背景：我在MPMoviePlayer不支持的服務器端有自定義的身份驗證機制。所以，我決定有一個本地環回HTTP服務器，它將接受播放器的初始請求並提供HLS清單文件。通過iOS上的本地HTTP服務器回放HLS
我處於播放器向本地HTTP服務器發起請求的位置，然後我的本地HTTP服務器從服務器獲取清單文件並將其作爲http響應寫回播放器。但之後MPMoviePlayer不再播放視頻。
有人可以幫助我實現這一目標嗎？

在此先感謝。
我知道這不是很有幫助，但我不確定HLS協議是否允許從本地主機播放。幾個月前，我正在嘗試一種類似的技術，並且在Apple媒體開發論壇的某個地方，我發現這是不可能的。我想離線播放，希望能夠下載.ts文件來使用配置爲流式傳輸的播放器。因爲這是不可能的，我最終只是下載了一個mp4文件並更換了我的播放器來支持它。 – timgcarlson 2014-11-24 18:18:38
假設您可以訪問Apple開發論壇，請查看此帖... https://devforums.apple.com/message/1031399#1031399（baleighsdad是Apple HLS團隊的工程師）。 – timgcarlson 2014-11-24 18:19:17
感謝您的鏈接timgcarlson。我目前正在使用MPMoviePlayerController。我正在離線使用MPMoviePlayerController成功傳輸MP4文件。我想用HLS視頻做同樣的事情。在我的場景中，我不必在本地流式傳輸整個視頻。我只是希望能夠提供HLS清單，因爲這是受客戶端證書身份驗證機制保護的，並且MPMoviePlayerController無法處理身份驗證。我應該改用AVPlayer嗎？ – Madala 2014-11-26 09:56:49
