2160p anime lags due to subs

[TheDreadPirate]

I believe burning in subs is a transcoding task. When I watch anything with subtitles on my Chromecast with Google TV (Android TV app), it also burns in subtitles and there is a ffmpeg log. And in the ffmpeg log I see it transcoding video.

Watching that same content on my gaming PC or Android phone with the JMP client results in direct play, including subtitles.

So I would say that the problem is that JF server can't keep up. I'm leaning towards CPU limitations and not GPU.

Are you running Windows or Linux?
