# 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This page is partly outdated since we switched to voctomix, see [[:voctomix]]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
#### DV Switch
##### Stop streaming / opt out (recording goes on)
put a nice picture at /opt/voc/share/nostream.png 
  sudo sdi-script stop saalN-sd-dvswitch
  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
   https://cdn.c3voc.de/hls/s5_native_hd.m3u8

### Recording
##### DV Switch
###### stop recording
  sudo sv stop dvsink
  
###### start recording
  sudo sv start dvsink

###### Start recording at 10 am
  echo "sudo sv start dvsink" | at 10:00

#### HD Chain
Note: The screen session has the same name as the script

##### 1080p - Stereo start/stop
   sudo sdi-script start recording-hd-ts-stereo
 
### Grabber
##### Start / stop grabber source
   sudo sv start / stop / restart grabbersource

### Tracker
#### start tracker-scripts
  sudo /opt/crs/tools/tracker3.0/start-screenrc-dv.sh
or for the TS chain:
  sudo /opt/crs/tools/tracker3.0/start-screenrc-ts.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

Note: this script currently assumes that the mountpoints' target directories already exist.
### Releasing
This usually is not done on the cube, make sure you know what you are doing
