Picture with iPad Pro, iPad Air and later, and iPad mini 2 and later.

> Make sure to enable the `Audio, AirPlay, and Picture in Picture` background mode among your app capabilities.

## High Efficiency Video Coding (HEVC/H.265)

Our player supports HLS streams with HEVC encoded media.

HLS playback with `PlayerEngine.apple` is limited to devices set with a processor newer or equal to A9 (iPhone 7 and above). Software decoding using `AVFoundation` is possible on all iOS/iPadOS devices. Our tests found that HEVC media is not playable on iPhone 6 devices.
