- 6. Start recording. It's probably on workspace 2, so you can switch with Alt-2. Confirm that it is now broadcasting to the stream.
-
- 7. Verify with MPV on your local system:
- #+begin_example
- mpv https://live0.emacsconf.org/emacsconf/$TRACK.webm &
- #+end_example
-
- 8. With luck, the 480p streams will be up automatically as well. On your local system:
- #+begin_example
- mpv https://live0.emacsconf.org/emacsconf/$TRACK-480p.webm &
- #+end_example
-
- 9. Play a video. It should display the video and update the overlays. If you need to update the overlays manually, you can copy files from ~/data/emacsconf/overlays~ onto ~$HOME/other.png~ and ~$HOME/video.png~.
-
- #+begin_example
- cd /data/emacsconf/stream/2022
- track-mpv filename.webm
- #+end_example
-
- 10. Test Q&A. You can either wait for the video to finish or quit it with "q".
- You can paste in the URLs or use
- ~firefox /data/emacsconf/2022/index-$TRACK.html~

-Current status
+Current status:
- res.emacsconf.org seems to be able to handle 2x (OBS + TigerVNC + MPV, should test with Firefox as well)
-
+- corwin and jman will stream gen from OBS on res
+- bandali will stream dev from his laptop
+- let sachac know if you want manual control or more autopilot for the gen stream
+
Goals:
- [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
-- [X] Split the audio so that we can join the Q&A room before the MPV ends - handled by automatic scene switcher detecting mpv
-- [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
+- [-] 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

+ - 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/

+
+ - 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 "Test connecting to the VNC" in order to stop the recording yourself

+*** Connecting to the track VNC
+
+ 1. Stop broadcasting locally if you were testing local OBS.
+
+ 2. Install a VNC viewer on your system (ex: tigervnc-viewer).
+
+ 3. Set up your local environment:
+
+ - gen: export TRACK=gen; export TRACK_PORT=5905; export SSH_PORT=46668
+ - dev: export TRACK=dev; export TRACK_PORT=5906; export SSH_PORT=46668

-1. Set up your local environment
-
- gen: export TRACK=gen; export TRACK_PORT=5905
- dev: export TRACK=dev; export TRACK_PORT=5906
-
-2. Copy the vnc password file
-
- scp emacsconf-$TRACK@res:~/.vnc/passwd vnc-passwd-$TRACK
-
-3. Start up the VNC server if it's not already running
-
- ssh emacsconf-$TRACK@res.emacsconf.org "~/bin/track-vnc"
+ scp emacsconf-$TRACK@res.emacsconf.org:~/.vnc/passwd vnc-passwd-$TRACK -p $SSH_PORT
+
+ 5. Forward your local ports and connect via VNC viewer to the
+ appropriate forwarded port from your laptop:
-4. Forward your local ports
+ #+begin_example
