How to create an HLS live streaming on iOS?

To create an HLS live streaming on iOS, you can follow these general steps:

1. Set Up Your Streaming Server: You need a server that supports HLS (HTTP Live Streaming). This server will segment your video into small chunks and create a playlist file that points to these chunks.

2. Capture Video: Use AVFoundation to capture video from the device's camera. You can create an AVCaptureSession and configure it with the appropriate input (camera) and output (movie file output).

3. Encode Video: Encode the captured video into H.264 format, which is required for HLS. You can use AVAssetWriter and AVAssetWriterInput to encode the video.

4. Segment Video: Segment the encoded video into small chunks (typically 10 seconds each). This can be done using AVAssetExportSession with the AVAssetExportPresetAppleM4V preset.

5. Create Playlist: Create an M3U8 playlist file that lists the video segments. This file will be used by the HLS player to stream the video.

6. Upload Segments and Playlist: Upload the video segments and the playlist file to your streaming server.

7. Play the Stream: Use AVPlayer to play the HLS stream in your iOS app. You can initialize AVPlayer with the URL of the M3U8 playlist.

For more detailed information on capturing and encoding video, you can refer to the session Build compelling spatial photo and video experiences (00:05:21) from WWDC 2024, which covers the basics of using AVFoundation for video capture and encoding.

Additionally, if you are interested in enhancing your HLS stream with interstitials (ads or other auxiliary content), you can check out the session Enhance ad experiences with HLS interstitials (00:00:57) for more information on how to insert interstitials into your HLS stream.
