If you specify commands when you call SSH instead of using an interactive shell, you may need to also specify DISPLAY=:5 (for the gen track) or DISPLAY=:6 (for the dev track), since ssh won’t pick up the variables from `.bashrc`. -- If you have a Wayland-only desktop without any X11 compatibility layer (example: [Sway](https://swaywm.org) with `xwayland disable`) the suggested software (`tigervnc`) might no work. You can use instead for example `gnome-remote-desktop`.

For +us, the purpose is quite simple: maximize the intelligibility of the +speaker and minimize the noise. -Pain points: +We can get great results with Audacity for the vast majority of +audio-tracks. Sometimes, however, some audio-tracks have intractable +noise-profile that require the use of model-based denoising filters that +can applied with ffmpeg. -- Many talk pages don’t have public e-mail addresses, so it takes a - little extra work (or is sometimes impossible) for people to follow - up if they have questions +We’ll start with the average Audacity workflow, and we’ll move on to the +model-based filters after. -Options: -- Do nothing (current) -- Add a mailto link to emacsconf-discuss that prepopulates the subject -- Add a mailto link to emacsconf-org - - Wider discussion -- **Add a mailto to emacsconf-org-private** - - Private feedback that can be forwarded to the speaker +#### Audacity workflow +When we process a prerec, we extract the audio of the original upload +and add it to the backstage. You should be able to find it under the +name –original.$audio\_format or –main.$audio\_format.

A person may have multiple roles. An organizer might take the lead for a role, but if you want to volunteer, speak up and they’ll probably be glad to share the load. +2. Find a moment of quiet in the video, and select it. + + We ask our speakers to include 5 seconds of quiet at the beginning or + end of their prerecs, but even if they don’t, it’s relatively. -Some roles are also described on the page.

Sometimes, however, some audio-tracks have intractable -noise-profile that require the use of model-based denoising filters that -can applied with ffmpeg. ++ + + + + + + + + + + +

I’ve also added support for tab-separated values (like Audacity label exports) and a subed-convert command to subed.el, which might give us a more concise format to work with.

We’ll - announce the schedule on the emacsconf-discuss mailing, Reddit, and - various places this week. +Goals: -- zaeph has been working on the ffmpeg incantations for preprocessing - the videos that will be submitted soon. bandali is working on - getting the FTP and web-based uploads sorted out so that speakers - can submit their videos. +- [X] Be able to start a VNC server with OBS, MPV, and Firefox, connect to it, and stream +- [X] Have another session with the sound isolated +- [-] Split the audio so that we can join the Q&A room before the MPV ends - handled by automatic scene switcher detecting mpv, but we can’t share just a window, so we might as well just wait +- [X] Control MPV from the commandline: track-mpv appears in the correct display, and it can also be controlled via the socket like this: echo ’{ “command”: [“loadfile”, “test2.webm”] }’ | socat - ~/mpv-socket-emacsconf-dev +- [ ] Share the window instead of the desktop? + +Prerequisites: + +- You need to be able to SSH out to res.emacsconf.org on port 46668 + and forward ports, so one of the main organizers needs to add your + SSH public key to the authorized\_keys file. Please e-mail your SSH + public key to sacha@sachachua.com and test that port 46668 is not + blocked. +- For streaming from OBS in VNC, you will need a VNC viewer like + tigervnc-viewer. +- For streaming from your local computer, you will need OBS and FFmpeg. + +During the conference, you will: + +- play the talk video (unless it’s automatically managed by the agenda) and update the overlays +- display intro/intermission information as needed +- open the Q&A windows, like the pad and the BBB room/IRC (unless it’s automatically managed by the agenda) +- adjust the volume if needed +- arrange windows and focus the BBB room on the speaker’s webcam if needed +- if you like, you can be responsible for managing the track from conf.org on orga@res.emacsconf.org + +Dry run checklist: + +- [ ] Connect to the server + ssh orga@res.emacsconf.org -p 46668 + emacsconf # runs emacsclient -c -a emacs +- [ ] Forward ports and connect via VNC +- [ ] Find the OBS or start it if it is not running +- [ ] Start recording +- [ ] Play a video +- [ ] Open two Firefox windows and arrange them +- [ ] Manage windows on the workspace +- [ ] Adjust the volume in OBS +- [ ] SSH to the server and play a video off-screen +- [ ] SSH to the server with X forwarding and adjust the volume off-screen + + +### Broadcasting from local OBS (option A) + +- You can copy the profile from your track or look inside it for the icecast mount point details: + - Gen: rsync -avze ’ssh -p 46668’ emacsconf-gen@res.emacsconf.org:~/.config/obs-studio/basic/profiles/ ~/.config/obs-studio/basic/profiles/ + - Dev: rsync -avze ’ssh -p 46668’ emacsconf-dev@res.emacsconf.org:~/.config/obs-studio/basic/profiles/ ~/.config/obs-studio/basic/profiles/ + +- Sacha will turn off the OBS recordings on res so that you can test streaming from your computer + - If you’re doing this independently, you can jump ahead to “Connecting to VNC” in order to stop the recording yourself + +- Verify with MPV: + + mpv https://live0.emacsconf.org/emacsconf/gen.webm + mpv https://live0.emacsconf.org/emacsconf/dev.webm + +- With luck, the 480p streams will be up automatically as well + + mpv https://live0.emacsconf.org/emacsconf/gen-480p.webm + mpv https://live0.emacsconf.org/emacsconf/dev-480p.webm + + +### Connecting to VNC (option B) + +1.

Start **recording** (not streaming). If you don’t see OBS when you connect, it’s probably on workspace 2, so you can switch with Alt-2. If you still don’t see it there, you can open a terminal with Alt-Enter and then run `track-obs`. After you start recording, confirm that it is now broadcasting to the stream. + +7. Verify with MPV on your local system: + + mpv https://live0.emacsconf.org/emacsconf/$TRACK.webm & -- I created some watch pages to support viewing different tracks: - . The livestreams won’t work yet - and it would be nice to figure out something that can dynamically - display info for recent/current/upcoming talks, but it’s a start. +8. With luck, the 480p streams will be up automatically as well.

If you specify commands when you call SSH instead of using an interactive shell, you may need to also specify DISPLAY=:5 (for the gen track) or DISPLAY=:6 (for the dev track), since ssh won’t pick up the variables from `.bashrc`. +- If you have a Wayland-only desktop without any X11 compatibility layer (example: [Sway](https://swaywm.org) with `xwayland disable`) the suggested software (`tigervnc`) might no work. You can use instead for example `gnome-remote-desktop`.

(If - you’re curious about the technical stuff, I switched to manually - splitting the text using emacsconf-reflow from emacsconf-el and then - the using aeneas for forced alignment, because I couldn’t figure out - how to get torchaudio unstuck sometimes.) - - If you don’t have the username and password for the backstage area - and you would like to access it, please e-mail me and I’ll send you - the details. +Original file: 21:16 21 minutes -- Help wanted - tech checks: For sessions with live Q&A, we’d like to - set up tech-checks with speakers to make sure that their setup works - well with BigBlueButton. A rough outline of the process is in the - tech-checking protocol heading at - . If you - would like to help with tech-checks, please e-mail us with your - general availability (including timezones) and preferred public - contact information so that we can include you on the list at - and in the e-mail to - speakers. + -- Help wanted - intro/intermission slides, OBS overlay, ??: It might - be interesting to design something to show right before and right - after a talk so that people can see the title, speaker name, talk - page URL, Q&A info, pad URL, pronouns, etc. Ideally we’d be able to - generate a whole bunch of these from the talk data, so maybe SVG or - a TikZ picture? If this is your jam, let us know. -- OBS in the cloud: We’ve been able to figure out how to stream both - streams using OBS, VNC, and PulseAudio on Ry P.’s virtual server, so - it’s even more likely that we’re going to pull off two tracks this - year. Yay! ++-- Tom Purl has joined as a captioning volunteer. Hi Tom! +-This week we hope to get lots of talks submitted, processed, and on -the way to being captioned. We’re also planning to make the captioning -workflow even better, and to improve the OBS streaming workflow. Whee! +-Sacha ++ + + + + + + + -## Volunteer update 2022-11-07 + + + + + + -Hi everyone! -Here’s what’s been happening backstage. + + + + + + -- Speakers have been submitting their videos, hooray! I added a - schedule to the backstage page at - so that people can see - how the schedule’s coming along. We expect more talks to come in the - next two weeks. Not panicking yet. =) -- Thanks to all the people who’ve been working on captions so far! - Bhavin, Andrea, and Ramin did the captions for their talks, and Jai - captioned Bala’s talk. Tom, Bhavin, and Hannah are currently working - on captions. There are three more talks backstage if anyone wants to - work on them. + + + + + + + +
