``` EncodingProfile.IsMaster=no EncodingProfile.IsMaster=yes EncodingProfile.IsMaster= Fahrplan.Room=Servus.at Lab ```

During event setup of the pipeline, you have to decide if you want leave the MPEG TS snippets only on the recording cubes or also rsync them to a central storage:

This variant is only practical if you have only one room, or at least one release encoder (aka Minions) for each recording cube. When using this variant with multiple rooms in one Tracker project (like at JEV22), you also have to set room filters in the tracker worker queues.

For every worker:

• set room filters in tracker e.g. `Fahrplan.Room = Foobar`

For every recoding cube:

• start tracker worker: `sudo systemctl start crs-worker.target`

For each minion:

• mount filesystems from encoder cube: `sudo crs-mount <storage location>`
• start tracker scripts for encoding: `sudo systemctl start crs-encoding.service`

The first variant is typically used for events with more than one room. For bigger events we use the dedicated storage server in the event server rack, for smaller events a USB connected hard drive to one of the minions might be sufficient. Each recording cube exposes the files via rsyncd, which are pulled by an rsync process running inside a screen on the storage pc.

For each encoderX start rsync on the central storage: `sudo systemctl start rsync-from-encoder@encoderX.lan.c3voc.de`

Then, start tracker workers on storage: `sudo systemctl start crs-worker.target` (only needed if you don't use `storage.lan.c3voc.de` - worker scripts get started automatically)

To allow the encoding workers to do their job, they need to mount the storage first: `sudo crs-mount <storage location>`

After mounting, you can start the tracker encoding workers: `sudo systemctl start crs-encoding.service`

The minion VMs running inside our event colo case automatically mount `storage.lan.c3voc.de` via cifs and start their worker scripts. You usually do not need to touch them.

At small events, when the talks are finished for today, you can use the recording cubes to encode master MP4 files.

First: Stop voctocore.

The rest is very similar to above, but with different mounts so `/video/capture` is not hidden:

```bash sudo mount -t cifs -o uid=voc,password= storage.lan.c3voc.de/fuse /video/fuse sudo mount -t cifs -o uid=voc,password= storage.lan.c3voc.de/video/intros /video/intros sudo mount -t cifs -o uid=voc,password= storage.lan.c3voc.de/tmp /video/tmp sudo mount -t cifs -o uid=voc,password= storage.lan.c3voc.de/encoded /video/encoded ```

Similar to variant 2, but the release encoder (minion) only mounts the /video/fuse/$room/ from each recording cube. The encoded and tmp files life on one minion, the secondary minions mount /video/encoded and /video/tmp from the primary minion. [Reason: It is not guaranteed that the minion which encoded a talk also does the postprocessing (upload) step.]

You have to set the room filters only for the recording cubes, the minions can process talks independently.

• On recording cubes: start systemd units for steps A crs-recording-scheduler, B crs-mount4cut, and C crs-cut-postprocessor
• On release encoders: start systemd units for steps D crs-encoding, E crs-postencoding, and F crs-postprocessing

optional: configure `10.73.0.2` (aka `storage.lan.c3voc.de`) on the master minion as secondary ip

on recording cubes, mount or copy the intros from their source – here `storage.lan.c3voc.de`

sudo mount -t cifs -o password= {//storage.lan.c3voc.de,}/video/intros
sudo systemctl start crs-recording-scheduler  # A
sudo systemctl start crs-mount4cut            # B
sudo systemctl start crs-cut-postprocessor    # C

# check if everything is running as expected – you might have to disable/stop the other CRS workers D-F
sudo systemctl status -n 0 crs-* 

on master minion (in this example `storage.lan.c3voc.de`)

``` mkdir -p /video/fuse/jev22/{Ahlam,Bhavani} mount -t cifs -o password= {encoder1.lan.c3voc.de,}/video/fuse/jev22/Ahlam mount -t cifs -o password= {encoder5.lan.c3voc.de,}/video/fuse/jev22/Bhavani

sudo systemctl start crs-encoding # D-encoding sudo systemctl start crs-postencoding # E-postencoding-auphonic sudo systemctl start crs-postprocessing # F-postprocessing-upload

1. check if everything is running as expected – you might have to disable/stop the other CRS workers A-C

sudo systemctl status -n 0 crs-*

```

(ensure that samba is installed on this master minion aka storage)

on other minions ``` mkdir -p /video/fuse/jev22/{Ahlam,Bhavani} mount -t cifs -o uid=voc,password= {encoder1.lan.c3voc.de,}/video/fuse/jev22/Ahlam mount -t cifs -o uid=voc,password= {encoder5.lan.c3voc.de,}/video/fuse/jev22/Bhavani mount -t cifs storage.lan.c3voc.de/encoded /video/encoded mount -t cifs -o password= storage.lan.c3voc.de/encoded /video/encoded mount -t cifs -o password= storage.lan.c3voc.de/tmp /video/tmp mount -t cifs -o password= {storage.lan.c3voc.de,}/video/intros

```

on recording cube, without intros either copy or mount the intros from their source

sudo mount -t cifs -o password= {//storage.lan.c3voc.de,}/video/intros
cd /opt/crs/tools/tracker3.0/
sudo ./start screenrc-pipeline # with steps A, B and C

on master minion (in this example minion5) ``` mount -t cifs -o password= encoder5.lan.c3voc.de/video/fuse/podstock2019/Aussenbuehne /video/fuse/podstock2019/Aussenbuehne mount -t cifs -o password= encoder6.lan.c3voc.de/video/fuse/podstock2019/Innenbuehne /video/fuse/podstock2019/Innenbuehne mount -t cifs -o password= encoder6.lan.c3voc.de/video/intros /video/intros cd /opt/crs/tools/tracker3.0/ sudo ./start screenrc-pipeline # with steps D, E, F

``` (ensure that samba is installed on this master minion)

on other minions ``` mount -t cifs -o password= {encoder5.lan.c3voc.de,}/video/fuse/podstock2019/Aussenbuehne mount -t cifs -o password= {encoder6.lan.c3voc.de,}/video/fuse/podstock2019/Innenbuehne mount -t cifs storage.lan.c3voc.de/encoded /video/encoded mount -t cifs -o password= storage.lan.c3voc.de/encoded /video/encoded mount -t cifs -o password= storage.lan.c3voc.de/tmp /video/tmp mount -t cifs -o password= {storage.lan.c3voc.de,}/video/intros cd /opt/crs/tools/tracker3.0/ sudo ./start screenrc-encoding-only # only step E
