QuakeTV is a common name for applications with a common purpose - to broadcast Quake matches to big amount of observers.
Bandwidth requirements
- 4on4 match takes around 7kB/s
- 2on2 match takes around 3kB/s
- 1on1 match takes ardoun 1,5kB/s
- QTV to server takes ALWAYS only 7kB/s max (depending on the game mode)
- One QTV connected, 4 ports running 4on4 would be 1*4*7kB/s = 28kB/s between QTV and Servers
- QTV to client takes number of clients * 7kB/s max (depending on game mode)
- One QTV connected, 4 ports running 4on4 each, 10 specs on each = 1*4*10*7kB/s = 280kB/s
Requirements
- ezQuake 1.9 build 2105 or newer, or
- FTE 3343 or newer
Common client commands
/cmd users or /qtvusers to check connected clients
/cmd lastscores similar to KTX lastscores command
/demo_autotrack 1/0 uses KTX autotrack information stored in the stream (so they should be identical in KTX and QTV).
/autotrack with ezQuake 1.9 stable will be the same as above. So you can use your existing 'autotrack' bind for the same function while on QTV
Clientside variables for ezQuake
To connect to a qtv server: Windows: running "/register_qwurl_protocol" in the windows based ezquake client will do the work to register a qw:// URL handler
Linux: launches ezquake with command line arguments to immediately execute a "/qwurl" command. Example: ezquake-linux-x86_64 +qwurl qw://3@qw.foppa.dk:28000/qtvplay
Obsolete:

Clientside variables for FTE
QTVCL_EZTVEXTENSIONS
Enables extensions unique for EZTV such as chat support.
Servers
Differences between QTV observer and Qizmo observer
| Ability/features | Qizmo | QuakeTV | Remarks |
|---|---|---|---|
| Spectalk | yes | yes (delayed 500ms) | QTV chat requires ezQuake 1.9 or FTE 3343 |
| Maxspectators | ~100 | thousands | |
| Bandwidth usage | max server allowed | 7kB/s 4on4 | depends on the number of players |
| Server cpu usage | same as for player | 0% | on 2GHz K8-cpu one player takes 1% cpu |
| Autotrack | yes | yes | |
| Follow commentator | always | switchable | |
| Weapon stats | +wp_stats | +cl_wpstats | +cl_wpstats can be modified! |
| Ability to track anyone | no | yes | |
| Smooth experience | sometimes | the best possible | QTV/MVD data will be interpolated |
| Finetuning | no | yes | check QTV wiki for more info |
| Vulnerable to network lag | yes | not playback | QTV chat could be delayed (finetuning possible) |
| Delayed playback | realtime | delayed | QTV: 1s delay during prewar, 7-10s delay during game |
| Flood protection | no | yes | can be configured in QTV |
| Ignore properties | yes | no | |
| Multiview | no | up to 4 players/screens | requires compatible client |
Troubleshooting
Problem: QTV is not responding to UDP status command
This is most likely due to port 28000 not accepting connections.
sudo ufw allow 28000/udp
