setup_pieces seems to be about 30% of the delay.

Most of the rest is slow_refresh() i.e. seek

Within seek() it's mostly get() which is

75% get_video() loop
25% display_player_video()

Maybe Butler::get_video() could optionally return AGAIN more often (i.e. if _video is empty). Then the update would be done in an idle handler.
setup_pieces() could re-use pieces? (as mentioned in 1485).

Should be better in 335ef709439cd3678f6813a3fb880110e4c9cb26 but setup_pieces() still needs to be better.

Closing unless we find other specific cases that are slow.
