Hi, i read about exoplayer supporting .srt subtitles and found code about how to enable it from here http://emby.media/community/index.php?/topic/3688-hls-streaming-video-supports-subtitles/. But as i was looking more into the topic i found that .m3u8 can have subtitle metadata in it:
for example if you open the https://devimages.apple.com.edgekey.net/streaming/examples/bipbop_16x9/bipbop_16x9_variant.m3u8 in per say notepad it contains:
#EXTM3U

#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="bipbop_audio",LANGUAGE="eng",NAME="BipBop Audio 2",AUTOSELECT=NO,DEFAULT=NO,URI="alternate_audio_aac_sinewave/prog_index.m3u8"

full thread here http://emby.media/community/index.php?/topic/3688-hls-streaming-video-supports-subtitles/.
and if i run this stream in Quicktime player on my mac i can select subtitles.

Does android exoplayer support this type of subtitles?

Yes, this is already supported in exoplayer. You can chose any of the subtitles declared in the master playlist. This same HLS sample is available in the DemoApp, so you can have a look there.

found it already. https://google.github.io/ExoPlayer/guide.html Thanks!
