have demo stream with VTT closed captions embedded: https://d1e9xzui4ifg72.cloudfront.net/m3u8/sun.m3u8
00:11.000 --> 00:13.000
<v Roger Bingham>We are in New York City
00:13.000 --> 00:16.000
<v Roger Bingham>We’re actually at the Lucern Hotel, just down the street
Trying to play this stream with roku_stream_tester app, but for some reason first closed caption message appears right after video start and all other messages are out of sync as well.
Is there anything specific about VTT format I've missed or anyone had similar issues before?
