Hi Stardiviner,
just some quick comments on org-video-link-open...
Eev also has functions for opening audio/video files at certain time
offsets. They are called like this (with `C-e C-x C-e' or something
equivalent),
(find-video "~/eev-videos/Punch_and_Judy_Mark_Poulton-K6LmZ0A1s9U.mp4")
(find-video "~/eev-videos/Punch_and_Judy_Mark_Poulton-K6LmZ0A1s9U.mp4" "1:17")
and the sexps above pass these lists to start-process:
("mpv" "~/eev-videos/Punch_and_Judy_Mark_Poulton-K6LmZ0A1s9U.mp4"
"--fs" "--osd-level=2")
("mpv" "~/eev-videos/Punch_and_Judy_Mark_Poulton-K6LmZ0A1s9U.mp4"
"--start" "1:17"
"--fs" "--osd-level=2")
I use mpv instead of mplayer because this page at the Wikipedia
convinced me to:
https://en.wikipedia.org/wiki/Mpv_(media_player)
"--fs" means "full screen" and "--osd-level=2" shows the current time.
If you know other emacs packages that implement opening audio or video
files and skipping to a certain position please tell me - I would like
to mention them in the comments of eev-audiovideo.el. I mentioned your
previous message there, by the way! See:
