 +### Worker Filter Examples
  
-== Pipeline setup during event+   
 +  # get all non-master tickets 
 +  EncodingProfile.IsMaster=no 
 +   
 +  # get all master tickets 
 +  EncodingProfile.IsMaster=yes 
 +   
 +  # get all recording tickets 
 +  EncodingProfile.IsMaster= 
 +   
 +  # get all tickets in this room. 
 +  Fahrplan.Room=Servus.at Lab 
 + 
 + 
 +Please note that the conditions in the "project to worker group" filter are currently always evaluated with logical OR. 
 + 
 +Specifying a property with an empty value, which is often done for `EncodingProfile.IsMaster`, will match if this property does not exist at all on a ticket. So for `EncodingProfile.IsMaster`, specifying an empty filter will match on recording tickets which never have this property.

 +## Pipeline setup during event
  
 During event setup of the pipeline, you have to decide if you want leave the MPEG TS snippets only on the [[hardware:encoder|recording cubes]] or also rsync them to a central storage: During event setup of the pipeline, you have to decide if you want leave the MPEG TS snippets only on the [[hardware:encoder|recording cubes]] or also rsync them to a central storage:
  
  
-=== centralised storage (rsync) (Variant 1)+### Simple: single-room setup (Variant A)
  
-The first variant is typically used for events with more than one room. For bigger events we use the dedicated [[hardware:event-storage|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.+{{drawio>c3tracker:setup-simple.png}}
  
-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`+This variant is practical if you have only one room, or at least one release encoder (aka [[hardware:Minion]]) for each recording encoder PC.  
 +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.
  
-==== Minion setup+For every worker: 
 +* set `EncodingProfile.IsMaster = yes` to avoid encoding all sub formats 
 +* (set room filters in tracker e.g. `Fahrplan.Room = Foobar`, but this cannot be used at the same times as the above, see the warning below)
  
-To allow the encoding workers to do their job, they need to mount the storage first: `sudo crs-mount <storage location>`+For every recoding cube: 
 +* start tracker worker: `sudo systemctl start crs-worker.target`
  
-After mounting, you can start the tracker encoding workers: `sudo systemctl start crs-encoding.service`+For each minion: 
 +* mount filesystems from encoder cube: `sudo crs-mount <storage location>` 
 +* start tracker scripts for encoding: `sudo systemctl start crs-encoding.service` 
 + 
 + 
 +<panel type="danger" title="Attention">Since tracker filters are joined via OR and not AND, this setup cannot be extended to multiple rooms without hacks if you want to e.g. limit on-site encoding to master formats. Use the  `CRS_ROOM` filter in bundlewrap if you need both tracker filters and room-specific encoding workers.</panel> 
 + 
 +### centralised storage (rsync) (Variant B) 
 + 
 +{{drawio>c3tracker:setup-central-storage.png}} 
 + 
 + 
 +This variant is typically used for events with more than one room.  
 + 
 +For bigger events we use the dedicated [[hardware:event-storage|storage]] server in the event server rack, for smaller events one of the minions is typically sufficient. If you use a minion as storage machine, you might want to configure `10.73.0.2` (aka `storage.lan.c3voc.de`) as secondary IP address to make things easier: 
 + 
 +  sudo ip a add dev br0 10.73.200.24/16 
 + 
 + 
 +Each recording encoder exposes the files via rsyncd, which are pulled by an rsync process running on this storage machine. 
 + 
 + 
 +For each encoderX start rsync on the storage machine:  
 + 
 +  sudo systemctl start rsync-from-encoder@encoderX.lan.c3voc.de 
 + 
 +If you use a minion as storage machine, you have start the tracker manually (on storage.lan.c3voc.de they are started by default):  
 + 
 +  sudo systemctl start crs-worker.target
      
-==== Cube as worker setup+which starts 
 + 
 +- crs-recording-scheduler (A) 
 +- crs-mount4cut.service   (B) 
 +- crs-cut-postprocessor   (C) 
 +- crs-encoding0, crs-encoding1 (D) 
 +- crs-postencoding        (E) 
 +- crs-postprocessing      (F) 
 + 
 + 
 + 
 +#### Minion setup 
 + 
 +To allow get additional release encoding workers on the (other) minions, you need to connect to these an mount the storage machine first:  
 + 
 +  ssh minionX.lan.c3voc.de 
 +  sudo crs-mount <storage location> 
 + 
 +After mounting, you can start the tracker encoding workers:  
 + 
 +  sudo systemctl start crs-encoding0.service 
 + 
 +The virtual minion's living in [[hardware:server-case|event colo case]] automatically mount `storage.lan.c3voc.de` via CIFS and start their worker scripts. You usually do not need to touch them. 
 +   
 + 
 +#### Encoder PCs as release encoding workers 
 + 
 +At small events, when all talks are finished for today, you can use the recording encoder PCs to encode master MP4 files.  
 + 
 +First – stop voctocore:

-=== decentralised classic (Variant 2) 
  
-The second variant is only practical if you have at least one release encoder (aka [[hardware:Minion]]) for each recording cube. When using this variant with multiple rooms, you also have to set room filters in the tracker worker queues.+### decentralised pipeline aka "even more samba" (Variant C)
  
-For every worker: +<panel type="danger" title="Attention">The "decentralized pipeline" should not be used by inexperienced users. Use the information above to find out how to get this variant working, then adjust/improve the documentation here.</panel>
-* set room filters in tracker+
  
-For every recoding cube: +Similar to variant B, but extended to work with multiple rooms. Instead of using rsync, recorded snippets remain on the encoding cubes and ''/video/fuse/$event/$room'' are exposed via samba to the minions, while the encoded and tmp files live on one "central" minion; all other minions mount ''/video/encoded'' and ''/video/tmp'' from the primary minion [reasoning: the tracker cannot guarantee that the machine which encoded a talk also does the postprocessing (upload) step, so all minions have to see the same files].
-* start tracker worker: `sudo systemctl start crs-worker.target`+
  
-For each minion: +Tracker filters have to be set only for the recording cubes, minions do not require any filters (but on smaller events without many minions, a ''EncodingProfile.IsMaster=yes'' filter can be a good idea, so sub formats won't crowd out the queues — they can always be encoded off-site later).
-* mount filesystems from encoder cube: `sudo crs-mount <storage location>` +
-* start tracker scripts for encoding: `sudo systemctl start crs-encoding.service`+
  
-=== decentralised pipeline (Variant 3)+On recording encoder PCs start the following systemd units: 
 + * ''crs-recording-scheduler'' 
 + * ''crs-mount4cut'' 
 + * ''crs-cut-postprocessor''
  
-<panel type="danger" title="Outdated">Information for "decentralized pipeline (Variant 3)" is outdated and should not be used.

-Similar to variant 2, but the release encoder (minion) only mounts the /video/fuse/$room/ from each recording cube.

 +  mount.cifs -o uid=voc,password= {//$encoder2.lan.c3voc.de,}/video/fuse/$event/$room2 
 +  ...
  
-You have to set the room filters only for the recording cubes, the minions can process talks independently.+On all minions except the one acting as storage, also mount:
  
-Modify ''/opt/crs/tools/tracker3.0/screenrc-scripts'': +  mount.cifs -o uid=voc,password= //$storage.lan.c3voc.de/encoded /video/encoded 
- * On recording cubes: comment out steps ''D-encoding'', ''E-postencoding'', and ''F-postprocessing'' +  mount.cifs -o uid=voc,password= //$storage.lan.c3voc.de/tmp /video/tmp 
- * On release encoders: comment out steps  ''A-recording-scheduler'', ''B-mount4cut'', and ''C-cut-postprocessor''  +  mount.cifs -o uid=voc,password= {//$storage.lan.c3voc.de,}/video/intros
  
-After modification, start the workers via the main screenrc on both recording cubes and release encoders:+Finally on all minions, including the one acting as storage, start the following systemd units: 
 + * ''crs-encoding'' 
 + * ''crs-postencoding'' 
 + * ''crs-postprocessing''
