Even "standardized" Aegisub softsubs (the staple of MKV) don't play out on many of the players, if at all.
This variety comes with responsibility what to put in it if caring about others.Ĭould be, but considering MKV's very open format system is hard to compress to play on every player (whereas MP4 can), it could be possible that MKV is a clunky old format, which has spotty reliability. If you want to be sure, you have to be responsible and put some nice AC3 in MKV. ,for example, if fan of FLAC, well, you cannot expect any player to play it. It even makes sense, srt, text file, pretty common, PGS is BD subtitle, VobSub is DVD subtitle. But WDTV Live can play all of those three within MKV and those subtitles are what I'd choose, non other. I'd go with srt or PGS or Vobsub and even those last two might be tricky for this or that player. What aegisub standardized format means? Any subtitle? You cannot expect guy or a team that writes a firmware to tuned it up for 10 subtitle formats.
With MKV you are responsible, and sure I would not put any format that is out there into it or any that is a "standard". It is something like DVD you have couple of choices and it would work. You say mp4 is good, because it is more reliable, but that is because it has its limitations, you mux into mp4 formats that you can count on your hand. I would not say clanky format, it is container., It is hard to write bulletproof firmware for 30 video, audio, subtitles. perfectly plays, even with oddball audio/video. Sure it plays great on a computer, but there is no guarantee it'll be nice and smooth on a tablet, or an Android box. Sometimes oddball format audio (most players like ac3/aac/dts) throws the MKV system in players for a loop. Could be, but considering MKV's very open format system is hard to compress to play on every player (whereas MP4 can), it could be possible that MKV is a clunky old format, which has spotty reliability.
