Reading subtitles with VoiceOver

Hello everyone. What kind of iOS video player do you use to watch movies with subtitles? In my case (iOS 11.4.1), the only app that supports reading of subtitles is the Apple's stock "Videos" app, but, as you know, this media player has problems with the most of video formats. I tried VLC and nPlayer Plus, but haven't had a luck. Thanks in advance for any suggestions.
