+
+## Process uploaded files
+
+Basic setup:
+
+1.  Set up the media server and symlinks: <a href="https://git.emacsconf.org/emacsconf-ansible/tree/README.org">README.org</a> (Media).
+2.  Set up the prerec processing areas on res: <a href="https://git.emacsconf.org/emacsconf-ansible/tree/README.org">README.org</a> (Processing prerecs).
+3.  Set up the caption processor on res: <a href="https://git.emacsconf.org/emacsconf-ansible/tree/README.org">README.org</a> (Captioning).
+
+Process:
+
+1.  Review uploaded files with <elisp:emacsconf-upload-dired>
+2.  Open the JSON for the file you want to process and use <elisp:emacsconf-upload-copy-from-json> .
+    If more than one file uses the same extension, provide a suffix to disambiguate them.
+3.  On res:
+    1.  Create a directory ~/current/files/$slug.
+    2.  Copy the uploaded file from ~/cache as `$video_slug--original.$extension`, or use `rename-original.sh $slug $file`.
+    3.  Call `process-prerec.sh $file`.
+4.  When the screens are finished, do locally:
+    1.  update-cache on my computer.
+    2.  <elisp:emacsconf-publish-cache-video-data> or <elisp:emacsconf-cache-all-video-data>
+    3.  <elisp:emacsconf-publish-backstage-index>

+2.  SSH to live0.emacsconf.org and run `/etc/init.d/emacsconf stop`. Confirm that icecast has stopped with `ps | grep emacsconf`; if not, kill the process.
+    Start it again with `/etc/init.d/emacsconf start`
+3.  To test, you can use FFmpeg like this for the gen stream:

+#### Instructions
+
+NOTE: VNC+OBS doesn&rsquo;t work well if you have a window manager that
+automatically resizes windows, like i3. Please configure your window
+manager so that the VNC window is not resized.
+
+1.  Install a VNC viewer on your system (ex: tigervnc-viewer).
+
+2.  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
+
+3.  Copy the password:
+    
+    scp emacsconf-$TRACK@res.emacsconf.org:~/.vnc/passwd vnc-passwd-$TRACK -p $SSH\_PORT
+
+4.  Forward your local ports and connect via VNC viewer to the
+    appropriate forwarded port from your laptop:
+    
+        ssh emacsconf-$TRACK@res.emacsconf.org -N -L $TRACK_PORT:127.0.0.1:$TRACK_PORT -p $SSH_PORT &
+        sleep 5   # Give it time to establish the tunnels
+        xvncviewer 127.0.0.1:$TRACK_PORT -shared -geometry 1280x720 -passwd vnc-passwd-$TRACK &
+
+If you get the following error:
+
+    channel 2: open failed: connect failed: Connection refused
+    CConn:       End of stream
+    CConn:       The connection was dropped by the server before the session could
+                 be established.
+
+then the VNC server hasn&rsquo;t started yet. You can start it with
+
+    ssh emacsconf-$TRACK@res.emacsconf.org -p $SSH_PORT /home/emacsconf-$TRACK/bin/track-vnc
+
+and then connect with:
+
+    xvncviewer 127.0.0.1:$TRACK_PORT -shared -geometry 1280x720 -passwd vnc-passwd-$TRACK &

+2.  Start **recording** (not streaming). If you don&rsquo;t see OBS when you connect, it&rsquo;s probably on workspace 2, so you can switch with Alt-2. If you still don&rsquo;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.
+
+3.  Verify with MPV on your local system:
+
