> Obviously, this is slower. Sometimes much slower (depending on the file).
Anecdotally, I’d change that “sometimes” to “often”. After years of using `exact` I finally stopped. It always felt that the wait was longer than going to the previous keyframe and rewatching the bit. Now if I could only find the perfect timing to go back, though.
A lot of stuff I watch is 720p, and it's okay with that. But with some types of higher quality files it can be (very) slow.
That said, I have replaced most of my "exact seeks" with "sub-seek"; in input.conf:
Alt+Right sub-seek 1 # Go to next/previous sub (within demuxer-readahead-secs)
Alt+d sub-seek 1
Alt+Left sub-seek -1
Alt+a sub-seek -1
And then in mpv.conf:
demuxer-readahead-secs=120 # sub-seek only works within this cache
demuxer-hysteresis-secs=60 # Fill cache only if lower than this; saves battery
This allows me to fairly quickly skip past stuff that's not too interesting, while still actually following the gist of what's going on.
I think it's also bound by default, but I'm not sure what that is from the top of my head. You'll definitely need to set that cache as it's only 2 seconds or so by default.
