  To: Org Mode


I write a patch to add new link type:

#+begin_example
[[video:/path/to/file.mp4::00:13:20]]
#+end_example

This will open video file in specific timestamp. And it is possible to add more
options in link. Like video player arguments.

I want to ask should I add this patch to Org Mode built-in?

Here is my patch source code:

#+begin_src emacs-lisp :file "ol-video.el"
;;; [[video:/path/to/file.mp4::00:13:20]]
(defcustom org-video-link-open-command "mplayer"
  "Specify the program for openning video: link."
  :type 'string)

(defvar org-video-link-extension-list '("avi" "rmvb" "ogg" "mp4" "mkv"))

(defun org-video-link-open (uri)
  "Open video file `URI' with video player."
  (let* ((list (split-string uri "::"))
         (path (car list))
         (start-timstamp (cadr list)))
    (make-process
     :command (list org-video-link-open-command
                    "-ss" start-timstamp
                    (expand-file-name (org-link-unescape path)))
     :name "org-video-link")))

(defun org-video-complete-link (&optional arg)
  "Create a video link using completion."
  (let ((file (read-file-name "Video: " nil nil nil nil
                              #'(lambda (file)
                                  (seq-contains-p
                                   org-video-link-extension-list
                                   (file-name-extension file)))))
        (pwd (file-name-as-directory (expand-file-name ".")))
        (pwd1 (file-name-as-directory (abbreviate-file-name
                                       (expand-file-name ".")))))
    (cond ((equal arg '(16))
           (concat "video:"
                   (abbreviate-file-name (expand-file-name file))))
          ((string-match
            (concat "^" (regexp-quote pwd1) "\\(.+\\)") file)
           (concat "video:" (match-string 1 file)))
          ((string-match
            (concat "^" (regexp-quote pwd) "\\(.+\\)")
            (expand-file-name file))
           (concat "video:"
                   (match-string 1 (expand-file-name file))))
          (t (concat "video:" file)))))

(org-link-set-parameters "video"
                         :follow #'org-video-link-open
                         :complete #'org-video-complete-link)
#+end_src

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:

  https://github.com/edrx/eev/blob/UTF-8/eev-audiovideo.el#L55
  http://angg.twu.net/eev-current/eev-audiovideo.el.html
  http://angg.twu.net/eev-current/eev-audiovideo.el

I don't have a strong opinion on this, but considering Emacs does not
provide any way to play videos out of the box, I think there is no point
in shipping this with Emacs.

It can be a useful extension in ELPA, though. I suggest to add export
facilities, too.

WDYT?

Regards,

agreed.  But this is a also nice feature (provided it does not depend
on the presence of mplayer only) -- if you find a way to publish this
code and advertize it on Worg, please go ahead.

We should work on making Worg more readable and efficient in promoting
external Org libraries - there are tons of them in the wild.

Thanks,

Ok, I will push code and tutorial to Worg. I remember I added once for ob-clojure-literate.el.

Thanks Bastien
