do you know if #vlc (or possibly #mpv, I could switch to use that, but I'm not interested in using players that are not in debian) has a command to skip forwards in a video to the next time for which there is a subtitle? to get to the next part of the video with somebody actually speaking, or a reasonable approximation of that.
Searching on the internet I've found a few people asking for this (with no answers) and a “no such feature” reply from 2015, but things may have changed?
