This package uses the FFMPEG command-line tool to display waveforms
next to the current subtitle in a subed buffer. This can be a handy
way to fine-tune the start and stop times of a subtitle.
subed.el is not yet available as a package, but can be downloaded from https://github.com/rndusr/subed . It supports SRT and WebVTT files.
If images are not displayed, you may want to make sure max-image-size
is set to a value that allows short, wide images. The following code:
(add-hook 'subed-mode (lambda () (setq-local max-image-size nil)))may do the trick.
| mouse-1 | Left-click | set the subtitle start time |
| mouse-2 | Middle-click | jump to that position in MPV and play a brief sample |
| mouse-3 | Right-click | set the subtitle stop time |
| S-mouse-1 | Shift-left-click | extend the subtitle start time by subed-milliseconds-adjust |
| S-drag-mouse-1 | Drag-left-click | extend the subtitle start time based on distance dragged |
| C-mouse-1 | Ctrl-left-click | set the subtitle start time and copy it to the stop time of the previous subtitle |
| S-mouse-3 | Shift-right-click | extend the subtitle stop time by subed-milliseconds-adjust |
| S-drag-mouse-3 | Drag-right-click | extend the subtitle stop time based on distance dragged |
| C-mouse-3 | Ctrl-right-click | set the subtitle stop time and copy it to the start time of the next subtitle |
The copied start or end times respect subed-subtitle-spacing.
If the images are not displayed properly, check that max-image-size is set to nil.
