Extract CMSampleBuffer from HLS video stream on iOS

How can I save what AVPlayer is currently playing (both video and audio) from Live HLS stream?

I know how to load and play m3u8 video file using AVPlayer.

Please note that the HLS stream is live and not Video on demand so cannot use AVAggregateAssetDownloadTask In the perfect scenario will get CMSampleBuffer objects which can save to file easily. Also AVPlayerItemOutput is not entirely an option because I am unable to see how will get the audio channel.

Solution

  • Seems not possible with the current SDK. I've implemented it using ffmpeg
