Certain subtitle formats cannot be directly streamed, so your server is probably re-encoding video on the fly to burn in the subtitles. PGS format is actually a series of images and will always require re-encoding video. Picking SRT should work with device direct streaming.

Ibram X. Kendi said something about this that made me stop using the term “white trash”. Basically, the idea of the term is that “white trash” don’t uphold the virtue of whiteness, that whiteness is goodness, and white trash are white in skin color only. Thus, using the term supports white supremacy, whether or not you realize it.

So thank you for saying something, even if it’s unpopular.
