+= Encoder Cube Operation
+This page describes the operation of the our encoder cubes [[hardware:encoder|Encoder Cubes]].
+<bootnote important>This page is partly outdated since we switched to voctomix, see [[:voctomix]]</bootnote>
+== Scripts on the cubes
+The SDI-Script handles the grabbing from the SDI cards and feeds the data to the DV-Switch chain.
+This is also true if the HD chain is used with an external video mixer.
+The SDI scrip is configures "/etc/sdi-script/".
+=== Streaming

+===== Stop streaming / opt out (recording goes on)
+put a nice picture at /opt/voc/share/nostream.png

+  sudo sdi-script start saalN-sd-dvswitch-nostream
+===== start stream again
+  sudo sdi-script stop saalN-sd-dvswitch-nostream
+  sudo sdi-script start saalN-sd-dvswitch
+==== HD Chain
+<bootnote>The screen session has the same name as the script</bootnote>
+===== streams starten
+   sudo sdi-script start slides-ffmpeg
+   sudo sdi-script start hd-ffmpeg
+==== lokal testing
+   mplayer rtmp://encoder1.lan.c3voc.de:1935/stream/s1_native_sd
+==== remote urls
+   https://cdn.c3voc.de/s5_native_sd.webm

+=== Tracker
+==== start tracker-scripts
+  sudo /opt/crs/tools/tracker3.0/start-screenrc-dv.sh

+==== start encoder-scripts
+  sudo /opt/crs/tools/tracker3.0/start-screenrc-encoding-only.sh
+==== Tracker-screen
+  sudo screen -x tracker-scripts
+In the screen, you could use ctrl-a, type ':quit' and press return to quit the whole screen at once. Note that process like FFmpeg are not aborted immediately.
+==== Restore FUSE mounts, e.g. after reboot
+  sudo /opt/crs/tools/tracker3.0/bin/restore-fuse-mounts.sh
