iOS 10下，AVplayer新增屬性 automaticallyWaitsToMinimizeStalling。

蘋果官方文檔地址https://developer.apple.com/reference/avfoundation/avplayer/1643482-automaticallywaitstominimizestal

HTTP Live Streaming (HLS): When playing HLS media, the player behaved as if automaticallyWaitsToMinimizeStalling is true.

File-based Media: When playing file-based media, including PRogressively downloaded content, the player behaved as if automaticallyWaitsToMinimizeStalling is false.

文檔中的兩句話

HTTP Live Streaming (HLS): 當(dāng)播放HLS媒體時(shí), automaticallyWaitsToMinimizeStalling 的值為 true.

File-based Media: 當(dāng)播放基于文件的媒體, 包括逐漸下載的內(nèi)容, automaticallyWaitsToMinimizeStalling 的值為 false.

avplayer在新系統(tǒng)下有時(shí)會(huì)播放不了

self.player.automaticallyWaitsToMinimizeStalling = NO;

一句話解決。
