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

[edit] 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
