-general good news:
- doesn't need fixed-length segments; ok to let x264 pick optimal keyframes and slice on those
- hls.js polls the m3u8 for new segments, scales the duration accordingly, seeking works great
- the sfx will grow by 66 KiB since that's how small hls.js can get, wait thats not good

-
-more notes
- adding -hls_flags single_file makes duration wack during playback (for both fmp4 and ts), ok once finalized and refreshed, gives no size reduction anyways
- bebop op has good keyframe spacing for testing hls.js, in particular it hops one seg back and immediately resumes if it hits eof with the explicit hls.startLoad(0); otherwise it jumps into the middle of a seg and becomes art
- can probably -c:v copy most of the time, is there a way to check for cgop? todo
