Hello,We have the following stream setup, with WebVTT closed captions in the master index. The question is: (1) Can AVPlayer render WebVTT Closed Captions?(2) How can I determine if WebVTT Closed Captions exist on an asset? (3) How can I enable/disable WebVTT Closed Captions on the AVPlayer during playback?Thanks,Mikeindex.m3u8 #EXTM3U #EXT-X-VERSION:4 #EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="group00",NAME="lang",DEFAULT=YES,FORCED=NO,LANGUAGE="en",URI="04.m3u8" #EXT-X-STREAM-INF:BANDWIDTH=353933,AVERAGE-BANDWIDTH=192512,RESOLUTION=320x180,CODECS="avc1.4d400c,mp4a.40.5",SUBTITLES="group00" 01.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=486658,AVERAGE-BANDWIDTH=264704,RESOLUTION=320x180,CODECS="avc1.4d400c,mp4a.40.5",SUBTITLES="group00" 02.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=694041,AVERAGE-BANDWIDTH=377504,RESOLUTION=384x216,CODECS="avc1.4d400d,mp4a.40.5",SUBTITLES="group00" 03.m3u804.m3u8 #EXTM3U #EXT-X-VERSION:3 #EXT-X-TARGETDURATION:7 #EXT-X-MEDIA-SEQUENCE:109580 #EXTINF:6, 20151102T165342-04-109580.vtt #EXTINF:6, 20151102T165342-04-109581.vtt #EXTINF:6, 20151102T165342-04-109582.vtt #EXTINF:6, 20151102T165342-04-109583.vtt #EXTINF:6, 20151102T165342-04-109584.vtt #EXTINF:6, 20151102T165342-04-109585.vtt20151102T165342-04-109581.vtt WEBVTT X-TIMESTAMP-MAP=MPEGTS:450000, LOCAL:291:38:00.895 302:17:48.200 --> 302:17:48.280 align:start position:71% line:91% size:56% PLEASE! 302:17:48.280 --> 302:17:49.520 align:start position:65% line:91% size:68% NO MORE FRIES! 302:17:49.520 --> 302:17:52.360 align:start position:69% line:91% size:60% ( GAGS ) 302:17:52.360 --> 302:17:54.200 align:start position:64% line:91% size:70% Steven: FRYBO, STOP!
