[ANN] EmacsConf 2020 videos are out!

Hello fellow Emacsians!

The EmacsConf 2020 videos are now ready.  Thanks to everyone who helped
make it happen!

You can check out https://emacsconf.org/2020/talks/ to find the videos,
Q&A, links, and notes for each talk.  The collaborative pad is archived
at https://emacsconf.org/2020/pad/.  We've also asked speakers to send
us any additional material or resources they would like to add to their
talk's page.

The videos are currently available in 720p (1280px x 720px, progressive)
WebM format.  We are working on transcoding and uploading low-resolution
(480p or 852px x 480px, progressive) WebM as well.

If you have questions or ideas related to the talks, please feel free to
reach out to the speaker(s).  If you think of ways to make EmacsConf
even better, we'd love to hear from you too.  You can also check out
https://www.emacswiki.org/emacs/Usergroups for meetups and workshops
happening throughout the year (and if you organize a meetup or would
like to, please contact us - we'd love to help bring people together!).
If you have any EmacsConf-related blog posts or discussions, please add
them to https://emacsconf.org/2020/ or email us so that we could add the
links.  Let's keep the conversation going!

Behind the scenes
-----------------

This year, we were again able to make EmacsConf happen entirely with
Free Software.  For the live talks and/or Q&A sessions with speakers,
we used the BigBlueButton instance graciously shared with us by the
Free Software Foundation (FSF).  The whole conference was captured
and streamed to the EmacsConf stream server running Icecast, using a
GStreamer pipeline based on a script written by Ruben Rodriguez for
streaming FSF events such as the LibrePlanet conference and FSF35.
For the collaborative pad for gathering questions and show notes, we
used an Etherpad on the Wikimedia Foundation instance hosted at
https://etherpad.wikimedia.org.  For the EmacsConf website, we used
ikiwiki.  During the conference, we used Emacs Lisp to plan the
schedule, update the topics across our IRC channels, and send automated
messages about upcoming talks to speakers and organizers, all inside
Emacs.

As we write more about our streaming setup, infrastructure, processes,
and code, we will update https://emacsconf.org/2020/ and post links to
https://lists.gnu.org/mailman/listinfo/emacsconf-discuss.
In the meantime, please don't hesitate to email me (bandali@gnu.org)
if you would like to ask about how we organized the conference.

Thanks again to everyone for an awesome EmacsConf!

Smaller size of videos could be useful - Re: [ANN] EmacsConf 2020 videos are out!

That is great. I just wish videos would be smaller in size. I am
rendering them smaller on remote server to be able to downloade them
resized. It takes time.

I have resized this video down to 26 MB, almost 10 times less. This is
because network may be very slow in some parts of the world,
additionally downloading over mobile network is pretty expensive.

Thanu you very much for such a camplete report and for so much backend
information.  Links to the details would be great.  The most interesting
of what someone does is not what is visible, but details of how it was
done so someone else can build on it.  "The sum of the parts is greater
than all the separate parts."  Congratulations!

As we’ve mentioned in the original email, we’re going to release 480p
versions of all the videos:

They should normally be available next week.

HTH,
