This page describes the operation of the our encoder cubes Encoder Cubes.

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
Note: The screen session has the same name as the script
streams starten
sudo sdi-script start slides-ffmpeg sudo sdi-script start hd-ffmpeg
lokal testing

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
