# E-scripts on processing and editing subtitles.
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
# (find-eev-quick-intro)
# http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

<edrx> sachac: I used this to download the automatic subtitles of
the video that I have just recorded -
https://0x0.st/oTrh.txt - but the .vtt file looks like this:
https://0x0.st/oTrC.txt
<edrx> sachac: this is tricky to edit because of the timestamps on
words - like <00:00:04.400><c> and</c><00:00:04.880><c>
this</c><00:00:05.120>...
<edrx> sachac: do you have tricks to convert that to another
format? I tried pysubs2 - more precisely: pip3 install
pysubs2; pysubs2 --help; pysubs2 --to srt *.vtt
