VobSub subtitles in Web Player do not work.
I'm using MKV's with embedded subtitles. The server transcodes. Subtitles will display for a while (around 1-30 min), then disappear completely (sometimes after a few seconds of desync). Switching subtitles to none and back will fix this for another period, and then the same thing happens.
SRT works fine, this happens with VobSub only, but with every file containing vobsubs. Language doesn't matter, VobSub track # doesn't matter.
