Applications generally workaround this by having subtitle controls during playback that allows the user to tweak the timings of when they are displayed (e.g. +/- N).\r\n\r\nAt the moment, there is no easy way to apply (and modify) subtitle offsets. The `SubtitleParserHelper` does apply a `subtitleOffsetUs` but this is an offset taken from the `MediaFormat` and not modifiable."}}
